We’ve been coming here for decades. I had my braces done here. My daughter had her expander and braces done here. We’re thrilled with the work and the office is such a pleasant place to visit. Highly recommend

I was a previous patient of Alpine and Rafetto for braces as a young kid and a current patient of 302 Orthodontics for some preventative work. Dr Fiss was my orthodontic provider for both processes. He has been extemely proficient and I have been very happy with both outcomes. I have dysfunction in my temporal mandibular joint which causes pain and difficulty in opening my mouth. Dr Fiss and his entire team were supportive, empathic, and extremely accommodating to help me in successfully getting the devices/appliances recommended by dentist and oral surgeon. 302 Orthodontics went above and beyond in helping me and keeping me comfortable during the duration of my treatment and answering any questions that came up. I am really appreciative of this practice and would recommended it to anyone!!
