Functional Wellness Programs For Whole-Body Healing

Santa Cruz and Beyond


Optimal Wellness

Vibrant Energy

Healthy Future

Are you dissatisfied with the results you’ve gotten from conventional medicine?

Has your doctor said that your labs are normal, but you still don’t feel well?

Are you ready for a solution to end your pain and discomfort?

Unfortunately, the acute-care approach to medicine is poorly designed to address chronic fatigue, autoimmunity, and other complex conditions.

Most Western medical practices do not account for the unique genetic makeup of each individual or how modern lifestyle has influenced the rise of chronic disease in our society.  Most doctors simply don’t have enough time to figure out the root causes and teach their patients how to be healthy.

I believe that everyone has unlimited potential to overcome their health challenges and live their most purposeful life.
