Director & Integrative Doctor

Denise Cooluris, N.D.

A Bastyr University Seattle alumna and adjunct professor, Hill Park Medical Director and owner Dr. Denise Cooluris represents 10+ years of experience in the field. Serving a variety of roles in the integrative medical field as a local and national speaker, mentor, and writer, especially in the areas of women’s health, naturopathic family medicine, and herbal medicine, Denise offers integrative family medical care with specialized interest in natural gynecology, oncology, and chronic illness. In addition as a naturopathic doctor, she asserts a variety of treatment offerings, rich in real science and traditional wisdom.
“If I were to choose one therapy that works finest above all others, it would be to listen. All patients deserve to have their health concerns heard and respected by a knowledgeable doctor. In addition, the body speaks clearly when it is imbalanced, from a whisper of mild concern, to a scream of serious illness.”

Integrative Holistic Physician

Lois C. Johnson, M.D.

With 30 years of experience combining alternative and herbal medicine with the best of conventional medical care, Dr. Lois Johnson is an integrative holistic physician with board certification in Internal Medicine. Her specialties include oncology, complex and multiple diagnoses, women’s health issues, bio-identical hormones, chronic fatigue, fibromyalgia, hepatitis C, and Lyme disease.
“The healing journey always involves a story. When I really hear the story, solutions often become visible. My personal passions for art, poetry, and nature inform my work on a daily basis. My own experience as a cancer survivor has deepened not only my empathy but my practical knowledge of what people really need during difficult times. I appreciate the truth and beauty of the human experience with all its joys and sorrows, in times of new growth and in times of letting go that make up the cycle of life.”

Men’s Health, Urology, and Nephrology

Eric Yarnell, N.D.

Eric Yarnell, ND, RH(AHG) (Bastyr University, 1996) is a researcher and professor at Bastyr University and has been in practice for 25 years, focusing on solutions to men’s health, urology, and kidney problems, with a heavy emphasis on herbal medicines. Dr. Yarnell works to find the underlying causes of conditions and to use whatever tools are needed (preferably natural ones, saving conventional approaches only for those few cases where they are truly necessary) to support healing. Dr. Yarnell is chief creative officer of Wild Brilliance Press, president of Heron Botanicals, and CEO of Red Root Pharmaceuticals. He is a co-founder of the Boucher Institute of Naturopathic Medicine in Vancouver, BC. He previously served as chair of the department of botanical medicine at the Southwest College of Naturopathic Medicine. He has over 150 published medical articles and is the author of many of the definitive textbooks used to teach naturopathic doctors including Natural Approach to Urology 2nd ed, Natural Approach to Prostate Conditions 2nd ed, Natural Approach to Gastroenterology 2nd ed, and the forthcoming Naturopathic Nephrology.
“Nothing is more satisfying than really listening to someone’s whole story, and helping them discover and fix the underlying cause of their problem.”

General Integrative Doctor

Michaela Falkner, N.D.

After completing her degree program from Southwest College of Naturopathic Medicine in Tempe, Arizona, Michaela was selected as one of five national candidates to complete a prestigious general medicine residency at SCNM. During both her degree program and residency, she focused much of her education on caring for complex cases and autoimmune diseases. Dr. Falkner often takes a multipronged approach in healing the gastrointestinal system, modulating the immune system, and symptom management. She also is certified in IV therapies and microneedling facial treatments and holds licenses in both California and Arizona.
“Good medicine is not only effective, but understandable and whole body focused. Treatment plans should address the whole person and give a sense of control and understanding of the body’s processes. The body is truly resilient if given the tools it needs. As a doctor, my role is to teach and guide the body gently back towards a state of health.”
