“Indivdual Attention and Care”

Visited on April 11, 2024

You are not just a number in the system; you are treated like a natural person with individual attention and care. Your treatment is tailored to you, and not a one size fits all approach.

“Why didn’t I do it sooner?”

Visited on April 11, 2024

Why didn’t I do it sooner? I don’t think I felt this good in my 20s or 30s. My only criticism of Defy is that they don’t do enough outreach to find people who need their help. I wish I wouldn’t have struggled for long on my own. Traditional doctors don’t have the patient care time to take a deep dive into lab results. Defy breaks it all down, checks and rechecks your labs to customize a plan unique to each patient.

“She is very knowledgable and professional”

Visited on April 13, 2024

She is unbelievable, someone who’s very knowledgeable on the subject while also being a true professional. She is the first Doctor I have spoken to who truly knows what she is talking about. I learned a lot from her and for that I’m very grateful. I look forward to continuing to work with her going forward.
