The technician was lovely; very patient and kind. She answered all my questions. I did not like the intake process. Felt pressured. You had to pay before getting any treatment. I hoped to switch to an orthodontist right near me. When I asked about that, the answer was, "Well you already paid." So now I drive a distance each month when I could have received treatment in my own backyard. Not happy about that.

OASECT is fantastic. I am currently in the middle of treatment with invisalign and it is going great. I had my wedding a few weeks ago and they were very accommodating with removing my attachments as to not ruin any photos, and then getting them put right back on a week later. Highly recommend going to OASECT vs anyone else. They know what they are doing and are very friendly. Thank you to everyone at OASECT for what you do.
