Overall Rating: 2.0 2024-05-21

I waited 30 minutes in the waiting room, plus another 15-20 minutes in the patient office room. Once the doc finally arrived, I was greeted with uncomfortable personal questions, unrelated to the purpose of the visit. I made it clear several times that I was uncomfortable and that the questions were not applicable to my visit. Once finally addressing my reason for visit, the entire experience was uncomfortable. Tight quarters (patient room), the doctor did not have a female nurse present or door open.  I wasn't given any warnings about him touching me or in private areas. He also touched my face and mouth without any kind of warning. Just extremely odd and uncomfortable.  Once the exam was over, he told me to "wait in the room because he doesn't know who would be in the lobby".  After several minutes passed, I just let myself out. No follow up was done after I left by the office, no appointment confirmation prior to. Just incredibly unprofessional.
