Our Approach

Digging Deeper

Life is meant to be enjoyed and health is an essential ingredient. We help our patients resolve chronic conditions that keep them from living their best life. We get to know the person and invest time to get to the root cause(s) of health issues.

Advanced Testing

Functional Medicine is an integrative, science-based approach that focuses on overcoming and preventing chronic illness by addressing root causes. Our innovative testing discovers what prevents patients from reaching optimal health.


Our visits are collaborative. We utilize a team approach to come up with a treatment plan that works best for you. Patients have direct access to practitioners via an online patient portal.

Personalized Roadmap

All of our protocols are individualized based on unique health history, genetics and environment. Protocols include a personalized dietary plan, lifestyle changes and targeted supplements and nutraceuticals.

"…this is the first time in my life I was able to discuss my health issues for more than 10 minutes. If you are really serious about fixing a health issue and you are not getting help from your doctors, try talking to Dr. Moday. And if the only solution your doctor has to a problem is drugs, try talking to Dr. Moday."
