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

I have been going to Dr. Anderson for 12 years and had the best experience there! The staff at Dr. Anderson’s office are so kind and knowledgable, and I am always able to get an appointment that fits my schedule. An out of town classmate of mine at St. Louis University had a dental emergency (chipped a tooth), and Dr. Anderson restored her tooth the same day she called. She was so excited with the quick restoration that Dr. Anderson is now her permanent dentist also.

Update: Would give 6 stars if possible. Utmost care and attention. Can’t say enough good things about this practice. Firstly the precautions they’ve taken to protect the patients and staff are second to none. They admins seem caring and professional. The equipment and procedures are head and shoulders above that of my previous dental provider. Dr Anderson and his assistant work as a team and seem really in tune to each other, almost like they can read each other’s minds. Whether this is from years of working together or clairvoyance, I don’t know but it’s very reassuring. Finally the technology they use for scheduling and reminders helps those of us who tend to be slightly forgetful.

Dr. Anderson and his staff are the best dental professionals I have ever used.  Dr. Anderson is knowledgeable, patient, and very good at his job.  His staff has extremely low turnover and has consistently provided excellent service and care to myself and my family over the past several years.  When I moved to this area, I had a difficult time finding a dentist that was knowledgeable, caring, and had a well-run office.  I have found all of that with Dr. Anderson and his staff.  I would (and have) highly recommend them.

My fear of the dentist was completely dissolved after my first visit to Dr. Anderson’s office. He made me feel so comfortable the whole time I was in his chair. Dr. Anderson has not only changed my smile, but he has also changed my opinion of dentistry. Regarding teeth cleaning. My hygienist was extremely friendly! The office is beautiful, and the staff is very professional and welcoming. I highly recommend Dr. Anderson.

First of all, the office personnel are wonderful! They are caring and work hard to take care of any concerns. The hygienists are knowledgeable and very skilled at what the do. They are so nice and thoughtful so you feel spoiled. Dr. Anderson is the best dentist I’ve ever been to in my life. He knows what he is doing, explains everything in a way you understand. He is witty and so down to earth. I fully trust them to take care of my family!

Chris K. from Saint Louis, MO  (Source: Yelp)


Really, I can’t say enough good things about this place. The hygienists are nice and do excellent work. The admins at the front desk are accommodating and easy to work with, they’ll go out of their way to meet your needs and work with your insurance. I’ve had so-so insurance in the past, and they went out of their way to call the insurance company and research what procedures I qualified for. I used to HATE going to the dentist. Now I attend two (insurance covered) cleanings per year. I send my family and closest friends to see Dr. Anderson, because I know they’ll be in good hands.

Mahina N. from Saint Louis, MO (Source: Yelp)


I’ve just had my second visit with Dr. Anderson and I honestly don’t know what the negative reviewers are talking about. I had two substantial sized fillings and Dr. Anderson was emphatic that if I had any pain I could have more anesthetic. He couldn’t have been nicer or more professional. I didn’t have any pain during the fillings and only a moment of discomfort with the shots. I was referred to Dr. Anderson by people at work who have been going to him for years and I now share their enthusiasm. On top of that, both hygienists I’ve seen were excellent and his office manager was very helpful in estimating the costs and directing me to CareCredit to sign up for a payment plan for future work. On top of that, his prices are reasonable for the work. I’ll be going back to him for a crown and subsequent fillings as I am 52 and my childhood/teenage fillings need replacement. I wouldn’t hesitate to refer friends to Dr. Anderson.

I appreciate and highly benefit from the professional, dental care provided by Dr. Keith Anderson and his friendly & highly competent staff. Their healthy practices & attention to my personal dental status is the reason I am commenting here. Also their cautionary steps during the seasons of Covid & the Delta virus has been and remains outstanding. Dr. Keith Anderson is an excellent dentist, I have been his patient for quite awhile, I would know.

Wonderful experience all around! Everyone in the office is so kind, helpful, professional. They are great with communicating and made me feel very comfortable at my visit. Dr. Anderson is highly skilled, and does a great job of keeping you informed on what he is doing while he is working on your mouth. He takes his time and is very detail oriented. Every hygienist that I have had is also very professional and makes you feel at ease during your appointment.

Dr. Anderson and his entire staff are very professional. He and his staff have been providing dental care to me and my family for over 20 years. My twin daughters, who are now 13 years old, took to Dr. Anderson at an early age. All of the dental hygienists, who are moms as well, engage in conversation that kids can relate to. Check ups are easy and educational. Cavities are common with my kids. They have minimal stress because Dr. Anderson and his staff put them and Mom at ease. Thanks for such great dental care and making my family a priority when necessary.

My first time there. I hate the dentist and I regret putting it off so long. But I am glad I found this place. Very nice people which helped put me at ease. What I liked most is I didn’t feel pressure to do a whole bunch of stuff. They shot me straight and gave me options on what needed to be done with great explanations. They didn’t make me feel like I was being upsold on anything. DEFINITELY recommend them and will continue to go there. Also refer anyone looking for a great dentist office.

After years of not being able to see a dentist, I came to came to Dr. Anderson. I had many cavities. For every filling I had with him, he made sure I was comfortable and he took his time with each filling. One time, he even re-did a filling immediately because he just wasn’t happy with it and didn’t want it causing me problems later on. It’s now been several years with those fillings, and I haven’t had any issues with any of them (and seriously, there are way too many of them). The staff and hygienists are all super friendly and nice. We started bringing our oldest son there since he was 3, and they’ve been great with him. Went there during COVID, and felt very safe with all of their hygiene procedures. Overall, I’m more than pleased with this office.

I’ve been going to Dr. Anderson for years — everyone in the office is always warm and welcoming. What’s so impressive right now are the rigorous protocols they are following and their attention to the safety of clients and staff during the pandemic. Dr. Anderson and his team take great care of your teeth, and he takes the time to answer any and all questions you might have.

I enjoy the great care, friendly staff and excellent results from all my experiences with Dr. Anderson’s practice. My whole family are patients with Dr. Anderson and we have confidence in him. I have needed fillings and a crown lately and am pleased to note that the latest technologies are part of the care I have experienced. I highly recommend his practice and love his staff.

Our family has trusted Dr. Anderson and his great team of hygienists for 10+ years! We have referred many friends and family to him as well. From regular cleanings and fillings to more invoked procedures, he has always made us feel comfortable and we’ve always has great results. His office staff is also friendly and efficient and their regular communication and reminders of appointments helps so much with busy people/families. We can’t recommend him highly enough!

Dr. Anderson and his whole staff were were very polite and kind. They were very caring individuals, who asked me very pertinent questions gave me time to ask questions and answered everyone. Very thorough and helpful. Thank you Lynn for being so great with me and made me relaxed. Other appointments, Dr. Anderson and his wonderful team always make me feel welcome. They are all helpful and kind caring individuals. Thank you Dr. Anderson for working so diligently to help create a wonderful smile for me..

Update as of 02-26-21: Dr. Anderson has been my dentist since 4 years and I am very happy with him and all his staffs. Dr. Anderson, knows how to patiently answer questions and concerns in an understandable way. As a scientist, I would say that they have set up a nice infrastructure that would protect both their staffs and clients from the COVID contact. I think they are putting more hardships on themselves for the benefits (health and convenience) of their clients. I believe that they care about their clients health and that is why they are clear, honest, supportive, and very professional. I would highly recommend everyone in the STL area to choose him as their dentist.

Same professional treatment as always. Even with ALL of the added precautions! That’s why I keep going back year after year! I have my next two appointments already scheduled! Their office added additional safety equipment. I strongly recommend Dr. ANDERSON and his staff! I give Dr. ANDERSON and his staff FIVE STARS every single time I have had dental attention, including cleaning every six months, a few crowns in past years, and one filling today!!!!! Even with masks on I can discern RADIENT SMILES on the entire staff and the happy patients leaving the office!!!!!

I had a very happy experience at Dr. Anderson’s office. I had a chipped tooth which I thought needed a crown. It turned out that the tooth just needed to be filled. Dr. Anderson fixed my tooth and checked another tooth in the time that was available, as the office had fit me into their busy schedule. Dr. Anderson’s staff was friendly and helpful. Cynthia was kind and encouraging. I felt very anxious as this was my first time seeing Dr. Anderson. I highly recommend Dr. Anderson and his staff.

Ed C. from Ballwin, MO (Source: Yelp)


I have been a patient of Dr. Anderson’s for a couple of years now. He has always been efficient, accomodating, and thorough. He is very sensitive to making sure I am comfortable. I have found his staff to be very friendly and professional. He recently moved into a new office in Rock Hill and it is absoultely beautiful. He handled my Invisalign procedure and I am very pleased with the results. I would highly recommend him as your Dentist

Mary H. from St Charles, MO (Source: Yelp)


Dr. Anderson has been our family dentist for more than 25 years. He and his staff have been great to work with, and they are ALWAYS nice and accommodating. A few years ago when I was diagnosed with cancer and had to start chemotherapy right around the Christmas holidays, I called his office on the recommendation of my oncologist to get any dental work completed prior to starting my treatment (due to some of the chemo side effects). The office was closed for the holidays, but Dr. Anderson came into the office from his family vacation, in order to give me a cleaning and check my fillings, etc. before I started chemo on January 2nd. How many other doctors or dentists would do that for the average patient? Not only does Dr. Anderson currently treat me, he also treats my entire family…my husband and child, my sisters and their families, my mom. My dad was also a patient of Dr. Anderson’s before his death. Do I/would I recommend Dr. Anderson…ABSOLUTELY YES!

Melissa K. from Saint Louis, MO (Source: Yelp)


Dr. Keith Anderson and his staff are the most compassionate, caring, knowledgeable, professional and thorough group of people, we have found. From the time you walk In, you are immediately greeted by a warm smile from his front desk ladies! His Hygienists Linn and Karen are both super nice and you always get a hello from them both. The office is almost always filled with laughter and you can tell they all love their jobs. You hardly wait and if you are waiting longer then normal, you know it is a true sincere apology from everyone! If I had an emergency, I would hope The dentist would spend a little extra time with me. Dr Anderson is very particular about his work and refers you to only people he trusts. My family and I go to our regular checkup twice a year and who knew going to see them would be fun. We Highly recommend Dr. Keith Anderson and staff!!

Our entire family loves Dr. Anderson and his staff. They are amazing with my young children and make us all feel welcome every time we come in. Everyone is kind, patient, and understanding. The office never feels rushed and I know I can ask as many questions as I need to. We love this office and could not recommend it more highly.

Dr. Anderson has been my dentist for over 10 years and I couldn’t imagine going anywhere else. The staff is friendly and compassionate, the hygienists are warm and professional, and Dr. Anderson himself has such a caring personality…all combine into the best dental care I’ve ever received. I would, and do, recommend highly!

Ginger A. from St Charles, MO (Source: Yelp)


I have to tell you about this Dentist. Dr. Anderson is the only dentist I will ever let touch my teeth for life. Why? Well I am 57 years old and have been afraid of dentist all of my life. For some people they have a high tolerence or a low tolerence to pain… I have a NO TOLERENCE to pain and am deathly afraid of needles even today! I can say this honestly and mean every word of it. Dr. Anderson has filled three of my teeth with no needles just Nytric (not sure of how to spell it but some call it laughing gas. His techs are top of the line and monitor you closely by asking every few minutes how you are doing. I am very comfortable with his chair side manner and he takes his time to get it right. A wonderful family man and pleasant caring staff behind him I think I will always be his patient. B/T/W the man that had a problem with insurance must have been in the wrong dentist office. I have never had a problem with this office rejection for any reason in fact Dr. Painless (as I call him) set me up with an insurance company to make very reasonable payments on these new invisilines I am wearing. After just 10 months my spaced out teeth are becoming glamour shot beautiful. Thanks Dr. Anderson for all you do to make us feel confident in our smiles again . P.S I chose Dr. Anderson when I lived around the corner. I moved over three years ago cross the river and still travel 30 minutes to Dr. Painless office.. Ginger K Patient for six years

Dr. Anderson and his staff are amazing. My husband had a dental emergency after hours and Dr. Anderson came in to fix him up. This was 9 pm at night. Karen, my dental hygienist is great as well. I feel like she gives a great cleaning without “digging for gold”. I would recommend Dr. Anderson’s office to anyone looking for a dentist.

Christina Zebrowski (Source: Google)


I’ve been a patient of Dr. Anderson since I moved to St. Louis in 2010. The staff are absolutely the most incredible people I’ve ever had treat my dental needs. I’m an anxious and terrified patient (due to trauma from my youth), but Dr. Anderson respectfully and patiently works with me and talks to me about everything he does to help ease my nerves. Going to the dentist was never an enjoyable experience for me growing up. It was so bad, that I mostly avoided going to the dentist throughout my 20s. I can honestly say my experience with Dr. Anderson and his team have renewed my trust with dentists.

Update: I had another appointment the day before Thanksgiving. They are still being very cautious with cleaning and have a good air purification system, but there might be up to 2 people in the waiting room at a time now. I actually enjoyed myself a lot. I rarely get out of the house these days, and I also like hearing that I have no cavities. I visited shortly after the reopening and thought they had a good screening process. They had online forms to fill out in advance, and people called from their cars when they arrived. There were only 2 patients in the office at a time and there was schedule staggering to limit contact. I felt like I got the same quality level of care I had at previous visits. Staff members are friendly and devoted to their jobs.

I have always had wonderful, warm and friendly hygienists. They are experts at what they do and my teeth feel and look really clean. Dr. Anderson has a solid plan for my care and always seeks my input in the planning. Great dental care and customer service at Radiant Smiles and I have always been a very reluctant dental patient.Great place, great people.

Oh my gosh what can I say about Dr. Anderson other than amazing. I have had a fairly extensive dental experience in my lifetime with braces and other things and he is by far my favorite provider. I’ve probably seen 8 or more in my life. Gentle, respectful, talented, and just an overall pleasure to have as my dentist. I’ve had substantial dental work with him and pleased with how gentle and careful he was with needles for anesthetic. Great work, great dentist. Don’t get stuck with a nightmare experience elsewhere just call his office. Just as important to note is that his staff if friendly and helpful as well.

Megan Gillooly (Source: Google)


Dr Anderson has steady hands, a gentle touch and is a skilled professional. He is always willing to give you all the time you need to answer your questions or discuss your concerns. The office is spotless and he and his staff are efficient, friendly and knowledgeable. My experiences have always been very comfortable and positive. If you are looking for a dentist I would highly recommend Keith Anderson.

I met Dr. Anderson and his staff almost 15 years ago when I had an unbearable toothache. They saw me at the end/after their work day and were all so kind and skilled. I’ve been fortunate to be under his care ever since! My dental hygienist, Linn, is excellent. And while the office was always meticulous, the way Dr. Anderson has responded to the pandemic is so impressive. Filtration systems, PPE and thorough pre-screening all in place to protect the health of his staff and patients.

Jennifer Gaines (Source: Google)


There are a lot of dentists to chose from, and I am so pleased with my choice! All the staff is extra friendly and kind. From Melissa at the front desk to Carol to Dr. Anderson himself, they make me feel comfortable. Going to the dentist can be stressful! I’ve never felt like I was pushed to do unnecessary work. Because they are good, getting an appointment may take some time. The wait is worth it.

Chandini Avvaru (Source: Google)


I have lived in 3 states and this is by far the best dental practice I have been to. From the front desk staff, to the dental assistant, to Dr. Anderson, everyone was genuine, kind, and thorough throughout the entire process. I had Linn as my dental assistant, and she was a pure gem. She was kind, explained every procedure, and additionally consistently checked with what my insurance would cover so I wasn’t hit with any unexpected charges. I cannot explain how calm and happy the atmosphere was, even during this pandemic. The screening process was efficient & uncomplicated. I will gladly recommend to anyone looking for their next long term dental provider!

Dr. Anderson has been my dentist for approximately 6 years. I came to his practice after my good, long time dentist retired and a fairly new dentist – just was not the right fit. Dr. Anderson is superior in his people and dental care skills (detection, preventative and existing care.) He and his staff are amazing professionals – Simply the BEST!
