What else would you like to say about your experience?
Dr. Markov has always been very approachable. He's very easy to talk to and he never makes me feel like I'm doing things wrong. He makes me feel like I'm absolutely doing my best and that I don't need to be a perfect number, but as long as we're on the good side and we keep improving, that's okay. And I don't have any anxiety when I come to see him or the facility. Everyone at the facility has always been courteous and kind and respectful. And this is one of the first providers I can say that I've met with that I felt completely comfortable with in telling him honestly what's happening in my life without feeling judged at all. And I appreciate that.
