Our Functional Medicine 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.

Dr Miles' Story:
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 "something has happened with your father and you 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. Then in my 20's I personally suffered from chronic fatigue. I remember being called into Valerie's office. Valerie was the president for the medical school I was attending. She said that although I was doing well academically, being late for my first class of the day was endangering my ability to get through medical school. I told her that I was really trying as hard as I could to get up and get going, but even if I got 8, 9, or even 10 hours of sleep I was still dragging in the mornings and even into the afternoon. She said something might be medically wrong. I told her that I had been to a conventional doctor and they had said everything looked fine. She encouraged me to seek additional medical help.

I spent many years seeing every specialist I could think of: naturopaths, acupuncturists, chiropractors, integrative MDs, energy healers, and more. Eventually I discovered a functional medicine mentor and was able to test myself for underlying root cause issues. I found a subclinical thyroid issue, autoimmune antibody, multisusceptible mold illness genetics with exposure to black mold, gut infections, sleep apnea, and chronic Lyme co-infections Babesia and Bartonella. I was able to recover my energy after treating these main root cause issues through functional medicine protocols. It was a difficult journey, and I have made it my mission to help other have something I never had: a step-by-step guided process through identifying root causes and reversing them, naturally when possible.

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 functional medicine has saved my life and it inspired me to use my education and experience to do the same for others.

Growing up in a large Italian family, food represented love and friendship, and the way to celebrate social occasions and holidays. My family gathered often to share large home cooked meals. I started cooking at age 11 and my grandmother taught me how to make pasta, bread, and desserts to share. Throughout childhood and into my early adult life, food became the way to manage my stress and find comfort, and I ate lots of carbs and sugary foods, gaining weight. After college, I was working in the field of investment banking and was eating out often, making unhealthy choices, and became more overweight. I was working all the time in a stressful job, not seeing friends, or pursuing any hobbies - my life was unfulfilling. In the meantime, several of my beloved family members died at young ages due to food related diseases. I began to realize I had an unhealthy relationship with food, and that it might be the reason I didn’t feel good, sleep well, or have energy. It was at that point that I decided to make diet and lifestyle changes to feel better, manage my stress, lose weight, and to live a longer and happier life. I became passionate about being healthy and then decided to become a nutritionist. 

I enrolled in the Certified Nutrition Consulting program at Bauman College. As a student there, what I was most intrigued about was learning that food could help manage health conditions. Although skeptical at first, I decided to try out what I was learning about for my own health conditions. I had hypothyroidism, was on a thyroid medicine, my cholesterol was high, and I was always tired. I changed my diet and ate foods that supported my conditions. In a very short time, I was no longer on any medicine, and my cholesterol was in a normal range. For the first time in many years, I felt great and had lots of energy. I even climbed my first Fourteener in Colorado! I was eating to live and not living to eat! 

Since then, Lynn has made it her life’s mission to help others understand that to “Eat Well is to Live Well”. The guiding principle underlying her work is to provide nutrition education, coaching, and support with compassion to empower others to make dietary and lifestyle changes to be able to live the life they want with gratitude. In her spare time, Lynn stays fit through Jazzercise and enjoys going hiking, biking, cross country skiing, and snowshoeing. She has two children and takes great pleasure in traveling and exploring with her family.
