Read What Our Patients Have To Say About Our Dentistry

Customer reviews are highly reliable when you have to make an informed decision about your dentist. Below are some reviews we’ve received by our patients.

“As a dentist myself, there was no one I trusted more to do my dental work and implants when I was in need. A professional job through and through.”

Dr. David Shock - 1 month

“Like a few other reviewers, I had not been to a dentist for 6 years, since I was 18. Dr. Marrs and his staff made me feel extremely comfortable, took the time to explain everything, and were very pleasant. I am no longer afraid of the dentist!”

Rose Tryon - 2 years ago

“I had not been to the dentist in 6 years because of a prior poor experience with another dentist. My wife dragged me in and it was simply an awesome experience with Dr. Marrs and his staff. I had 2 bridges, a root canal, and 2 cavities. I didn’t feel a thing and now plan to go every 6 months….The best dentist ever. I am no longer afraid! What impressed me the most is the convenience! Dr. Marrs even got me in on New Year’s eve at 6:00 AM with just a few days’ notice. He even answers the phone sometimes when his staff is busy doing other things. Finally, Dr. Marrs is brilliant. He was a licensed pharmacist before he became a dentist. Two tough degrees from Butler and Go Bulldogs. Finally, my daughters and wife simply love him. I recommend him to anyone I see.”

Jim Milborn - 2 years ago

“I had only been to the dentist one other time in my life before visiting Dr. Marrs (I’m 25) and was, of course, scared. The staff was extremely pleasant and Dr. Marrs was very thorough and explained everything that he needed to do and was very gentle about it, making sure I understood the procedure and costs associated. The following week, I got all of my work done and experienced no pain at all – he made sure that there was no discomfort and I really felt at ease. I’m no longer afraid of dentist visits and will absolutely stick with this office! They are fantastic!!”

“Fantastic place. They are always upfront about cost of work and time commitment. The staff routinely goes above and beyond to make sure everything works out for you.”

Ingrid - 1 year ago

“I’ve been coming here for about 4 years. My husband and I both love Dr Mars and his staff. They’re always friendly and flexible with our schedules. Dr Mars is the first dentist I’ve had who takes the time to explain what he is doing and why and why he recommends the things he does. I can’t imagine going anywhere else.”
