“Consistently good experience over the years”

Visited on November 22, 2025

I’ve been a patient at Defy Medical for almost four years, and Jill has been the person I’ve worked with the entire time. She’s honestly been great.

Talking about personal medical stuff isn’t easy, but Jill makes it comfortable and low-stress. She’s knowledgeable, confident, and very easy to talk to. She has a great personality and never makes you feel rushed or awkward, which really helps when you’re trying to ask the right questions and understand your options.

She’s made every consultation a good experience for me, and I really appreciate the care and consistency she brings to her role.

“Jill has the rare combination of clinical expertise and a great personality”

Visited on January 13, 2026

Jill was the first clinician ever to go over with me, in detail, the results from my CBC, metabolic panel, lipid panel, and testosterone total and free. In addition we had a delightfull conversation about life and on the holistic nature of all the constituent factors influence health. This is my fourth visit with Jill and at 50 I have never been this fit, healthy, or content. She’s also really funny and you can tell she really cares.
