This was a visit to determine appropriate medication and vaccinations for foreign travel. We were taken promptly, treated courteously, given the information that we needed to make reasonable choices, and treated well both by the doctor and particularly, I should say, by the office staff associated with the foreign travel clinic. Thank you.

It was mostly positive. He was behind in his schedule which perhaps caused him to talk speedily which at times was difficult to follow.
