I love this location! I’ve been coming here for years and have always been pleased. I got Invisalign through them and love the outcome. I recently hurt my tooth and they were able to see me immediately the same day. Very helpful and thoughtful staff.

I really love this Dentist office. Everyone is so nice. I’ve been with them for about 2 years now. I switched over when my insurance changed and my other Dentist was suddenly out of network. This Dentist takes a lot of different insurance- all in network. The hygienists are gentle but effective.nHighly recommend. They are in a strip mall so not the prettiest area but once inside the office it’s very nice and welcoming.

They areeeee so nice. I hadn’t gone to the dentist in a really long time, and they made me feel soooo comfortable during my last two visits. I highly recommend this clinic, everyone is so friendly and make you feel so comfortable. As someone who gets really stressed about going to the dentist, going here really has been helping to calm my nerves. ✨

I have a lot of dental anxiety, and I have been passed around from dentist to dentist, and Dr. Carrie took the time to listen to me and make me feel comfortable. We arranged a treatment plan that I was comfortable with, and Everything was explained to me in detail where I could understand in the past, I’ve had a lot of anxiety with dentist to the point where I do not want to go back, and I am looking forward to going to see carrie and starting my treatment. Thank you apple tree and Dr Carrie ! For a welcoming all inclusive experience : )
