Dr. Jeffrey Klingenstein is an amazing and professional gastroenterologist. He explains everything in detail, has a nice sense of humor, and makes sure you feel at ease when you are in his office.
His office is clean and neat and his team is amazing. Cinthya, Mark, and Dr. Wang (anesthesiologist) made my experience of endoscopy a dream. Their performance is outstanding. I would definitely recommend this doctor and this office to my friends.
