DR. SAVANT MEHTA, MD REVIEWS

I saw Dr Mehta for appointments at his office and for procedures at another location, I found him to be caring, knowledgeable and compassionate. The office staff couldn’t have been more helpful. I was being seen for a couple different reasons and required a lot f communication with his office and not once did anything get missed or fall through the cracks. Dr Mehta has a style that can be humorous at times which was great, however when it came to business he tells you like it is with no sugar coating or beating around the bush. I recommend him.

Dr. Mehta is a smart, knowledgeable, and thorough doctor. I went and had labs done and the lab tech said: "don't ever leave this doctor " that's because in the 23 years she has been a lab tech she has never seen an extensive set of tests. I like his straight to the point, no sugar coating technique of communication with me. I would highly recommend him to any and all looking for a great doctor.
