Each of us can be viewed as an open, complex, and integrated system that has various layers: physical, energetic, mental/emotional, intuitive, and spiritual. Therefore, each patient is unique and requires individualized biological and emotional support.  I use a combination of Biological Medicine, Integrative and Functional Medicine to provide compassionate care to those who are suffering from chronic illness and/or to help others reach their fullest potential.  I have had the great good fortune of learning from many great Integrative/Functional and Holistic doctors around the country and around the world. The following highlights my experience:


Certified by the American Board of Anti-Aging and Regenerative Medicine (A4M)

Certified in Autonomic Response Testing (ART)

It is an honor to be certified in Autonomic Response Testing (ART) with Dr. Klinghardt, MD, Ph.D. Autonomic Response Testing is an advanced form of biofeedback that gives us deep insight not only into the root cause of illness but how to effectively treat it.  Dr. Mercola, MD also agrees and has found this technique to be invaluable in his practice. For more information, see this link.

Certified in Mitochondrial and Anti-Aging Medicine

It is an honor to be certified in Mitochondrial Wellness with Dr. Kucera, MD,  a genius of his time, who, in the process of assisting the Russian Cosmonauts to adapt to the stresses of space travel,  devised a novel way to not only support the mitochondria, the powerhouses of all our cells but to measure this process using an advanced Heart Rate Variability Testing.

My Personal Health Journey...

Quest for the Crest 50K Race, NC, 2014

I have always been an athlete and had enjoyed great health up until college. All of the sudden, I began to experience fatigue, insomnia, anxiety, and irritability. My insomnia was debilitating and persisted despite counseling, meditation, yoga, diet, and other interventions. I had engaged multiple doctors, herbalists, and acupuncturists to no avail. I just couldn't sleep. I finally gave up and tried a number of antidepressants and sleeping pills, but was often left feeling sedated. It wasn't until after doing extensive research that I found that my Mercury amalgams might be the culprit. It made sense--my health declined dramatically after I had dental work done. I mentioned this to my Doctor and he reluctantly agreed to test my blood for Mercury. After my blood test came back negative, my research and intuition led me to the decision to have my fillings removed by a local Holistic dentist. Just mere weeks after removing my amalgams, my anxiety started to fade, my sleep improved and my well-being returned.

It was a long, 10-year journey, but I felt like I had gotten my life back.

This journey compelled me to investigate the world of functional, integrative, and holistic medicine. I was further compelled on my journey by my many friends and relatives who, just like me, had experienced seemly mysterious health conditions that were left unanswered by the conventional medicine approach, with health conditions ranging from: anxiety, joint pain, headaches, stomach problems, and so forth, to more complex conditions like auto-immune disease and Parkinson's Disease.

This set me on a path to find a way to truly heal people, not just treat their symptoms. My reward is seeing my patients' quality of life improve.


We work with many great functional laboratories around the country. Here is just a partial list:
