Yubo Y. from Placentia, CA (Source: Yelp)


Been a while since my last dental checkup and I finally decide to check out Dr Lee. What a smart decision! Diana and Dr Lee are so friendly and professional.Not only Dr lee helped me fixing my teeth, he also explained every step before moving into it like other people said. Very little pain, clear instructions, and very professional explanations. Diana on the other hand helped me a lot by answering all the questions I had. Thank you so much for your patience and time! Now is the second day after the treatment and I felt awesome! Still little sore when I eat but it’s getting much better. I would definitely recommend Dr Lee to all my friends!

Maria J. A. from Ontario, CA (Source: Yelp)


Dr. Lee and his staff are fantastic! Diana and Sandra helped me relax and get over my dental phobia. Dr. Lee is very knowledgeable, patient, kind and gentle! The office is very clean! Not like other dental offices where they recycle gloves! Ewww! I recommend this office to anyone looking for a forever dentist   :   )

I am beyond impressed by Dr. Lee & his staff! I’ve always been so nervous when it comes to any dental visit, but ever since I started going to Dr. Lee I find myself extremely at ease. He’s patient and very informative, and his office manager Sandra, is Amazing! They really do try to make your dental visit as comfortable as they possibly can

Richard P. from Ontario, CA (Source: Yelp)


I went to Dr Lee’s office today for filling work and a really deep cleaning . l really do not like having  deep cleanings done because as much as other dental officers have tried it has been a very uncomfortable experience. This was not the case with Dr. Lee . He put me at ease I could have fallen asleep during the procedure if I didn’t have keep my mouth open. it was the best experience I have ever had Dr. Lee and his staff were very professional I am sold Dr. Lee is my painless dentist !

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


I absolutely love this office. The staff is amazing. Dr. Lee is very caring. He walks you through everything and always asks how you are doing during the procedure. Saturday appointments are wonderful. All 5 of my family member are now going to this office after searching for quite some time for a dentist. I highly recommend Dr. Joseph Lee

Alicia Y. from Hesperia, CA (Source: Yelp)


Dr. Joseph lee is a very honest about how much it cost to get your dental problem done. some other dental office they dont even want to talk about how much it cost or even give you an estemate through the phone.I was escheduled for a dental implant here in high desert around Hesperia and I just dont feel uncomfortable with the dental staff and they made me feel nervous so I backed out and cancelled my appointment, few months later I started looking around for another Doctor coz I didnt want to go back where I supposed to get it done. I found Dr. JOSEPH LEE in internet for a $1,000.00 less of what they are going to charge me for dental implant. So i made the appointment to see him and I ended up getting my dental implant for the first time because I feel comfortable, while im getting my dental implant done my husband is on the other side getting his new crown and went back after few days for more dental implants. I got 3 dental implants done altogether with $3,000.00 savings. My husband and I are very happy of his service we brought our three children’s two of my kids got there wisdom tooth removed, I’m taking my youngest kid for his wisdom tooth remove when its time. It’s a family affair for us getting out dental done in one day at Dr.JOSEPH LEE

Bryan D. from Tempe, AZ (Source: Yelp)


This was the first dentist office that I went to since I moved to California and I was highly satisfied with my experience. The receptionist was extremely professional and personable as she helped me check in. Dr. Lee is an awesome dentist. This was probably one of the BEST cleanings I have ever gotten. My teeth looked absolutely amazing. Thank you Dr. Lee!

Andrea E. from Upland, CA (Source: Yelp)


Great staff, very friendly. Dr. Lee was very informative and explained everything in detail; from X-rays to cleaning and regarding other procedures to  be done. I found them through yelp and my 1st visit was a great experience. I even switched my son to this dental office. And they are open on Saturdays!  A bonus for me. I will definitely recommend them. I am thankful that they were in my network for Aetna PPO

Micah R. from Clovis, CA (Source: Yelp)


Dr. Lee and his team are wonderful! I just moved here and am glad this is the dentist I came to. They were very informative and gave me lots of explanation behind what they were doing and why. I will be back

Steve L. from Diamond Bar, CA (Source: Yelp)


Dr. Lee and the staff of Joseph Lee dental group is the best ever!! Dr. Lee is super friendly and he makes sure you’re comfortable while you are getting your teeth examined.  He is the best dentist ever! I wouldn’t go anywhere!

Howard G. from Durham, NC (Source: Yelp)


Finding a good dentist is like finding a good mechanic.  Having been to multiple dental mills in the past, I’ve built up fillings of mistrust against businesses that focus on profits over the well-being of their patients. I’m no longer enameled by fancy marketing promises of same-day 3D-printed crowns or other convenience-over-quality must-haves that have been drilled into us as a society. I’ve been going to Dr. Lee for the last 2 years, and will keep going plaque because of the quality of care he consistently delivers. I’ve always had a good impression since day 1, as he always takes the time to explain what’s happening and what the treatment plan is. The staff are friendly. Pricing and expectations are established up front and never sugar-coated (but always reasonable). I’ve never been pressured into an up-sell here.  None of my concerns have ever been brushed aside. Brace yourself for his uncompromising commitment to doing what’s right, even if it takes more time or requires more materials. In sbite of this, wait times are excellent, but even if it took longer, it would be worth the wait. 5 stars. Would recommend to anybody who needs a tune-up for their teeth

Helen K. from Corona, CA (Source: Yelp)


Very impressive!  The x-rays they took was high-tech I guess… with one time x-ray, the computer made like 20 x-ray images out of it….  My precious dentist had to take over 20 x-rays on me for the exam.  Dr.Lee was very friendly, informative, and honest.  Great staff, and clean office. I have a little anxiety with dental visits, but Dr.Lee felt very comfortable and easy to be seen.  Insurance benefit and costs were explained very clearly.. Sandra and Diana (I think her name was..) were very very helpful.  I’d definitely recommend my friends and family to go here when they need a dentist.  I got an implant surgery done as well..  very good price, almost no pain, and now I’m just waiting for healing to get a crown over it.  Everything was done by Dr.Lee.. and I’m just a happy camper!

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


Dr. Lee is a fantastic dentist and explained everything thoroughly to me before beginning any procedures. He provided great care and recommended against certain procedures my previous dentist had recommended, which shows how honest he is. I definitely recommend him to anyone looking for a professional, honest, and knowledgeable dentist!

Esther L. from Fontana, CA (Source: Yelp)


Dr. Lee was very thorough examining my teeth and answered all my questions kindly. He treated only what was needed unlike the other dentist who treated things that didn’t needed to be treated at a very high price. This place has a reasonable price, the place is clean, and all staffs are friendly and kind. I will definitely recommend this place to all my friends and families. I am really happy to have found this place!

Mayra Aryam (Source: Facebook)


I was hesitant to go to the dentist because of previous experiences. A friend recommended Dr. Lee so I took a chance. I am so glad I did. I went in for the initial consultation and Sandra was so nice and professional. She’s very good at her job and you can tell she enjoys it. I immediately felt welcome. I was anxious to see my X-ray results but was glad when I was told it wasn’t as bad as I expected. I did the deep cleaning the same day and was very happy to make the next appointment since they put my anxieties at ease. I will keep coming here and have recommended this place to everyone I know

Evelin S. from Fontana, CA (Source: Yelp)


I have been coming to Joseph Lee Dental for the past 3 years. I came to Joseph Lee Dental from another dentist I was not satisfied with. All the staff members here are very courteous and professional. The staff remembers me by name! They have always worked around my schedule for scheduling appointments. The facility is always clean. Dr. Lee is very knowledgeable and I trust his opinion and recommendations.

Hannah L. from Orange County, CA (Source: Yelp)


I was very impressed with the staff, doctor, and the environment itself. The office staff were very generous and although I asked several questions, they never failed to answer with a smile on their faces. Dr. Lee made me feel very comfortable during the whole procedure and barely any pain was felt. He always had an answer with the best possibility for me. I would definitely recommend Joseph Lee Dental.

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


Dr. Lee and his wonderful staff are amazing. I was so nervous to have an extraction done, but they were reassuring and patient with me. Dr. Lee is very informative and his staff was helpful in prioritizing goals to a healthier smile!

Great dentist and very helpful staffs!! I’ve been coming here for 4 years and I should’ve done this review already. Some patients I talked to… they were Dr.Lee’s patients for like 10 years. No doubt about it. There’s no drama here, no long waits, no lies or jokes. Dr.Lee explains everything so well and does the right work.I have had many other dentists work on my teeth but did not last over a year. I also see so many great reviews on Fcebook and Yepl, I’m afraid Dr.Lee might be too busy… I don’t want him to be too popular. lol

Delmis A. from Rialto, CA (Source: Yelp)


I just love my dentist visit. It’s so hard to find a professional and good dentist and I found him today. Thank you so much DR. JOSEPH LEE, I’m very satisfied specially with your services, your attention and with your nice and friendly team, Mrs. Sandra made me feel welcome at your office. Generally the dentists have people that make the cleanliness and other kinds of services to the patients, but in this dentist place the Doctor Lee is the one who personally take care of you. Great, nice, clean and innovative place to get good services

Kim R. from Rancho Cucamonga, CA (Source: Yelp)


Clean, professional, attentive! He fixed an ugly tooth that another dentist did years ago, and took the time and care to be sure it was done right! He does the cleanings himself, with staff helping with suction, etc. Prices are reasonable and I never dread coming here

Barbara Alejandre-Correa (Source: Facebook)


I’ve been coming to Dr Lee for a few years now. He’s very honest and thorough. He offers competitive pricing on all his work. He performs extractions himself and is amazingly gentle. I went to see an Endodontist for a root canal once and he bruised me so bad I looked like I got sucker punched. Dr. Lee has performed 2 extractions for me and never bruised me, stubborn tooth and all. He does everything possible to make his patients feel comfortable and at ease. He doesn’t do it all alone though. Sandra and Diana are extremely professional, nice and caring. They make a great team and share the common goal of making patients comfortable and relaxed throughout any procedure. Dr Lee and his team genuinely care about their patients and our wellbeing. Dr. Lee respects a patient’s decision to decline a procedure if not ready and gives you time to prepare until you’re ready. Granted because he and his team care, they do remind you here and there that a certain issue is till pending your attention, which I have greatly appreciated. Oh, his office makes reminder phone calls to remind you of your upcoming appointment, which to me, is extremely important given my busy schedule. I don’t love going to the dentist, but I enjoy going to Dr. Lee’s office and always leave a happy patient.

Cela C. from Rialto, CA (Source: Yelp)


I recommend Joseph Lee Dental to my friends and family. Very honest dentist and does quality work. The staff is has great customer service. The pricing is competitive with other dentist and I think even better then most. They have worked with me for any payments and have never had any problems with billing my insurance. Initially I was recommended there after a second root canal and I needed the crown done, since then dr lee has been my dentist and recently I took my daughter for check up and cleaning as well and Dr lee has patients to work with children. There location is always clean and wait time is minimal, they have the most current technology with a wide screen to show your X-rays. I’m really happy I found this dentist office! Ps they are open on Saturday

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


I am so happy that we found Dr. Lee Dental.  It was our daughter’s first time at the dentist (she is 3) and he was so patient with her and made her feel so comfortable in the dentist chair for the first time. I also have a major fear of the dentist from past experiences. He was just as gentle and patient with me as he was with my daughter.  He went over all the dental work that needed to be done and explained why and what I can do at home to help, as well. His staff is just as patient and kind as he is.  Even on a Saturday morning, they had a smile on their face.  They had all our paperwork in order and in a timely manner.  They explained our benefits and knew all the answers to our questions without having to say “we have to ask the insurance about that.”I am very excited to go back to start getting my teeth fixed. 🙂

Steve F. from Rancho Cucamonga, CA (Source: Yelp)


It’s a big decision to seek out and find a new dentist who you can trust and develop a good relationship with.  Most of us would rather do anything other than visit the dentist no matter how nice the office is or how friendly the staff are.  You can check out this office without any drama and make a decision if you like what they have to offer.  Dr. Lee and his small staff are highly efficient and will get you in and out with the least amount of inconvenience. This is a small personal and intimate office.  There is one dentist and two staff so you know you will be receiving consistent and personal service.  If this is the type of atmosphere you are looking for…call them you won’t regret it!

Andrea C. from Rialto, CA (Source: Yelp)


Dr. Joseph Lee is one of the most amazing dentist I have ever been in. The staff members are super FRIENDLY and AMAZING! I got an extraction Tuesday Jan. 2, for my right 2 wisdom teeth. I never got an extraction before, but I wasn’t worry because I knew everything was going to be fine and that I was in good hands. Then, today I went to go get my other other 2 wisdom teeth out(left side). It was the quickest extraction ever. I never felt pain and the healing of my right side was fast. Now I’m just going to rest and let my left side heal. Thank you Dr. Lee for an amazing job and for the staff members for being nice and helpful. I would totally recommend this place to everyone who is looking for a good dentist

Mike K. from Corona, CA (Source: Yelp)


I normally yelp for input on deciding where to go. But, I decided to post a review for Lee Dental. I recently had complications with my implant that no other doctor could give me a definite answer for. Dr. Lee knew what had to be done right away. After 3 weeks with 4 visits, my dying implant is as good as new. Cost wise, I was only charged a quarter of what other dentists in the neighborhood were asking. Thanks, Dr. Lee

Mary G. from Los Angeles, CA (Source: Yelp)


We just moved to Rancho Cucamonga & our daughter highly recommended Dr. Joseph Lee to us & we now know why. He is very gentle, kind & informative as a dentist. And his assistants, Sandra and Diana, are so very nice, polite and professional. The office is so clean and very pleasant to come to

Rosel Z. from Rialto, CA (Source: Yelp)


Dr. Lee has an Excellent treatment plan, excellent staff, very professional, clean environment, very courteous and the best thing about it was the final bill., I will recommend this dentist to all my friends and family, it deserves 5 stars rating.

Miae L. from Orange, CA (Source: Yelp)


I recently visited this place through a recommendation I received from one of my acquaintances. At first, I was extremely nervous because I needed a lot of work done to my teeth; however, I was put to ease by the staffs who made me feel comfortable. I was able to receive great oral care from Dr. Lee and I honestly think that he is the best dentist out there. He was extremely meticulous when he was dealing with my teeth and I will definitely be coming back here without a doubt. BTW if there were 10 stars, I would want to give this place ALL 10 stars

Gonzalo C. from Riverside, CA (Source: Yelp)


Dr. Lee is a great dentist! He takes his time and explains all his recommendations and shows the evidence of what is needed. His staff is also great they explain your insurance benefits and let you know your up front cost, no surprises with expensive bills. Office is clean and has high tech equipment, the x-ray machine is great! Would highly recommend this office

Dr. Lee and his wonderful staff are amazing. I was so nervous to have an extraction done, but they were reassuring and patient with me. Dr. Lee is very informative and his staff was helpful in prioritizing goals to a healthier smile!

Jong-Wha B. from Riverside, CA (Source: Yelp)


Dr. Lee comes highly recommended. Very professional and caring.. I’ve known Dr. Lee for about 5 years before he opened his own office last year. All of my family goes to see him for all the dental problems. My two boys (7 and 5 years old) always enjoy visiting him and never say no for their regular checkups. The facilities are upgraded and comfortable environment. Staff members are nice but professional. So I strongly recommend him to all

Kelly R. from Rancho Cucamonga, CA (Source: Yelp)


Today was my first visit. Dr. Lee was very professional, efficient and friendly, as was Sandra! He did find I had a couple small cavities and he made time to fill them so I didn’t have to come back another day, which I appreciated. I feel like I made a good choice choosing Dr. Lee as my dentist!
