From Doctor to Empowered Patient

I’ve always been interested in alternative medicine. I chose osteopathic over allopathic medical school because of the additional training in manipulative medicine. I sought out a preventative medicine residency and a master’s degree in public health because of my desire to help individuals and communities engage in their health outcomes. I also served as a consultant for the Department of Defense for the University of Arizona’s Fellowship in Integrative Medicine. Previously, my master’s degree in biotechnology provided me with a solid background in scientific research and laboratory skills.

My time in emergency and military medicine taught me the best of western medicine – treating acute injuries and illnesses. When I found myself in the role of the patient, however, my own profession failed to provide me with anything but life-long prescription medications and a worsening prognosis over time.

I first noticed subtle neurological symptoms in 2012 when, under immense stress while searching for my lost dog, a friend noticed my arm swing was diminished. Next came slurred words and inconsistent snowboard steering. Multiple neurologists told me everything was normal even though my body was clearly changing.

Eventually, I was diagnosed with Parkinsonism due to the atypical nature of my symptoms. I continued to seek out specialists but none of them were able to tell me why in my mid 40’s, I had to give up trail running, Spartan Races, snowboarding, and hikes with friends and our dogs… or offer any hope for improvement. Of the multiple movement specialists that evaluated me, not one of them mentioned toxins, Lyme, or mold as known and potentially reversible causes of Parkinson’s.

My interest in alternative medicine was reignited and I took an even deeper dive into Functional Medicine.

I changed my diet to Autoimmune Paleo, corrected nutrient imbalances, treated gut infections, removed mold, addressed Lyme, made detox an everyday habit, and addressed my mental-emotional-spiritual health with a daily meditation practice. I did something that none of my neurologists had thought possible. I changed the course of my prognosis.

Now that the underlying causes of my symptoms have been addressed, I have entered the repair and regeneration phase and I can see a 5k in my future. Through my experiences, both as a physician and a patient, I now know there is always opportunity for transformation. I am always on the lookout for new and cutting-edge therapies.

It is my mission to help others utilize Functional and Integrative Medicine principals to prevent, halt, and even reverse symptoms and disease.
