Saw the PA and he and the rest were great. Had to wait longer than I wanted and was disappointed that they hadn’t received my test results from my GP. But friendly and professional otherwise.

If I arrive early, he takes me in within a couple of minutes. He takes time to describe the elements of the visit and to explain any details I might require. Very pleasant chair side manner and warm personality.

Efficient with transforming medical needs into immediate follow-up: requested EKG for heart tracking, nurse completed on the spot in less than 5 mins; per responses to initial check in, Dr requested blood draw prior to his check up; draw completed within 5mins; both nurse and phlebotomist were highly competent. Dr had immediate access to my condition, asked revealing questions that got right to medical concern, described what steps to take, walked me up to scheduler and informed what tests to set up, and was fully scheduled and out the door. Excellent experience.
