About Cobb Orthodontics
Dr. Tripp Cobb draws a notable share of adult patients, with reviewers describing him fine-tuning Invisalign results until they're satisfied.
Reviews describe Dr. Tripp Cobb as someone who lays out treatment plans and costs before starting and stays patient with both anxious kids and adults working through Invisalign or braces. Scheduling comes up often as a strength, with appointments starting on time and staff working in extra visits around school or work. Several reviewers mention long-term results holding up years later, including cases where the practice corrected earlier mistreatment from another provider.

The only thing I have to complain about is he made my child a little nervous with all the things going on, but otherwise he was on top of his plan. Now we have to get thr plan started!
Dr. Cobb and his staff did a fantastic job on our son and daughter. Very friendly, professional, and determined to make your smile look fabulous.
This practice has made this process with my 2 sons easy and understandable. They are very friendly and helpful! My 2 sons are approaching the end of their journey with Dr. Cobb and staff. What a wonderful experience. We will miss seeing everyone! Thank you for everything!
Everyone is so friendly, professional, prompt and courteous. Dr. Tripp is an expert! He explains everything, builds rapport with patients and is dedicated to customer satisfaction and the perfect smile possible! 10/10 Recommend!!
We had our first complimentary consultation for my son on Tuesday. Everyone was very friendly. Dr. Tripp explained everything to us and we will be going back to him when my son is ready.
