I have been going to Comfort Care Dental for over 20 years and recently moved. I tried another General Dentist for pain in my tooth because they were open on the weekend but was not happy with their high prices and quotes for services that I was told I needed. I was asked to sign a contract for the future services and to start a payment plan but it seemed like too much money. I went back to Dr. Hsu and drove over an hour but it was worth it. Dr. Hsu’s staff is kind and he is very honest. I trust Dr. Hsu and will continue to drive to be his patient. Unfortunately my special needs son has different insurance coverage, so he had to go to another office which is actually another good Dentist office.

Best dentist in z world! Seriously though. I have had a lot of experiences since I was little that were not so pleasant. Dr. Hsu is the most knowledgeable and kindest dentist I have ever been to. All of my family goes to him now and he actually cares if you’re experiencing discomfort during any exam. Try out Dr. Hsu, you won’t regret it! His staff are really awesome as well.

I have been a patient of Dr. Brien Hsn’s for over 14 years. He is very honest and very gentle. I have had a lot of dental work done by Dr. Hsu and every time, he is very thorough and the work is always painless. I have seen many different dentists in my life time – Dr. Brien Hsu is by far the best!

Cynthia G. from Ontario, CA (Source: Yelp)


PAINLESS!!! Backstory: I had recently had a ton of dental work done in Mexico due to lack of dental insurance, it was extremely painful and I was left traumatized.  Less than one year later my new crown broke and shattered into pieces.  Needless to say I refused to return to the dentist in Mexico and suffer through all that pain. I began my research and found Dr. Hsu.  He had raving reviews most of which highlighted their painless experiences.  I made the decision and I went in.  It turned out he had to drill down the tooth and make the new crown.  I was terrified the day of my appointment.  I was nervous the whole time waiting for the pain, but to my surprise there was NO PAIN!  He gave me the Novocain shot and I didn’t feel it.  It was painless.  He checked me several times to make sure I was very numb.  He assured me that he would not let me feel any pain and it was true.  I am so happy I decided to pay out of pocket (I have no dental insurance)  to see Dr. Hsu, the best and most painless experience I have had at a dentist. For those of you who have no insurance like me please don’t consider going to Mexico, it is very painful and they use cheap outdated materials and tools.  Dr. Brien Hsu’s office will set you up with a reasonable price and a payment plan

They really chose a fitting name for their office because I think for the first time in my life I walked out of a dental office feeling great! Really Dr. Hsu and his staff are as good as it gets! It’s nice to go in somewhere and actually feel like the doctor knows what he’s doing. He is VERY thorough and an expert at what he does. For once I felt like my dentist cares. His staff are as nice as they come I would recommend this office to anyone who needs a new dentist. Best of all the work was painless!

Lisa D. from Fontana, CA (Source: Yelp)


Dr. Hsu has been our family dentist for over 8 years now and we are extremely happy with the service and care we have received. He has done general dentistry for my wife and I plus our two boys ages 7 and 3 now. The whole staff listens to the questions we may have and explains all the procedures very well. The staff even let the boys sit on my lap when I got my teeth cleaned so that way they wouldn’t be afraid when it was their turn. We are also very pleased every time we go we don’t have to wait very long to get seen. This helps a lot when you have 2 crazy boys. We highly recommend Dr. Hsu and his staff for whatever your Dentistry needs may be

Baby M. from Los Angeles, CA (Source: Yelp)


Dr. Hsu has been my family’s dentist for many years now.   His staff are always friendly and easy to work with. I have had painful experiences with other dentists, but ever since Dr. Hsu has been my dentist, he helped ease my phobias of dentistry and made all my visits very comfortable. He’s always been very honest with us, being very patient about explaining all the minor details about our porceedures. I remember a time when I was looking to do veneers for my front teeth after watching how they were done on Extreme Make-Over.   Dr. Hsu had done some veneers for one of my friends and they looked amazing. I decided to ask him about doing the samething for me. He was very nice and thorough in explaining the process with both the benefits and the consequences. He convinced me NOT to do the veneers because he didn’t feel comfortable shaving down any of my healthy teeth in order to make them look good. Instead he offered me an alternative – deep bleaching. He was able to make my teeth beautifully white, without having to cut my teeth down! Best of all, he saved me thousands of dollars by not doing the veneers. If there was a way to rate this dentist above 5 starts, I would definitely do so!

Chippy S. from Rochester, MN (Source: Yelp)


Quick, but thorough, and painless. He does the cleaning himself, which I much appreciate!  My teeth feel squeaky clean and smooth.  I already set my husband up for his appointment.  I’m so excited that I finally found a dentist here in CA that I can trust.  Plus I was cavity-free!  BONUS!!

Minnie P. from Rancho Cucamonga, CA (Source: Yelp)


Dr. Hsu is the best dentist I ever had. He is very professional,  caring to patients and did my dental treatment without pain. The staff are very  friendly and nice. I highly recommend Dr. Hsu and you will never regret.  Thank you so much doctor especially to my daughter who referred me to come here. I will surely come back. Dr. Hsu  can be awarded as The Best Dentist In The Universe. 🙂 🙂

Qiana D. from Fontana, CA (Source: Yelp)


Dr. Hsu is so patient and empathetic.  I was terrified of going to the dentist before  I started coming to this office.  He takes his time to make you feel comfortable.  The newly upgraded office is an added perk but I’d still go if the location was less sophisticated because he is so skilled and uses techniques that make dental visits as pain free as possible

Salina L. from Rancho Cucamonga, CA (Source: Yelp)


It’s HARD to find a good dentist, as you know. I decided to try Dr. Hsu for a cleaning since I had received his advertisement in the mail (stating that he studied dentistry at USC) and passed by his location many times. He did the cleaning himself and as most of the reviews here say, it WAS quick and PAINLESS. He was very gentle – a definitely plus! I had no cavities. I floss every night. 🙂 He was very nice as well. I would definitely go back

Mary S. from Upland, CA (Source: Yelp)


All I can say is wow what a find in Rancho Cucamonga. I’ve had my share of dentists in my lifetime from the East Coast all the way to California. This office is great! Staff are polite and friendly. The secret gem is the dentist. Dr. Hsu is such a nice guy and seems to understands all my dental concerns. I didn’t believe it was possible but it’s true – I felt no pain when he did my filling – I mean nothing! From the shot to the finish..

Steve C. from Upland, CA (Source: Yelp)


It is really hard to find a dentist you can trust. It is even harder to find a dentist that you like. I have found both and could not be happier! I read the previous reviews and saw all the 5 stars and wondered what the catch might be, there isn’t one. I have finally found a dentist that will 1)not make me wait forever in the waiting room 2) will actually check my insurance and let me know if a problem is covered and 3)make sure I am completely comfortable during my dental work. It is so refreshing. I have never written a review before but had to for I finally found people truly deserving of it!

Sarah R. from Montrose, CA (Source: Yelp)


I live in Montrose, CA, which is about 45 minutes away from Dr. Hsu’s office. A couple of my friends from Glendale told me that they drive all the way to Rancho Cucamonga to see this dentist because he’s very thorough AND gentle. Well, my previous dentist said I had to do a ROOT CANAL, which is one of the most painful procedures out there. Unfortunately, that dentist (I won’t say his name, but he’s in Glendale) has the hands and manual dexterity of a T-Rex so I decided to put Dr. Hsu to the test. Boy am I glad I did!!!! The entire procedure was painless and I was able to chew normally the very next day. Seriously. I don’t care if you live as far as San Diego (over 2 hours away). He’s TOTALLY worth the trip and if you already live closer to his office then you are a lucky SOB. His staff was very professional and friendly and even the nice calming decor of the office contributed to at least 10% of my relaxation. I highly recommend Dr. Brien Hsu to anyone and ESPECIALLY those that are afraid of the typical dentist

Sam D. from San Diego, CA (Source: Yelp)


Just moved into the area and was looking for a good dentist. At first my insurance sent me to some guy down on Foothill. Needless to say when I stepped out of that office they gave me a laundry list of dental stuff that I needed. I didn’t trust that other guy, so I talked to my neighbor. She recommended that I go to Dr. Hsu. The office looks like a five star hotel – plus the girl’s here at this office were nice and helpful. Dr. Hsu, the main dentist here is amazing. Very thorough in his explainations and he seemed to genuinely care more about my teeth than killing my checkbook. I ended up just needing a few fillings – quite the contrast from the list of dental crap from the other office. On the day of the filling, Dr. Hsu and staff got me a flick to watch and made sure I was comfortable – the whole procedure was completely painless – and this is coming from a guy who’s a total wimp!

Juice M. from Fontana, CA (Source: Yelp)


Great office, probably one of the best doctors I seen. And this is coming from a guy who’s a big wus when it comes to going to the dentist. My gf found this place for me… I didn’t believe I could get my teeth worked on without having pain. Dr. Hsu has like really gentle hands and cared about making sure I was comfortable. I guess it also helps that a lot of the girls there are pretty cute too – gotto make sure they don’t think that I’m truely a big wus when it comes to dentistry lol

Nancy V. from Chino Hills, CA (Source: Yelp)


Dr. Brien Hsu and most of his employees are AWESOME!  The receptionist/secretary can be pretty rude in person.  Other than her, everyone is great!  Dr. Hsu does have the magic touch.  My husband was always in pain after regular cleanings and was pleasantly surprised after his first cleaning.  We’ve been going to Dr. Hsu for two years now and we have had great experiences with this dental office!  We’ve never had to wait long, which is an added bonus.  Don’t hesitate!  This doctor is for you!

G. C. from Rancho Cucamonga, CA (Source: Yelp)


Okay so I finally grew some balls and decided to get my dental work done! I know I’m a grown man and all, but I just never really liked going to the dentist. Never really found that didn’t want to hurt me … So after a great first visit at this place, I came do get my filling done. And the verdict is …. This place rocks! Not only do nurses there baby me, but Dr. Hsu really cared about making me feel comfortable. I have to say this was the most painless dental experience I have ever had… Maybe this will help me grow some bigger juevos and I’ll go see the dentist more often!

When I first started coming here many years ago, this dental office was one of Inland Empire’s best kept secret. Staff is professional and Dr. Hsu is the best dentist I have ever had. I guess it was just a matter of time before everyone else I knew in Rancho Cucamonga, found out about MY dentist. It always seems so busy here, yet Dr. Hsu always takes his time to take care of my dental needs. Rooms are really close together in this office, so I always smile when I hear all the patients next door praising about this dentist and his staff.

Rebecca M. from Victorville, CA (Source: Yelp)


Went in today to get 2 of my wisdom teeth pulled. I was nervous going in but the oral surgeon Dr. Tabibzadeh (an associate and specialist who works with Dr. Hsu) was fantastic. Very thorough, went over everything with me again an took the time to get medical clearance from my cardiologist who I had just seen the day before. Did a pre-op and post-op x-ray to make sure everything went well. I was given the option of medication before the procedure to help me relax, then “laughing gas”. Shots went well. Pinched but I was in the zone so I didn’t mind. While he was working I didn’t have any pain and he updated me on how everything was going and what to expect next. Great bedside manner and all the assistants were nice and professional. Dr. Hsu even came in at the end to see how I was doing and speak with the oral surgeon. They really work as a team and I’m so impressed with all the post-op care instructions to ensure a quick and smooth recovery. I won’t go anywhere else now. I will take a day off of work and drive from Victorville if needed. If you are looking for the perfect caring, professional, dentist office with a team approach and the patient comes first philosophy…look no further than Comfort Care Dental

Rachelle E. from Rancho Cucamonga, CA (Source: Yelp)


Dr. Hsu at Comfort Care Dental has been my dentist for at least 10 years. Very professional and friendly office (and the new office is beautiful!) When I go in for my cleanings every 3-6 months the visit is quick yet thorough. Dr. Hsu keeps track of my teeth and makes sure to fill any cavaties before they develop into a deep cavity. Most of all I know that Dr. Hsu takes pride in his work and it very detail oriented. I always leave the office with a confident smile

Excellent service, a very helpful staff and a dentist who really knows his stuff. I’ve been a patient of Dr. Hsu’s for years and I’ve always gotten great service. His work has always been Flawless and still blends in perfectly with the other teeth after years. Highly recommended

Cat H. from Burbank, CA (Source: Yelp)


I travel to this dentist for one reason. I believe Dr. Hsu is the best dentist period. He has very gentle hands and pays a lot of attention to making sure we’re always comfortable. I don’t know how he does it, but his shots never hurt! He doesn’t even use that numbing cream before giving me an injection – and I still never feel it. I’ve even seen him do work on my children – they think he’s some kind of magician; their mouth goes numb without them even knowing, his work is fast and painless and then they’re out of there- teeth fixed without having any discomfort. When we visit Dr. Hsu and his staff, we always feel warm and welcome. His bedside manners are just so friendly and open, makes me feel like he’s family. People may think I’m nuts but my family and I actually looks forward to seeing our dentist! It’s makes really sad to hear about all the medical problems with his baby. I’ve been reading it on his blog on his website. My prayers go out to his family

Jessie S. from Glendale, CA (Source: Yelp)


Dr. Brien Hsu is by far the best dentist that I have ever been to. He helped me understand the step by step of what was going on and even took the time to give me more reality in what he was saying with pictures off the internet and comparing them to the x-rays that he had just taken. I felt like I could be a dentist after leaving there that day. He has a very light touch and you can tell he really cares about his patients, Even asked if I wanted my water chilled or room temp( Ive never been to a dentist office that offers water like that usually its just in a small display in the waiting room)  Not only will I be coming back here in the future I will be recommending all my friends to him. I live about 35 minutes away from his office but it is worth the ride, I would probably travel two hours to see him

William M. from Rancho Cucamonga, CA (Source: Yelp)


Today was my first time going to Comfort Care Dental.  I have had many bad experiences with dentist but this was not one of them.  I filled out the new patient paper work on line so it made checking in fast and easy.  Everyone was nice, smiled and made me feel very comfortable.  I had a tooth extracted and was nervous about the pain.  But there was none.  They really do take good care of you here.  I will be back

Melissa B. from Arcadia, CA (Source: Yelp)


I came here to get a crown done. I delayed getting my teeth fixed due to fear of pain. To my surprise it was a smooth and comfortable process. I didn’t feel like i was in a dental office. The office was beautiful like a spa. Dr hsu was very communicative for each process he was doing. I didn’t feel a thing! The staff was very accommodating and made me comfortable. I also brought my daughter. She’s a toddler. It was her first experience. I was more nervous for her. But she did great even had a sealant done. She had no fear or discomfort . Dr hsu and his staff are great with kids too!

Abraham M. from Rancho Cucamonga, CA (Source: Yelp)


Dr. Hsu is an OUTSTANDING dentist! I speak about him with the highest regards when ever Dental related things come up. I really got the feeling that he cares about my health which is not something you easily find in a dentist. His back and front office is suuuuuper nice and friendly! Through my visits at this office I also met his oral surgeon. Dr. Tabibzadeh was the man! I had to get my wisdom teeth removed and as far as that goes it was the best experience I could of EVER imagined. The oral surgeon and his staff made sure I was aware of every detail before and after the procedure, I highly recommend! I swear I can’t imagine anyone else doing a better job. I’m writing this review just a few hours after the surgery and my face isn’t swollen, I can talk and I’m even able to eat. In short, I really think that this place has patient care down to the smallest detail. I’d say if your in the area and need some awesome dental care check em out

Sabrina O. from Santa Barbara, CA (Source: Yelp)


My crown cracked and came out! I am new to the area and had no way to know who was good or even GENTLE as I am the biggest baby. I reviewed about 10 other dentists websites in the area, major turn off about it all was that most websites where not informative. I tried Yelp and SO GLAD to read another reviewer say Dr. Hsu was nice and gentle. Another person said, he had the magic touch. Ok that was all I needed to hear. Plus he does work on kids, and look at the name “Comfort Care”. I am here to say if you need to try a dentist or switch, please do yourself a favor and try Dr. Hsu he is a knowledgeable, experienced and a gentle dentist. His staff are organized and kind. His assistants are on top of their game. I was so glad to find him, and will continue to keep going for regular cleanings. Not to mention he is current and on board with all things dental, this made me feel confident he was the right choice

Mike C. from Rancho Cucamonga, CA (Source: Yelp)


More thumbs up for Dr. Hsu. Very good technique when doing cleaning, which he does himself. He uses a waterpik-like device instead of the dreaded scrapers for the most part. Since I hate the scrapers, he makes cleaning a not so unpleasant experience. Would recommend!

K. from Alta Loma, CA (Source: Yelp)


Wow this place is amazing. When I walked in, I felt like I was at the Ritz or at Caesar’s Palace. I never knew a dental office could look so nice and feel so relaxing. I snuck a picture of the dome and chandelier they have in the waiting area – yup they actually have a DOME in their dental waiting area! Ok now everyone knows I’m a scaredy cat when it comes to dentists. And I wanted to find a good dentist – I bookmarked Dr. Hsu’s office for awhile because of all the raving Yelp reviews …. and I finally made my first visit here. All I can say is, Dr. Hsu, his staff and just his office made me feel so relaxed and calm – I almost fell asleep in the dental chair while their computer was doing my x-rays! I was getting ready for the worst when Dr. Hsu came in – I guess it helps that he is actually very pleasant to look at *blush*. Anyhow he just seemed so caring and friendly and was very thorough in explaining to me about my broken filling. When I came back later to get my filling fixed – I felt nothing when he gave me the shot. Before I knew it, I was out of there. I have to admit, I’ve had a lot of dentists work on me – and Dr. Hsu is the most gentle of them all…I think I finally found my perfect dentist!

D. J. from Rancho Cucamonga, CA (Source: Yelp)


Really cool dentist. Been coming here for many years. I think their new office rocks, makes me feel relaxed. Dr. Hsu is always nice and knows when I feel nervous or uncomfortable during dental work – even before I say a word. I had to change dentists because my company changed my insurance. What a big mistake! The other “dentist” told me I had like 10 cavities and did a ridiculous 2 minute cleaning that hurt like heck. He then wanted to drill the heck out of my tooth the same day. I hauled my @$$ out of that place faster than the guy could blink. Ran back to Dr. Hsu and found out I had zero – nada cavities. Cancelled my dental insurance and I’m sticking with Dr. Hsu

Layla R. from Bloomington, CA (Source: Yelp)


My whole family and I have been patients of Dr. Hsu for quite some time now and my neighbor who is new to our neighborhood is looking for a new dentist and asked me what dentist I went to I told her about Dr.Hsu and raved about his gorgeous office and friendly staff and told my neighbor to check out yelp, his reviews are awesome. I was upset to hear after my neighbor viewing Dr. Hsu reviews the recent review that was left. I and my husband actually both have dual insurance and I find it odd that if that was Dr. Hsu case why is it that every time we go in for our check ups Dr. Hsu says everything looks great. I have even mentioned to Dr. Hsu about changing out my old metal fillings and replacing with the white ones and Dr. Hsu didn’t recommend that. Infact his words were if its not broken why fix it? Dr. Hsu has been honest with my family and I would not think about going anywhere else. I hope one miserable persons review doesn’t stop my neighbor from being a potential patient

Staff are very friendly and informative. They make sure about your appointment by reminding you, and no hassles if needing reschedule

Carolyn H. from Adelanto, CA (Source: Yelp)


What a rare find! This dentist really understands people who are very nervous about going to the dentist. His staff and himself are very patient and very nice….. you cannot find another Dentist that will be this supporting of your fear of going to the dentist.I cannot say enough good things about this dentist.  I highly recommend that you make an appointment today.

Renee M. from Rancho Cucamonga, CA (Source: Yelp)


Love this dentist and his staff!  They are very timely, organized and best of all they make the visit as pain-free as possible!  I highly recommend this dentist at Comfort Care. They just recently upgraded their office and its beautiful! State of Art!! Love it!


After graduating top in his High School class as Valedictorian, he was selected as one of the few in the nation to attend the Accelerated Dental Advanced Placement Tract at USC. He then became the youngest doctor in his class to earn the Doctor of Dental Surgery degree – in fact one of the youngest in USC Dental School history. Amongst his many accomplishments, Dr. Hsu has spent a year in 1999 as a volunteer dentist serving families throughout the impoverished areas of California. Since 2000, he has been in private practice, but continues to volunteer his dental services to free dental clinics and charitable organizations throughout each year. In 2002, Dr. Hsu took under his wing a private dental office in Alta Loma that has been serving the Rancho Cucamonga area since 1993. Dr. Hsu has quickly made a name for himself in the neighborhood as “the gentle dentist.” He became well known by many of his patients for providing nearly pain-free family dentistry Immediately, Dr. Hsu’s popularity as “the gentle dentist” grew exponentially and he soon discovered that his small dental office could no longer accommodate the rapid growth of his patient base. In 2012, construction of his new state-of-the-art dental office begun, with a focus on how gentle dentistry could be provided in a comfortable environment. Construction was completed in 2013, enabling Dr. Hsu to move into the most advanced family dental center in the Inland Empire. In his effort to improve care for patients with complex medical problems and sleep disorders, Dr. Hsu continued to expand his knowledge throughout his career, including completing his Master of Science in Orofacial Pain, Oral Medicine and Sleep Disorders at the USC School of Dentistry – allowing him to become a specialist in Orofacial pain in both the medical and dental field. Outside of his compassionate care for his patients, Dr. Brien Hsu enjoys numerous artistic hobbies and was the recipient of many art awards for his portrait and landscape paintings in both water color and acrylics. In addition he has practiced many forms of martial arts and was an instructor for Karate at USC. Many of these skills have influenced his precision and artistic capabilities as a proficient dental surgeon. Dr. Brien Hsu is a member of the CDA, ADA, and is an active alumni for USC.
