The doctor was amazing, truly one of the best I have seen in years. She was kind, in a good mood, never seemed rushed, and was so nice to her nurse. She made me feel comfortable right away and made the whole appointment feel low stress.The only negative was with Providence scheduling, since it took a year to get an appointment with a dermatologist. That is no reflection on the doctor at all. She was wonderful, and I am now on a schedule to have my moles checked yearly, which gives me real peace of mind.Literally one of the nicest and most calming medical appointments I have had in a long time.

Bad - It took a year to be seen as a new patient. As a female, I do feel uncomfortable with male aides/nurses present during my skin check.Good - Dr. Treister is very careful to honor my modesty while checking my skin in front of males. She's very good at that and I really appreciate it. I am also happy that the clinic is close to my home.
