    It was mostly ok. But it was my first time with this provider, and it felt rushed. Almost like he was annoyed. Some of the concerns I mentioned to the medical student, the doctor didn't even address. I didn't know if that meant he didn't think it was important or relevant. I wasn't as impressed as I have been with other providers.

    I left the office feeling pretty confident, really extremely confident that the doctor knew what he was talking about and that he understood my concerns. My only caveat is that actually it went by kind of fast and I forgot to ask about another concern I have and I'm going to email the office and ask that question. Okay.

    Dr. Theodosakis is a great doctor. Makes you feel very comfortable. He's always in a good mood. He's always training new doctors. And so there's always someone with them when he examines me. And the new doctors, they're great also. They're a great team. And the office always, always is upbeat. It's a pleasure to be there. It's a pleasure to show up at that office at any time. And I really appreciate them seeing me in the way they treat me.

    Here's a concise comment you could use: "My appointment felt rushed and impersonal. The doctor only asked two quick questions, didn't seem friendly, and left without making the visit feel personalized. It was awkward and didn't meet my expectations for care."
