He always makes me feel very comfortable when discussing my medical situation. I’ve had bad experiences with other urologists in the past, so it’s great looking forward to seeing a compassionate doctor who is very kind as well!!

25 minutes late, rude and arrogant. If you want someone who is patient focused, acts in a professional manner, and is easy to communicate with, he is not your guy
