Joni M. from Rancho Santa Margarita, CA (Source: Yelp)


It’s been one year since my last review and I wanted to update. I am so impressed with Dr Fonmin and his office staff. The staff is so friendly and welcoming the second you walk in you get that big smile from Erin in the front. Erin is very helpful and knowledgeable with any questions you may have including insurance. Dr Fonmin is an excellent dentist. He is so professional and caring. When you are in his chair for any procedure he will explain what is going on in a very caring manner. He is a USC graduate which is one of the top dental schools in the country. He never pushes things on you unless you absolutely need. I highly recommend Elite Dentistry Dr. Fonmin and his caring staff.

Dr. Fonmin and Erin have become family to me! After moving to Southern California for college and neglecting all my dental work, I was afraid of what was in store for me as I knew I had a lot of work to do. Finding a trustworthy dentist was something I knew would be difficult. This is why I consider myself so lucky to have found Elite Dentistry. I’ve been with them for over 10 years now and my teeth has never looked and felt better. Dr. Fonmin and his wife Erin are extremely caring and consistently go above and beyond to ensure you’re taken care of as a patient of theirs. If Dr. Fonmin finds that a procedure requires a specialist, he will send you to an oral surgeon to ensure you get the best work done. I can’t thank Dr. Fonmin and Erin enough for all the care they’ve provided me over the years. I’m a lifer!

This review is long overdue. My family and I have been coming to Dr. Fonmin’s office for 8+ years, and though we no longer live in the area we drive 1 hour twice a year for cleanings, or in my case, fly one hour. Dr. Fonmin, Erin, and the rest of the team at Elite Dentistry are stellar and extremely personable. He and the rest of the staff make sure that patients are comfortable, understand procedures which will be done and what issues they aim to solve, and detailed explanations of billing when necessary. I highly recommend Dr. Fonmin’s practice, and envision I’ll continue flying down from San Francisco to visit Dr. Fonmin (after family) for my biannual cleanings and other dental needs!

Dr. Fonmin and the Elite Dentistry staff are outstanding!  Our family has been going to Dr. Fonmin for routine and emergency dentistry for over a decade.  The services provided are delivered with gentle care and the utmost professionalism.  It’s really great to have a healthcare provider provide both great education, treatment while being very flexible to our our busy schedules.  I’d HIGHLY recommend Elite Dentistry.

Lisa B. from Trabuco Canyon, CA (Source: Yelp)


Dr Fomin has been our family of five’s dentist since he first opened his practice.  He’s handled the routine  visits and emergencies.  My former dentist said PICK SOMEONE WITH A USC EDUCATION! His wife Erin is so kind – his assistants are wonderful and the place is immaculate. We also had to call him for dental advice regarding wisdom teeth extraction and timing- i had to push him but he said ” If it were my child “.  And he was totally correct. He doesn’t run late , prices are fair, and I love how he truly cares about the long term health of our family and their teeth and gums. We have recommended him to many other families and they all happily continue to trust Dr Fomin with their mouths.

Vincent D. from Laguna Niguel, CA (Source: Yelp)


I’ve been coming to this Dentistry for close to 4 years now and I have never had a bad experience. They never keep me waiting more than 10 minutes and the staff is incredibly friendly and personable. The rooms and waiting rooms are all very clean and kept presentable.

Jessica K. from Trabuco Canyon, CA (Source: Yelp)


This is the first time in my life that I’ve actually enjoyed my trips to the dentist. Dr. Fonmin, Erin, and Fabiola are all super kind and professional people that make the most uncomfortable procedures bearable. When I first visited, they found several cavities (ugh), so it actually took multiple visits to finish filling. They took the time to show me the cavities they found with a little camera (mortifying, but enlightening) – something no other dentist has ever done before. They put little sunglasses on you so that you don’t have to squint up at the light shining down into your eyes. Those lights aren’t even really that bad, but it shows how considerate they are to care about even that part of the experience. Besides all that, they are all just super great people I enjoy chatting with when I don’t have tools in my mouth.

Orlando R. from Rancho Santa Margarita, CA (Source: Yelp)


I’ve been coming here since I moved to Rancho Santa Margarita. I absolutely love it. They always tell me the truth, they NEVER push me and are accommodating with my schedule. Exceptional professionalism and  dedication. I hope they NEVER leave RSM. I come here for everything, cleaning / check ups and any dental work I may need.

Brian T. from Rancho Santa Margarita, CA (Source: Yelp)


Dr. Fonmin is awesome! He’s been my primary dentist for about 5 years. He’s always super nice and professional and his staff is always super friendly. I also love how I never have to wait for long periods of time in the waiting room for my scheduled appointments. They always seem ready for me. Highly recommend!

Joan B. from Rancho Santa Margarita, CA (Source: Yelp)


I moved to RSM in 2009 and found Elite Dentistry and Dr. Fonmin.  He is knowledgeable and very personable.  Erin and his staff are efficient and very nice.  I was very impressed that he graduated from USC Dental School – 1 of the top in the US.  I highly recommend Dr. Fonmin and Elite Dentistry.

Danelle C. from Laguna Niguel, CA (Source: Yelp)


Everyone in all of Orange County should come see Dr. Fonmin, Erin, and Fabiola. They are dependable, trustworthy, and professional. I was recommended through my insurance company as well as researched amazing reviews on Yelp. I havent seen the dentist in over 5 years after a frightening experience elsewhere. I was very wary to see the Dentist but my teeth were hurting and so I had to find a new office and Dentist. I was so happy and they exceeded my expectations after my first visit with Dr. Fonmin, Fabiola, and Erin. Erin was so sweet, friendly, informative, and helpful on the phone when talking through insurance and scheduling an appointment. Even better, was that she was the exact same in person. I came in for my second appointment with my fiance for his teeth cleaning and to fill my cavities and Dr. Fonmin and Fabiola reassured me the whole time and kept checking in on me to ensure I was never in pain and was okay. I was so happy to find my family dentist and team here!

Anonymous from Ladera Ranch, CA (Source: Yelp)


Dr Fonmin and his staff are pleasant and considerate.  I typically hate going to the dentist but this one is painless and very professional.  Having recently moved to RSM, I had some bad experiences in the past with other dentists, but I am happy to say I found my local dentist. 11/13/19. Dr Fonmin is a rarity in that he does not push the painful and expensive options on you but provides the full scope of options. I greatly appreciate it!!!

Tiffany D. from Foothill Ranch, CA (Source: Yelp)


This is the best dentist I have ever been too. Erin is the best! My son doesn’t even mind going to the dentist now. This is a pain free place, I have never felt pain while they work on you. I have never felt like a number here, they treat you like they care. I have always left feeling like I got the best deal ever! I will never go to another dentist.

Alyona K. from Mission Viejo, CA (Source: Yelp)


I have been serviced by Dr. Fonmin’s office for almost 6 years now. I am always pleased with the level of professionalism, knowledge and positive attitude everyone has in that office. His wife Erin is just a sweetheart and she understands how  important it is to keep each customer happy especially in their family business. They cover every dental service from the teeth cleaning, crowns, wisdom teeth. They do it all! I can definitely recommend Elite Dentistry for all your dental needs!

Shelley M. from Rancho Santa Margarita, CA (Source: Yelp)


I had to have a front tooth extracted and needed a bone graph to support a future implant. Currently Dr. Fonmin is out of the office and the procedure was performed my his associate. I was extremely anxious about losing a tooth and apprehensive about the surgery. From the first visit with Dr. Fonmin to the end of the surgery Elite Dentistry has provided me with excellent care and a bedside manner that is incomparable to any other Dentist (or health care office) I have ever utilized . I’m a patient for life. Thanks so much Elite

Kathrine S. from Rancho Santa Margarita, CA (Source: Yelp)


I’ve been with Elite Dentistry – Dr Michael L Fonmin’s group for 5 years now and I’m always impressed with the attention to details.  After months going by they know me on the phone and that’s incredible with all the people they serve.  They are all very friendly and my visit seems to go by very fast.  Thank you so much for you service over the years.  Hats off to you, Erin, for always remembering me and showing a smiling face when I come in and when I leave.  I recommend them highly for making them your family dentist.

Beth K. from Rancho Santa Margarita, CA (Source: Yelp)


I have been taking myself and my 2 kids to Elite Dentisty for about 6 year. I have always had an excellent experience and recommend them to friends and family. Nice, friendly environment and provide fantastic service for adults and kids of any age.

Craig A. from San Clemente, CA (Source: Yelp)


Was referred by a friend to Dr. Fonmin mostly because I am a big baby.  I didn’t even tell Dr. Fonmin that I was nervous… He made sure I was comfortable during the entire process.  The best bedside manner!  Also, presented many options so that I can stay in my budget.  Highly recommend!

Tyson F. from Garden Grove, CA (Source: Yelp)


My husband and I absolutely appreciate doctor Fonmin and his amazing team.  His wife Erin is the business office manager and is always so kind and accommodating.  My husband and I had appointments at the same time and so she held our newborn for us while we were getting our dental work done during the overlap.  They are such friendly people and they are very conservative. I was told by another dentist that I needed to get a filling for a cavity when it was actually not a cavity and not necessary. I appreciate the second opinion and them giving us options and not pushing up sale items – deeper cleanings – cosmetic dentistry etc.  The best is that they use a dental pick that works on sonar and your teeth will feel amazing after having them cleaned. I wish I could go in more often than every six months!  At first I thought elite dentistry was a chain and there would be a different dentist rotating in and out, but that is definitely not the case.  I had what seemed to me to be urgent and they accommodated me that day to fix a chipped tooth.  Dr. Fonmin, his wife Erin, and Fabiola are your go to people for five star dental care.

Lili F. from Rancho Santa Margarita, CA (Source: Yelp)


I highly recommend Dr Fonmin and his team. He is very knowledgeable, trustworthy, compassionate and truly concerned about your overall dental health. He and his team always take the time to ask how are you doing and make you feel like family. They make going to the dentist less stressful. Erin is amazing, professional and caring. She always follows up. The office is clean, well maintained and equipped with the latest technologies. I have been his patient for the last eight years and I could not be more happy and satisfied with his service. Thank you Dr. Fonmin for all that you do.

Yosida P. from Aliso Viejo, CA (Source: Yelp)


Dr. Fonmin has been my family dentist for a long time. Whether it is an emergency or not, he always concerns of his patients need and comfort.  I am very grateful that he had referred me to the best periodontist & endodontist. Erin and Fabiola are sweet ladies in the office. Erin is always helpful when  it comes to the insurance billing. Thank you for being awesome! I highly recommend Elite Dentistry for your family dentist.

Margaret L. from Costa Mesa, CA (Source: Yelp)


Happy to have found a dental office in my area where I felt comfortable on the first visit. Dr. Fonmin and his dental assistant were both professional and informative while taking x-rays, giving a comprehensive thorough exam and teeth cleaning. Erin in reception is extremely pleasant and welcoming. Plus the office is spotless clean so back for a follow up soon!

Gaurav A. from San Diego, CA (Source:Yelp)


I’ve been going here for 8+ years and still drive back to see Dr. Fonmin even though I now live over an hour away. He is a very trustworthy and personable dentist, and Erin is really sweet and welcoming as well. I also had a tooth emergency a few years ago and they were very accommodating and able to schedule me in immediately. Nobody likes going to the dentist but I’ve only had great experiences at this office. Very highly recommended!

Nancy J. from Rancho Santa Margarita, CA (Source: Yelp)


This was my second check up and cleaning at Elite Dentistry and I am very happy.  Erin is the sweetest person on the phone and in person. She was very helpful with insurance questions.  I like that Dr Fonmin did the cleaning and exam and then the assistant polished my teeth. Their cash patient price was very reasonable. Best of all my teeth looked great after!

Aleta N. from Rancho Santa Margarita, CA (Source: Yelp)


I have been going to elite dentistry for almost 10 years of care, compassion and expertise. The professionalism and kindness of Dr. Fonmin, his wife, Erin and the hygienists are unmatched. I never have to wait more than 10 minutes for the doctor, and scheduling is flexible. I walk out smiling brighter and bigger. I definitely recommend!

Ema F. from Mission Viejo, CA (Source: Yelp)


Recommend this office to anyone looking for a wonderful dentist. Everyone here was incredible… absolutely loved our service and will definitely be going back. Erin at the front was the sweetest lady ever!! She made the whole experience so easy and comfortable. She just seems like an amazing soul. They didn’t push extra services on us and gave us tons of information … great experience and great staff
Thank u!

Victoria L. from Rowland Heights, CA (Source: Yelp)


My family and I have been coming to Dr. Fonmin for many years now–since I was a little girl! It’s our go-to for a check up and cleaning. The staff is very friendly and they all have such nice humor as well. It’s a lighthearted place that makes going to the dentist enjoyable. They also give out these cute colorful toothbrushes after every check up. Thanks for the wonderful service Elite Dentistry!

Kevin M. from Rancho Santa Margarita, CA (Source: Yelp)


I have been seeing Dr. Fonmin for years and am extraordinarily pleased with my experience here. Dr. Fonmin always explains what is needed, what my options are and what he is doing, step by step. He is very personable and I have never felt rushed or that I was receiving more treatment than was needed. So I can focus on understanding my treatment and not avoiding a “Sales pitch”. And Erin is wonderful, too. She always has time for my questions regarding insurance and billing and is a pleasure to deal with. Unlike my last dentist where the billing department was a nightmare (not returning calls, over charging). You can’t see a better dentist in RSM!

Janelle G. from San Clemente, CA (Source:Yelp)


Elite dentistry is a great place to go for any dental work. I have been going for years and even though I moved 30 minutes away, I still make the drive. I have always had a pleasant time even when I don’t get the best news about my teeth and tell everyone who asks me that I love this dentistry. Dr. Fonmin and his wife are such kind and overall great people. They always make sure to explain what is going on, make you feel comfortable, and provide great dental work! Even when I haven’t gone in awhile, they remember details about our conversations from the visit before. I highly recommend Elite dentistry!

Chanele C. from Irvine, CA (Source:Yelp)


My family and I have been going to Elite Dentistry for over 14 years now and we will not be going anywhere else. Dr. Fonmin, Erin, and the staff are absolutely incredible – so warm, friendly, and accepting. Dr. Fonmin truly cares about his patients and believes in doing the right thing. Every time we visit, it is such a positive experience – hardly feels like going to the dentist at all! Is it weird to say that I’m excited for my next appointment? 🙂 If you are looking for a new dentist, don’t hesitate to choose Elite Dentistry; you will be in good hands.

Valerie S. from Irvine, CA (Source: Yelp)


Dr. Fonmin has been my one and only dentist the past 10+ years. He is always happy and does great work. I love that he and his wife operate together too. I refer Dr. Fonmin to all. If you’re looking for a good, honest, professional, happy, friendly dental practice, Elite Dentistry is the place!

Kenichi S. from Montebello, CA (Source: Yelp)


I’m a person with quite a bit of teeth problems.  My teeth and gums have always been weak all around.  Not to mention I get cavities very easily.  Due to my situation I had numerous dentist perform different work on me throughout the years.  Another thing I should mention is that my pain tolerance is very Low so quality of work and someone that has patience is very important to me.   If any dentist can work on me then I would say he is the ideal dentist.  I can sincerely say Dr. Fonmin is that rare truly exceptional dentist that I was looking for and I was fortunate to have come across him especially knowing that I have multiple dental issues to deal with.  When I got what are normally more painful procedures such as a deep cleaning, working on my root-canal and removal of my original tooth Dr. Fonmin was very attentively asking me about my comfort level all throughout and his work I was very smooth and gave me very minimal pain.   I have a healthy set of teeth today and that is all Thanks to the worked performed by a highly experienced dentist such Dr. Fonmin.  By the way, the staff there at the Elite Dentistry is very professional, funny and good-heartedly friendly as well.  I really liked this place but most importantly Dr. Fonmin’s work was the best for me by far and I would highly recommend this dentist!

Sherri M. from San Clemente, CA (Source: Yelp)


Dr. Fonmin is amazing.  I usually hate going to the dentist, but he is gentle and quick.  I have been going to him for several years and my teeth have never looked better.  His staff is friendly and work around my schedule to get me in when am available

Bryn A. from Newport Beach, CA (Source: Yelp)


Dr. Fonmin is everything you want in a dentist – thorough, talented, gentle and honest. I saw him a few times some years ago and then came back after I moved away because my other dentist was going to charge me $1,350 for something that Dr Fonmin charged me less than $200 to do. I’ll be making the drive back to him in the future because good work and integrity should be rewarded. Erin at the front desk is fabulous too!

Raq H. from Trabuco Canyon, CA (Source: Yelp)


Super awesome dentistry! The employees here are very professional and polite. I love that they are always willing to start conversations so that you don’t get bored while having your teeth polished and cleaned (it’s a legitimate concern!) Added bonus for the awesome music selection in the background! Love this place and would highly recommend it to everyone!
