"My first impression of Dr. Posselt was that he is cool, reserved, direct. He is incredibly thorough, and takes his time advising patients of each step. When I was in the hospital, I'd never had better care. He visited me at least once a day; usually more. After the surgery he spent quite a bit of time w/my family, answering all of their questions and keeping them advised of the surgery as it proceeded. I've been so impressed with the follow up and responsiveness he has shown me. I feel quite blessed to have trusted this doctor with my health. I would heartily recommend him to anyone seeking bariatric surgery in the greater California Bay Area."
