If you’re tired of traditional health care with incomplete treatment and too little time with providers, Defy Medical is here to help.

“I liked Marissa and thought she was…”
Visited on January 4, 2025
I liked Marissa and thought she was thorough. I particularly liked that she looked at some of my blood work that was out of balance and said, let’s do another blood test to see if we can get to the bottom of why this is always off. That gave me confidence that she was curious and looking under more rocks than other care I have had.,
