Happy Patients & Parents

My daughter was having anxiety about visiting the dentist for her first time. Thanks to the super friendly and kind staff she felt comfortable right away. They personalized her experience and we left without a tear. She wants to be a dentist now!

Bringing your two year old little girl to a dentist knowing you're most likely going to hear she needs it pulled due to a bad fall, not something to look forward to. Very emotional time for parents. However, our experience at this practice with the doctor and staff was better than I could have imagined. Everyone was so welcoming, comforting, and all smiles. The doctor herself was kind, very friendly. From the second you walk in it's a very inviting atmosphere for a child. My daughter wasn't in a hurry to leave! Toys and chapstick, what more could a kid ask for
- Katie Bosi
This place was AMAZING! I took my almost 6 year old in for the first time and everyone from the front desk staff, to our hygienist Angela, to Dr. Denise - they were absolutely wonderful! So kind and patient with my very nervous son, they made his (and mine) visit a breeze. I cannot say enough nice things about everyone there. Gavin can't wait to come back in 6 months! Thanks again for a positive experience.
- Emily Loman
My daughter Emma had such a great first dental experience! The staff is very friendly, the office is very clean and decorated extremely well! She loved playing on the iPad while waiting to go back. She also loved watching a movie while they brushed her teeth. The dental hygienist explained everything before she did anything and kept my 3 year old at ease. Dr. Denise is great with kids and so kind. We would recommend this office to anyone looking for a pediatric dentist. I wish I could go here!
