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.

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.”

“Healing is an individual journey. Healing happens on the mental, emotional, and physical level. Healing is the journey towards better balance. We all have a myriad of things that determine our current health; our genetics, environment and health history as well as your lifestyle and diet history determine your health. Healing is working towards a life with less pain, less stress reactivity, better lab markers and certainly feeling better energy and more joy.”
