How does retreat work?

Our philosophy is simple, and our recommended health plans are easy to follow. Visit our How it works page to learn more. 

How is retreat different from a regular primary care doctor?

We took every aspect of a conventional medical visit and turned it on its head. Our booking process is straightforward and fast, as you can easily view upcoming appointments with your provider and schedule a virtual or in-office visit right on our website. If you do choose to visit one of our state-of-the-art offices, you’ll notice it looks nothing like a typical doctor’s waiting room. You can enjoy a healthy juice at our juice bar, Starbucks coffee, and lounge in a comfortable and inviting space. When it comes to a visit with a provider, you’ll notice our approach is to treat the whole YOU and not just the symptoms, which is commonly practiced in medicine today. You’ll build trust with your provider as he or she spends time learning about your health goals, habits, and finding long-term solutions to help you become the best version of yourself.

Do you accept insurance?

At this time, insurance does not cover functional health services. We are working diligently to try and make an impact on this standing.

What are Thrive, Retreat and Retreat+ subscription health plans?

Our providers will work closely with you to create a plan that can help you achieve optimal wellness. That may look like blood panel check-ups, supplements and nutrition, vitamin injections, and regular consultations to assess progress. We offer three levels of subscription plans that can ensure you’re receiving the support you need to keep feeling your best. Plans are flexible, and can be canceled or changed at any time.
