What People Say About Dr. Mark Sarnak, MD
Reply
Dr. Mark Sarnak is one terrific Doctor. He has a wonderful bedside manner and and is very interesting and informative about all aspects of kidney disease. I would recommend him to family and friends His staff is very professional And helpful. I think the only negative I can think of is the location of his office. I am challenged when it comes to my walking. I park at valet parking and to walk to 35 Kneeland St. Is very difficult for me.
