What People Say About Dr. Jun-Ichi Ohara, MD
His office staff speak almost entirely in Japanese. Many of them have limited English proficiency. His colonoscopy instructions are somewhat difficult to understand. He gives them to you on a sloppy piece of paper. I'm sure he knows a lot about gastroenterology. Overall, though, not a very positive experience given the number of other specialists who are available.
