“This was my first time being seen at this clinic and I definitely will be back! The staff made me feel comfortable and were very professional. I saw Dr. Weissmann for my appointment and she is amazing. I felt comfortable talking to her and didn't feel judged at all. Dr Weissmann answered all my questions and explained my treatment plan in great detail so that I know what's ahead of me. I walked out of the office feeling comfortable and educated on the different services they have to offer. I definitely will be returning!!”

Im respecting the fact that they set an appointment for a certain time and was here on time. it would of been nice if they would respect mine. I have kids to pick up and a new puppy at home waiting on me and I've been sitting for 40 minutes past my appointment AND I was early 15 min. At this moment I am still waiting.
