The Skilled Doctors at Medicine With Heart Functional Medicine Clinic

Dr. Diane Mueller

ND, DAOM, LAc, Functional Medicine

My journey into the health care field was born out of my own personal health struggles. Having 20 plus years of constipation, bloating, chronic fatigue, headaches, brain fog and fibromyalgia, yet normal conventional lab work, modern medicine had no place for me. Despite all of this, I believed in my heart it was not right to feel the way I did and thus began a journey of self-discovery, into the world of holistic medicine.

I fell in love with the world of naturopathic medicine. Fueled by this love, together with a deep desire to help others and myself, I finished a doctorate in Naturopathic Medicine and a Masters degree in Acupuncture. Since this, I have worked to earn a second doctorate in Acupuncture and Oriental Medicine, a certificate in qigong (mindfulness practice), a certificate in applied kinesiology and countless hours studying Functional Medicine and Lyme disease with some of the most pristine doctors around the country.

As I applied what I studied to my own life, I discovered that main physical root causes of my health struggles included multiple gastrointestinal infections, liver detoxification issues and chronic Lyme disease. On my journey, I also learned that I had a deep inability to handle stress, tendency to become overwhelmed and a difficulty letting go past hurts.It was when I began to combine all of the treatments for the body, with a new approach for working with my mind that I truly experienced amazing results. These experiences helped me to understand that in working with both the mind and the body, do we get the best healing.

My most typical patient has been to several practitioners before, often with making small gains, but without finding the true root of their issue. Common symptoms I work with are autoimmune disorders, fibromyalgia, chronic fatigue, and digestive complaints. Through lab testing, it is not uncommon to find Lyme or other chronic infections as part of the root cause. Together we work to address both the mind and the body to help you heal from the inside out. In addition, you will receive an education that will aid you with tools to help continue wellness and prevent disease. 

In health and with love,
Dr. Diane

Dr. Miles Nichols

“My father was an MD and a state senator. He helped many thousands of underprivileged people to gain access to resources. He spearheaded a piece of legislation called “Healthy Arizona Initiative” that took lottery and tobacco tax money and made it available to people who fell below the poverty line but were ineligible for welfare. I saw and was inspired my fathers immense service and impact in the world.

When I was 15 years old, my father passed on suddenly and unexpectedly from a heart attack. This shock and my experience around his death caused me to become very curious about health and psychology. Though my father had top notch medical training from Stanford, and a Masters in Public Health from Yale, he passed on without any warning at the age of 64. He was a high-performer with a busy life. He was at the pinnacle of his career, and I know that if he had lived many more years, he could have touched hundreds of thousands if not millions more lives.

I became completely devoted at this time to learning about preventative healthcare, nutrition, and mindfulness practices as ways to cope with my loss and to make sure that I do everything I can to help myself and others to live long, healthy, happy lives. I am deeply inspired by offering treatments and educational materials that teach people to transform their lives. My primary goal when working with people is to empower clients with practical action-steps to implement with regards to nutrition, lifestyle, supplements, and mindfulness practices.”

In health and with love,
Dr. Miles
