About 302 Orthodontics
A beach-themed rewards program and technicians who spent nine months easing an autistic patient into treatment show real patience with anxious kids.
302 Orthodontics treats a wide range of ages with braces, clear aligners, and retainers, and reviews highlight how staff work with nervous or special-needs children through pep talks and a Beach Bucks reward system. Many notes mention Dr. Mark Fiss's attention to detail, including coming in on weekends to fix issues, though a smaller number of reviews describe frustration when treatment plans changed or progress stalled. Appointments are generally described as prompt, with minimal wait times and flexible rescheduling around school schedules.

After putting all four of my children in braces with 302 Orthodontics, I finally did it for myself. My treatment is now complete. I'm very happy with my results and highly recommend them for orthodontic treatment. The staff is friendly, and the atmosphere is welcoming and comfortable. You'll also love their rewards program! Dr. Fiss is so very nice and has excellent attention to detail. I was happy to put my trust in him. Stacy assisted on many of my treatment days and is absolutely wonderful. She is very knowledgeable and repeatedly went above and beyond to ensure my orthodontic experience was top notch. Being out of braces now is bittersweet because I will miss you guys! ~xoxo, Josette Maurer (and family)
