Easy To Converse With
The most important thing about Dr. Karavadia is that he listens to his patients and then gives medical advice that is comprehensive and thorough. He practices under the most modern techniques and does not utilize outdated methods to mitigate your condition, as some other Urologists do. I find him to be easy to converse with and I believe he truly takes his patient’s well being with utmost care.

Consistently Patient and Family Friendly
Well organized and well run offices. Dr. Dersch took/takes the time to talk eye to eye with my husband and I. He makes sure we understand diagnosis and treatment options. I’m a nurse, but I didn’t tell the office/doc that detail. His communications are consistently patient and family friendly.

So Grateful For The Quality Care
Dr. Taub and his staff went above and beyond for my mother when she developed a kidney stone while she was visiting from out of state. I am so grateful for the quality care she received from Dr. Taub, which was made possible by his caring staff.
