Better health. One case at a time. Doctor led care from Integrative and Functional MDs.

What is Integrative and Functional Medicine?

Integrative Health: The Medicine Of "Why?"

6/10 Americans are fighting chronic conditions – issues that can’t be solved by masking the symptoms with pills.


To create health, our Integrative MDs dig underneath your symptoms to uncover why you aren’t feeling well.

Once we know why you are sick, we can fix the problem at its root using a whole-body approach: lifestyle and supplement recommendations mixed with conventional medical therapies.

Why Integrative MDs?

Integrative MDs: Super Generalists 

After achieving Board Certification in a conventional medical specialty, Integrative MDs (and DOs) undergo additional sub-specialty training – connecting body-systems together into a cohesive whole human.  

Integrative MDs emerge with the broadest toolkit in medicine; the ability to leverage: 

  • Conventional tests and drugs 

  • Evidence-based alternatives  

  • Referrals to sub-specialty MDs and alternative practitioners   



You can’t expect to fix a chronic issue in 15 minutes. CIH appointments are

30--90 minutes: giving you time to dig deeply.  

Root Cause

Finding the core issue is the only way to truly heal. This means tracing symptoms across all mind-body systems to find the root.
