About
Naturopathic Physician
She/her
Dr. Ksenia Malarkey is a licensed naturopathic physician in Washington State with a deep commitment to whole-person healing. A graduate of Bastyr University, she completed a two-year integrative oncology residency at the AIMS Institute in Seattle. She offers virtual consultations for both in-state (telehealth) and out-of-state (tele-education) patients.
Dr. Malarkey’s clinical focus includes integrative oncology, complex chronic illness, hormone and metabolic health (including biHRT), autoimmune conditions, digestive health, and mental wellness. She blends traditional wisdom with modern science, using naturopathic and evidence-based approaches to support healing on the physical, emotional, and spiritual levels—helping patients cultivate lasting balance, resilience, and vitality.
Originally from St. Petersburg, Russia, Dr. Malarkey learned about health through the lens of environments from a young age. Summers were spent foraging mushrooms, berries, and herbs under the guidance of her grandmother. Those teachings laid the foundation for Dr. Malarkey’s belief in the importance of holistic care and “vis medicatrix naturae” (the healing power of nature).
In addition to her clinical work, Dr. Malarkey is the author of Integrative Oncology Insights, a Substack publication exploring the intersections of cancer care, metabolic health, and the art of healing. Through her writing, she brings complex science to life, empowering readers to engage with their health through curiosity, context, and connection.
Outside the clinic, she finds joy in movement, time outdoors, and building community.
