Check out what some of our happy patients are saying about us:

Dana S. from Long Beach, CA (Source: Yelp)


10/10 would recommend Dr. Grella and his amazing staff! An accidental fall caused my upper two front teeth to be badly chipped and even with being a new patient they were able to get me in the day after I called! I went in for my consultation and they ended up fixing my teeth that day and did a fantastic job! They were very professional and aren’t in it for the money, they actually care about you and love what they do. If you’re looking for a dentist I would recommend Dr. Grella any day!!

I had a chipped front tooth “patched” today, easily & painlessly. Trying to preserve my smile for a while longer before I have a caps or veneers put on at much higher cost, possibly later next year. When this is necessary, I will trust Dr.Grella to take care of my teeth.

I would give 10 stars if I could. I had a few fillings done with another dentist, and everything in my bite felt off the second I left. I went in for two adjustments, and still, nothing felt right. Enough was enough with that place, so I decided to call Dr. Grella’s office today in hopes he would be able to help. Kathryn answered the phone and was so pleasant. She told me the following Monday was the earliest available time, but she would call me if something opened up sooner. Two hours later, Kathryn does exactly what she promised. Called me and asked if I could come in today. Just this made me feel so confident that Dr. Grella’s office was the right choice. Thank you so much Kathryn. While filling out the paperwork, Dr. Grella came out to introduce himself, and already knew why I was there before I said anything. You don’t normally think “great customer service” with a dental office, but man….GREAT CUSTOMER SERVICE WITH THIS DENTAL OFFICE. I was brought back almost immediately, and Dr. Grella took his time and was patient in truly dissecting the issue. He looked over x-rays and explained where the problem might be. He then explained what he was going to do before he did it. After a few adjustments, my bite feels so much better now than it did before I went in. To top it all off, he didn’t even charge me for his time today. Just wanted to make sure I didn’t have a miserable weekend. I honestly can’t say enough about what a tremendous office Dr. Grella runs. I booked my next follow up with his office and immediately canceled all future appointments at the other dental office. I wish I would have given this office my business in the first place. Thank you Dr. Grella. Thank you Kathryn. You guys are amazing!

Dr. Grella is the BEST!!! I’m the kind of patient who is terrified of going to the dentist and I start crying even before the Dr. Comes in the room, but I can honestly say that every time I call the office or have an appointment I’m always greeted with a warm atmosphere and a caring welcome. Dr. Grella has amazing chairside manners and he is more than patient with me and makes sure im comfortable when in treatment. If you need a dentist this is the ONE TO CHOOSE, Dr. Grella’s team is just simply amazing.

I found Dr. Grella on Yelp and couldn’t be happier with the service from him and Katheryn. I have been going to the same dentist for about 30 years (most of my life) and changing to a new dentist may seem crazy to some, especially with such tenure like that. He did a procedure on me and took his time to make it look great. I am so pleased! Thank you for the wonderful service!

Joanne M. from Harbor City, CA (Source: Yelp)


My front tooth broke and I was so worried about being toothless over the weekend. I called the office of Dr Will Grella and his front office staff made sure that I get seen immediately the same day. The treatment was painless! It was an awesome feeling to walk out of that office being taken cared of and properly treated. Dr Will Grella is a very conscientious Dentist and will not do any unnecessary treatment that will break your bank.

Tanja K. from Long Beach, CA (Source: Yelp)


My first visit with Dr. Will Grella was simply perfect. He is welcoming, has great attention to details. He is very thorough and has a great understanding for concerns. He is a great listener and he keeps all aspects in mind. He only recommends what needs to be done now. I was very impressed with his approach. He clearly has compassion for what he does. I have known the office staff for many years. They are very accommodating, friendly and extremely helpful and professional. I have already recommend Dr. Will Grella to my family.

Dr grella is great, he communicates with you, easy to talk to, and reassures you, the building has good parking behind it(green brier road going south where it say no parking for 7/11 etc) The lady at the desk is very kind. They also referred to me a pretty decent oral surgeon on katella street when I had some kind of mouth rash (but go to an ENT). Also provides chapstick.

Mike Post (Source: Google)


Dr Will is thorough and thoughtful, and his years of experience in the Navy have made him incredibly efficient. He has a ton of extra knowledge… for example, I’ve had numbing shots in the past, but he is the first to use his “grandfather’s knack” of wiggling the cheek so that I barely noticed the needle! The staff worked with me to get me in ASAP when an old crown fell out last week… I’m very pleased with the entire office.

Jezennia C. from Signal Hill, CA (Source: Yelp)


Dr. Grella and his staff make the BEST out of an experience many do not enjoy. Highly recommend a visit if you’re in the market for a great dentist with very helpful and friendly staff. CLEAN CLEAN CLEAN. Doc doesn’t beat around the bush and takes a good look at what exactly is happening in the mouth. There was absolutely no way I was going to forget my appointment because they are so thorough with reminders via text message, email and courtesy calls!

Sabrina N. from San Marcos, CA (Source: Yelp)


Amazing service and staff! I don’t usually enjoy dentist visits because I have never felt included in the thought process or conversation. This place is different. They told me everything about my treatment and when it came to actually giving me my treatment they seem to be doing the best of the best! Especially the hygienist Michelle. She is so amazing and so thorough. She has a great personality and makes you feel like you’re almost getting a spa treatment while hanging out with a good friend! The whole staff went above and beyond to make me feel welcome! Looking forward to my next appt.

Dr Will Grella is a fantastic dentist. He is personable, exact and clear with answers regarding my dental needs. He is knowledgeable, capable, gentle and thorough. All these years I have been timid toward dental care; now I will continue to obtain my thorough dental care with Dr. Grella. THE BEST DENTIST. Thank you Dr. Grella for your marvelous dental care.

Connor F. from Chino, CA (Source: Yelp)


What an incredibly dental experience. I heard about him through a coworker and he lived up to the hype. The staff at the office was top notch, incredibly professional, and very personable. Dr Grella is great as well. He was thorough, walked me through my Xrays image by image, and answered all the questions I had – he knows his stuff. I’ll definitely be back and happy to have him as my dentist for as long as I’m in the area.

C. A. from Long Beach, CA (Source: Yelp)


Normally I hate going to the dentist but this office is FANTASTIC! first off plenty of parking which is rare in LB,  starting from the reception staff, hygienists, and the Dentist – EVERYONE is friendly, pleasant,  and professional!  The office is clean, well lite, with state of the art equipment. They explain each part of the procedure so you’re well informed.  Can’t recommend enough. 5 stars!

Jennifer Faye (Source: Facebook)


Not being a big fan of the dentist (it has been 10 years) I decided to get a checkup. Dr. Grella is very personable and explains everything to you. He made me laugh and also explained that he prefers to treat issues before resorting to filling/extractions. Very pleased all around.

Janet P. from Signal Hill, CA (Source: Yelp)


Seriously the best dentist & dental team anyone could ask for! (And I don’t say that lightly.) TIME: Just wanted to add that Dr Grella actually offers flexible hours and alternative appointment times, which is a big reason I love this office. (Yelp doesn’t allow him to add this option, for some reason.) If you need an early 7 AM appointment before work, or a Saturday visit, they will accommodate you! You just have to call and schedule it. How amazing is that? I don’t think any other office I know of is so understanding of everyone’s various schedules. PATIENT COMES FIRST: Doctors say this but so few truly practice it, in my experience. Before seeing Dr Grella, two other dentists told me I would need a crown due to a crack in an old back molar filling. I got crown quotes from both of them and was feeling pretty miserable about the impending cost. Then a friend recommended seeing Dr Grella for a final opinion and I went. Dr Grella immediately went to work — no nonsense or dawdling, but still explaining his observations and reasoning every step of the way. (I asked *a lot* of questions about various types of crowns, even 3D printed crowns, and he always answered thoughtfully — never seemed bothered or annoyed by it.) While observing the crack in my back molar filling, he noticed that most of the tooth structure seemed to be intact. After drilling and cleaning out the old cracked filling, he verified that he was right about the tooth structure. Turns out I didn’t need a crown at all — just a new filling! He said nothing beats the original tooth; if it can be saved, it should. QUALITY: Michelle is the best hygienist I’ve ever had. She keeps comfort in mind (glasses to block splashes and numbing gel upon request), but doesn’t pull any punches when it comes to deep cleaning. I’m the type who doesn’t want a gentle cleaning, because that means not everything is getting dug up and scraped off. When Michelle is done, I can even feel how clean my gum pockets are. FRONT DESK: Kathy is incredibly nice and clearly makes customer service her priority. My dental appointments here rarely run late, but whenever they do, Kathy is apologetic and tries to get me in as soon as possible. LOCATION & PARKING: Note that Dr Grella’s office is on the second floor (external stairs), first door ahead. Street parking is available.

Old crown came off-Dr. Grella (and staff) to the rescue! Examined tooth base and suspected some decay(!) So had x-Ray taken w/o crown; yep decay! Temporarily cemented old crown on and I came back NEXT DAY to clean and prep for new crown. Now waiting on the lab to make the crown. I like this dental practice for a number of reasons. 1) They have a sense of urgency when urgency is called for. Katherine was persistent in getting me an appointment to have the prep work done. She had already put in an insurance claim to reduce my expense as much as possible. 2) Sophia, Dr.G’s assistant, personable and works to make you comfortable. 3) Dr.G explains what he is doing and WHY. 4) Dr. G is current on dental technology, the research on the newest/latest dental materials and techniques. He takes ongoing professional training. I have had dental issues for more than 60 years with 10 different dentists. Dr. Grella is the best of them.

I am so glad to have found Dr. William Grella and his great staff. I have had multiple cleanings as a patient and Dr Grella introduced me to a mouth guard to assist me with my sleep apnea. Thanks to Dr Grella, my wife doesn’t wake me up for snoring too loud at night and I’m getting more restful sleep. All have been comfortable, painless procedures with the utmost care. Not only is Dr. Grella a pleasant person, he is a great dentist. In addition, the staff at the office are friendly, accommodating and always willing to help with tough billing questions or scheduling. If you like A+ customer service then you will like this staff. If you are considering a new dentist, I would not look anywhere else. I do not really leave reviews, but I have to spread the love for Dr. Grella and his team, so try them – it’s a no brainer

Will Grella is very personable and runs a great office. His dental hygienist Michelle is the best I’ve ever had. She is so good at what she does. Her approach motivates me to do better during the months between visits. Dental hygienists play the most important role when it comes to dentistry and she’s the best! I am new to So Cal so I consider myself very fortunate to have the best dentist!

Anders E. from Belmont Shore, Long Beach, CA (Source: Yelp)


I have been consistently impressed with Dr. Grella since he took over the practice of my former dentist. I have been going to that practice for over 30 years, and initially was somewhat apprehensive about a new dentist taking over. However Dr Grella quickly put my apprehensions to rest… And has consistently impressed me with his knowledge, diligence, enthusiasm, and skill. He carefully explains everything he’s doing, he uses cutting edge techniques and it’s obvious that he truly cares about providing the best possible dental care. I highly recommend him!!

I just saw my dentist, Dr. Will Grella, for a checkup and cleaning. All the staff are super sweet. I like that Dr. Will’s office uses digital X-ray technology, which means no more hard cardboard swatches that hurt when you bite down. Also, the results are ready instantly. It is obvious that Dr. Will loves his work and shares it by educating patients in a caring yet light-hearted manner. After my cleaning and polishing, I was given an extra — a mineral treatment that will help strengthen my enamel to resist cavities. I had a spa-like experience at my dentist’s office. It was wonderful.

Steve K. from Long Beach, CA (Source: Yelp)


I am a new patient in the past 6 months. Was very pleased with ability to be seen as needed based upon type of service ie broken tooth vs routine cleaning. Like the way he describes what he’s doing and why each step of the way through a visit. My wife was particularly impressed when he called about dinner time to make sure I was ok after the first visit to fix a broken tooth with a crown. Of course, I was fine as I was out to an event. The temporary work was terrific and he was able to work around a couple of scheduling issues for the follow up meeting. Having been in the military I’m inclined, when possible, to use someone with that background and training. Will is a Navy trained dentist and does a great job. His office communicated with my previous dentist to get records very well and his charges seem reasonable for the services. Highly recommend him and his staff.

I have worked in the Dental field for 15 years and am now a nurse. I moved to California a while back and was trying to find a great dentist. I went to one, who lied and tried to cheat me. I recently went to Dr Grella and had a wonderful experience!!! He is honest and friendly. He did an amazing job with my young daughter, who was very nervous to go to the dentist. I highly recommend him to anyone who is looking for a great Dentist!!!

Going to a new dentist can be scary.   Recently my dentist has decided to enjoy retirement but his Dentistry was acquired by Dr. Will Grella.   His staff has always been amazing and I did not want to lose them, so I thought I would give him a try.   My first meeting with him could not have gone better.   He took the time to get to know me and have a conversation before going to work 🙂   He and his team are extremely gentle (IMPORTANT), professional, and helpful.  At the end of my exam and cleaning, I mentioned an ongoing issue with pain on the left side of my mouth.   He instantly was able to diagnose the issue by just making a minor adjustment to my bite.   I HIGHLY RECOMMEND HIM AND HIS TEAM!

James B. from North Redondo, Redondo Beach, CA (Source: Yelp)


This is the best dentist, and team I’ve experienced in my 60 years. He found a problem with a crown that a nameless dentist installed, it was so bad that I had to remove the tooth. The new crown is in now, and it’s so comfortable and perfect that I’m not doing the crazy thing when my tongue is constantly exploring a dramatic change in my mouth. He even felt compelled to give me a break for the cost, he was embarrassed for the dentist that caused the problem (believe it or not, he found the other guy used a fiberglass post which eventually broke the tooth). I am so glad to have been referred to him, and I can happily state that you won’t find anyone that comes close as far as skill, training, integrity and even humor. The staff are all long time employees and even though we are in tough times with Covid 19 you can be confident that you are in capable hands. He recently expanded his practice in a time when some are struggling, I am so happy that more people will now be able to get expert care from a conscientious Doctor. Way to go Doc! Also a shout out to los Alamitos oral surgery center that did the extraction and implant to support the new crown. I never felt a thing except relief.

Katie K. from Lake Forest, CA (Source: Yelp)


Just like you all .. I yelped the “Best dentist” in Long Beach and Dr. Grella popped up! He was awesome when I met him, UCLA grad, and actually does yourDental exam unlike most Dentist who just check your teeth for 2 min. He was so sweet and really cared about my Medical history and myself as a first time client! The two Ladies at the front desk were amazing and Kathy helped me set everything up! I had a newer hygentist, Jaqueline, and she made me feel so comfortable, and if I needed to take a break she would do so. BEST PART – FREE- teeth whitening if you check in on fcbk and I’m so excited to use it! Also, I had a filling on a SATURDAY !!!! Dr. G was so sweet and told me to call/text him a few hours later so he knew I was okay from the numbing. Most dentist would never do that on a Saturday!! So excited to call Dr. G my new dentist!!!!

Marco B. from Long Beach, CA (Source: Yelp)


So far, the best decision we made to see Dr. Grella. He is caring, knowledgeable, explains everything, and takes his time to do the right thing and not do procedures that are not needed. The office staff is accommodating, knowledgeable, friendly, and competent. Even though today was my first visit, I am delighted! My previous dentist did not accept Delta Dental Insurance and was always a hassle to get reimbursed from my insurance, not to mention the outrageous prices he is (was) charging. Dr. Grella’s office team is a well-oiled machine and works with you to get the best outcome. I will add more details as time goes on, but for the moment, a well deserved five stars. Given only today, I can 100% recommend this office who is looking for a new dentist in the LGB area. On a side note: Happy Birthday Sofia Castillo today, who also did an excellent job assisting, and so did everyone else.

Usama K. from Long Beach, CA (Source: Yelp)


Literally the best dentist I’ve ever been to. I recently became a patient of Dr. Grella and I joke that the cleaning was so good I haven’t had to brush or floss ever since! But seriously, though it was a regular cleaning, it felt like a deep cleaning because he is so meticulous and thorough, more focused on quality experience than getting you out as fast possible to see the next patient. He is also very friendly and full of stories and interesting conversation. I admire that he was a dentist in the Navy and is in the reserves, taking care of the folks who put their lives on the line for all of us. I recommend Dr. Grella to everyone in Long Beach and the surrounding area who can drive out to his office. I recently moved from Long Beach to Aliso Viejo and still drive out to Dr. Grella because once you found “the dentist”, it’s worth the drive.

My experience with Dr. Grella and his staff was nothing short of fantastic! I have not seen a dentist in some time, so I was terrified when I had a filling come out and I was in severe pain. Sofia took a number of X-rays and Dr. Grella went over my treatment options very thoroughly. I needed a few fillings and a cleaning. They had me in and out of the office in less than 1 hr and it was COMPLETELY PAIN FREE. I highly recommend Dr. Grella and his staff

Nam T. from Long Beach, CA (Source: Yelp)


I was thoroughly impressed and very pleased with my first time here. This is hands down one of the best dental experiences that I’ve had in my life. It was incredibly easy to schedule an appointment for a check up and cleaning. I was unaware that their office would be closed for two weeks due to the holiday seasons. The first day they opened was the only day I was available to come in. I was very happy that they were able to offer me a same day appointment due to some cancellations on the first day they were back in business. I spoke with Kathryn over the phone and she was super kind and welcoming. When I arrived, I was mainly taken care of by dental hygienist Michelle. She was warm, friendly and patient. She did a very thorough and detailed exam and assessment of my teeth and gave me a lot of helpful patient education and teaching on how to keep my teeth clean. She spent a good amount of time doing a cleaning and recommended that I come back for further treatment. I appreciated her attention to detail and willingness to address my questions and concerns. Dr. Grella was also very warm and friendly as well. He was quick and efficient but did not leave room for anything to be missed. Overall, I enjoyed my first visit here and will definitely be coming back! I’m so glad that my friend had recommended me to come here. I have no hesitations in recommending this place for anyone else who is looking for a great dental practice with exceptional service!

Everything was wonderful. Warm welcoming staff. Excellent dentist skillfull, personable and kind. Gentle hand AND gets all the grime off! If your not satisfied with your current dentist you will more than satisfied with Dr Grella and team!

Colleen Q. from Long Beach, CA (Source: Yelp)


Had my first visit today at Dr. Grella’s office for a dental exam, cleaning and xrays.  Kathryn is the first person you see when you walk in and her smile lets you know you found the right dentist office. Sofia called me in right away and took my xrays. She was very kind and professional.  Dr. Grella came in and introduced himself.  Little did I know he would not only give me my dental exam but also he cleaned my teeth! I think when I made my appointment, I may have not mentioned teeth cleaning, just a dental exam and xrays so since the other hygienists were busy I really got the royal treatment!  If you are looking for a new dentist who is in network, please give this office a call.  You will not be disappointed!!!

Tatiana G. from Long Beach, CA (Source: Yelp)


Dr. Grella and his team are AMAZING!!! Based on past experiences with other dental providers, I always dreaded going to the dentist. Since I found Dr. Grella that has quickly changed. Dr. Grella and his team are friendly, professional, and genuinely demonstrate best interest for their clients. Dr. Grella establishes great rapport and strives to provide best dental work possible. I’m thankful for his service and feel at ease knowing if I ever need anything dental related I can trust him. I highly recommend to anyone. Making my dentist appointments are easy and I never have to wait more than 5 mins in the lobby. Thank you Dr. Grella and your fantastic team!!!

Patty T. from Long Beach, CA (Source: Yelp)


Very pleased by my first visit. I was referred by my husband to this dental office and I was not disappointed. Even before the appointment I had received reminders via text and email with all relevant information so I felt prepared and aware that my appointment was confirmed. I was greeted by a friendly receptionist and Dr G came out shortly after to introduce himself. I was pleased with the friendly and professional approach of all staff and I left with useful knowledge regarding my dental status and ways to improve my dental self-care. I didn’t feel rushed and the hygienist was very thorough and gentle with my cleaning. My teeth felt so clean and the gums were happy too. Already booked my 6-month follow-up. 😉


My grandfather practiced general dentistry in a small town for 40 years with one basic philosophy: recommend and treat patients with the same kind of dentistry that he would have in his own mouth. As a former Navy dentist, I strive for the same kind of honesty and excellence in my own practice. We offer Friday and Saturday times by reserved appointment only. After 5 years of service as a general dentist in the U.S. Navy and 3 years practicing in the greater Long Beach area, I started my own practice. Dr. Will Grella is dedicated to providing his patients with high quality dental care in a comfortable and caring environment. His warm sense of humor will keep you smiling. Dr. Will’s wife, Taylor, operates a successful family business based in Long Beach and shares his passion for high quality service.
