My experience at Mountain Shadows Dental was top notch. I'm not a fan of going to the dentist but the entire staff put me at ease and explained what needed to be done in a very friendly and professional manner. I had a tooth that was bothering me and they were able to get me in quickly and through the whole process have been very helpful. This was my first visit, but I think I'll be making many more to this office!

LOVE Dr. Lere! He works hard to make you feel comfortable and makes that his top priority. Even though he’s crazy busy, he always makes me feel like I’m his only concern, and like he has time to help me. Everyone at the practice is crazy friendly, too, though. I’m always happy to walk through the doors. I highly recommend this practice!

Dr Lere and his staff are the best in the Tri Town area. Our family of six has been with Mountain Shadows Dentistry for nearly 20 years. We’ve had about all the emergencies you can think of and Dr Lere has always been there for us. I was just there today for a cleaning and heard a lot of laughter which tells me he has a lot of happy clients.
