Patient verified via Press Ganey

It was my first time seeing Dr. Oh. I'm incredibly picky regarding my choice of a doctor. I was pleased with Dr. Oh. He was straightforward, yet polite. He listened, yet made recommendations. He accepted my decisions, yet if he thought something was important that I chose not to follow up with (like the pneumonia shot), he suggested that we revisit the topic in another appointment. He went over my health history and lab results thoroughly yet efficiently. I REALLY liked that Dr. Oh sent a message through the portal requesting that I get bloodwork done prior to my appointment. It really bothered me last time I had a physical because the provider had me do my bloodwork after the appointment then I had to go in afterwards for her to tell me my results. None of my results were even an issue, so I viewed it as a waste of my time. Then I got the bill for that follow-up visit which insurance didn't cover. Not good. I am happy to have finally found a doctor I'm comfortable with after my other doctor retired several years ago.
