“Amazing staff! Dr. Brown is great, makes conversation, and thorough with his exam. Belinda is the best hygienist! Cindy and Vicky are always so helpful and the entire staff will do whatever it takes to please the patient. I tried going to another dentist...mistake. Dr. Brown's staff is just so kind and genuine. I've been there with and without insurance and they always find a way to make it work. Id recommend them to anyone.“

“This is one of the best dental experiences I have ever had. The staff is friendly, very professional and always willing to help in whatever way they can. I switched from another dentist and wouldn't go back. I feel so strongly about their service, I referred a friend, who is now using their services. Try them, you won't be disappointed.”

“It is rare for me to hear the words, 'I had a nice time at the dentist' but......"I had a nice time at the dentist y'all!" When I say the people here are nice, I am NOT exaggerating! From the moment I stepped in I was welcomed warmly and offered water and coffee. The waiting area is beautifully furnished, cozy and smelled really nice.The Service: The dental hygienist Belinda was awesome! She was so gental while using her instruments, and was in tuned to my comfort level by asking if I was ok. My teeth were cleaned pain free! Dr. Brown seems like a kind and gentle soul, very friendly. He did not have to work on my teeth this visit, but I would trust him to if need be. This office deserves the 5 star rating it has! Vicci was very helpful with insurance matters and information. I'm so glad I came here. I highly recommend! ”

“The office and entire staff is so nice and friendly. Every single person I came in contact with, including the Dr., was professional and attentive. Looking for a new dentist is not always easy.

“Hats off to Dr. Marneni for a job well done for my 3 boys. When Angie at the front desk says she will call you back , she does just that. All of the Staff made us feel So relaxed. My Boys were so comfortable that the oldest ask not to change dentist again. They worked with my schedule which was a WIN WIN for me. I would definitely recommend this office to my friends and family.”
