Our Clinical Team

Dr. Miles Nichols, DAOM, MSOM, LAc is the co-founder of Medicine With Heart Clinic and the Medicine With Heart Institute. Dr. Miles is married to the co-founder of these organizations, Dr. Diane Mueller.

Growing up, my father was a medical doctor focusing on public health. He was a kind, generous, and patient man. I do not remember him yelling even once in my life. He also changed the world. He founded a rural health office that took mobile clinics and sent them to rural areas for basic check-ups for people who did not have good access to healthcare. He became a State Legislator and then later a State Senator. He worked tirelessly to pass legislation that would give access to healthcare to the working poor.

One day while I was babysitting for a friend of my sister, I got a call from a family friend. She told me that something has happened with my father and I need to go to the hospital right away. My father had passed away suddenly and unexpectedly from a heart attack. I was 15 years old at the time.

This tragic event threw me for a loop. My father had top-notch medical training from Stanford Medical School and Yale Public Health program. However, my family did not see this coming. There was no warning. I began to investigate and learned that while his medical training was the best offered at the time, nutrition, mindfulness, and functional medicine were not covered. I learned that according to the CDC about 6 in 10 American adults have at least one chronic disease. This rate is growing (not getting better). My response to this event was to dedicate my life to learning everything I could about a new way of practicing medicine to help to prevent and reverse chronic illness. This plunged me into studying everything I could in medicine and helped me to recover from the extreme chronic fatigue I had which turned out to be from mold genetics, bartonella and babesia.

I completed my undergrad at California Polytechnic State University on the central coast of California in 2009, and continued my education which led me to healthcare.

After working in several different specialties of allopathic medicine as a nurse (RN), I found a love for natural medicine and have chosen to devote my educational background and healthcare experience to inspire people to be more intentional with their wellness. I have lived in Littleton, Co for 3 years with my partner, Dane, and our 3 dogs - Ajax, Jojo and Twailey.

My health journey has been a rough one. While completing my undergraduate degree I fell incredibly ill. For 3 months, I felt what I assumed was the worst flu in my life. Every muscle in my body hurt all day, every day. Then, for the next 2 years, my joints would unexpectedly lock up, especially in my fingers and hands, making it almost impossible to get anything done without struggle. After being referred to a rheumatologist, I was given the diagnosis of Systemic Lupus with an arsenal of prescriptions - steroids, immuno-suppressants, opioids, motility drugs, anti-psychotic drugs, and that was just the beginning. My health diminishing day by day and that took a very big tole on my mental well being. I feared that being in pain was my lifelong curse, and the only way to be out of pain would be to end my life.

A failed suicide attempt left me searching for answers. I began learning about holistic health, integrative nutrition and functional medicine. With a "what do I have to lose" attitude - I began changing my nutrition and fitness routine - and noticeably felt better. After that, I buried my face in books to learn about nutraceuticals vs pharmaceuticals and the difference they made in the human body. I made the switch to a complete, WHOLE wellness, lifestyle and within a year and a half had improved every one of my symptoms. Seeking, perusing and sticking with natural medicine has saved my life and it inspired me to use my education and experience to do the same for others.
