Each visit I’ve had with Dr Knapp has been a great experience. He takes the time I need to talk with him regarding my current health issues. The last visit I had with him in early April, he asked me if there were any issues I wanted to discuss with him and I did have some things I’ve been dealing with as I’ve gotten into my mid [omitted]. He recommended a medication to me that has made my life much better with my current issues. Thank you Dr Knapp.
