Dr. Lisa Parsons


Medical Director

Bio +

Dr. Parsons knew from a young age that she would one day become a doctor. She received her Bachelor
of Arts in Psychology from Florida Atlantic University where she graduated summa cum laude. She went
to Medical School at Wayne State University in Detroit Michigan. Next was her Internship and
Psychiatric Residency at Banner Good Samaritan Hospital in Phoenix Arizona. Dr. Parsons went on to
work at Banner Thunderbird Hospital doing Consult Liaison work on the medical floors, in the ER and
psychiatric ER, as well as working on the inpatient psychiatric unit. She them moved to Prescott Arizona
and became Medical Director at a large community mental health center called West Yavapai Guidance

The experience obtained through those years brought her to the awareness that Psychiatric illness
including addiction are much more than brain disorders and treatment needs to include the whole
person. In fact, sometimes the originating imbalance isn’t located in the brain at all. This lead her on a
quest to understand whole body causes of psychiatric symptoms and search for holistic treatments for
the originating problem. She received certification from ‘Integrative Medicine for Mental Health’ and
has continued to expand her knowledge with them. She has collaborated with colleagues in the
community and across the country that are experienced in Integrative Medicine as well. She has
received certification in Functional Medicine approaches to treatment through the ‘Integrative Medicine
Academy’. Most recently she was certified by ‘The Wash Research Institute’ in Nutritional Medicine.

This experience has led to her to a treatment style of combining Western Medicine, Eastern Medicine,
Functional Medicine and Nutritional Medicine approaches to alleviate psychiatric symptoms and

As her understanding of these effective approaches expands, her potential to help people create
positive change in their lives has grown as well. This enriched treatment repertoire has strengthened her
fund of knowledge and deepened her gratitude for being a part of positive change.
