Dr. Kosmorsky's appearance was fleeting. He was direct with his findings, albeit brief in their discussion. He prescribed an over the counter supplement and then proceeded to disparage the vitamin industry. My reason for the visit was to discuss a condition I had had in the past and what I should do if it re-occurred. I was not satisfied with his response to this. He exited, not having asked me if he could help me with anything more.
