First time here and staff were very friendly. Saw Dr. Gonzalez and was very informative and answered all my questions. They also help you with payment plans. (Super helpful) Thank you for a great first experience!

Smile Well team were incredibly helpful. I was feeling anxious, but Ms. Josie helped calm me down and made sure I felt comfortable throughout the process. She treated me with great care. Smile Well is very affordable, and I highly recommend asking for her services—she’s a very kind young lady.

Very pleasant staff, facility was nice and they explained everything well. They answered all my questions and were patient. I made a mistake on my appointment time but they were accomodating and fit me into their busy schedule. With all due respect, it doesn’t hurt that Dr. Gonzales was very easy on the eyes! She also very good at her job. I will be returning for additional oral care.
