Dr. Zlotoff spent a good deal of time with me and gave a thorough explanation of my current health status based on my lab work and other tests. He explained how he saw my treatment and follow up going forward. He listened to my and my husband's questions and concerns and gave answers and reassurance. We were both very satisfied with this experience.

Dr. Zlotoff is amazing! He knows my history extremely well, always begins with a pleasant greeting, followed by my input regarding how I'm feeling (asking specifically about anything I don't mention), discusses any recent lab results (including how they relate to past values), does the physical evaluation, invites me to ask questions (and listens attentively and responds thoroughly), tells me when my next visit will be and makes sure I know where to go in what order when I leave his exam room. (I had another appointment and a blood draw.) He also reminds me to make an appointment on my way out. Messages about test results are timely, usually within 24 hours. Although I'm doing great now, his obvious thoroughness, intelligence and ability to explain even things that could be upsetting inspires confidence in patients and their family. I am eternally grateful!
