Dr. Katzman diagnosed my issue within minutes, prescribed medication which cleared up the issue within a month. I had a follow-up tele-visit with him a month after the first appt. During both visits, Dr. Katzman's attitude, expertise, and communication skills were excellent, maybe the best doctor visit I've had in my life. During the telephone-visit, I asked him several questions, and I felt like I was talking to a good friend, easy, not rushed, kind and compassionate. I would happily recommend Dr.K to anyone.
