About Defy Medical

A male doctor in a lab coat holds a stethoscope and crosses his arms over his chest.

We specialize in Men’s Health, Women’s Health, and integrative therapies via telemedicine.

Defy Medical’s goal is to treat the whole patient, not just one or two symptoms.

We’ve offered telemedicine care for more than a decade and helped thousands of patients achieve better, happier lives. Our providers are experts in the field of integrative medicine and bring their expertise to you with extended consults and customized care plans.

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

“Professional and Refreshing – Great Appt”

Visited on September 1, 2023

I had a lab follow-up and med review with Jill. She was very professional and did a great job reviewing my labs. She spent time explaining certain things and left feeling confident in my treatment plan. Getting someone to take the time and make you feel like you matter as a patient is hard. I highly recommend Defy.

“I really like my provider”

Visited on September 13, 2023

I really like my provider, Michael. My husband and I are both with Michael. We’ve been with him for a few years now. I feel he really listens, which I’ve found is not easy to find in a provider. He’s great at answering questions. I feel he’s knowledgeable. He also understands that his patients know their body and how they’re feeling and he listens to our feedback about what we feel we need. He makes it easy to come up with a treatment plan and make changes when needed. I’ve had a good experience as well with all other staff any time I need to call in.

Well Being
Every time I have a consultation with Dr. Calkins, I feel as he really cares about my well-being . Not only he goes over my blood test results , but also asks about how I’m feeling . Listens to my concerns/ issues and offers his best medical opinion and expertise on how to improve and balance my hormones.

You can then take these recommendations to your local provider for more specialized care.

We cannot prescribe and ship medications overseas.
