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.

Dr. Markov is truly exceptional. I’ve been his patient since 2023 after being referred for thyroid nodules, and he has consistently gone above and beyond for my care. He genuinely listens, cares about his patients’ health, and always makes sure I’m connected with the very best specialists when needed. I’ve always felt supported and in great hands with him. He is truly one of a kind.

I was there right on time or two minutes late due to traffic. I waited five minutes or a little less the doctor came in and seemed rushed. The whole appointment was rushed and I didn’t have energy time to ask any questions. This was totally unlike my other visits with him.

I come to my mother's appts with her she is 82 years old. She stated to me she really likes him. I am hoping here insurance company and bjc reach a agreement so we dont have to go elsewhere for her needs. He is caring and explains everything and answers all of our questions and beyond.
