Ksenia Malarkey, ND

​​

Dr. Ksenia Malarkey is a licensed naturopathic physician in Washington State specializing in integrative oncology, functional medicine, hormone optimization, chronic disease management, and personalized precision medicine. She earned her Doctor of Naturopathic Medicine degree from Bastyr University and completed a prestigious two-year Integrative Oncology Residency at the AIMS Institute in Seattle.

​

Dr. Malarkey provides virtual naturopathic consultations throughout Washington via telehealth, as well as tele-education services for patients outside Washington State, making expert integrative care more accessible regardless of location.

​

Her clinical practice focuses on helping patients address the root causes of illness through evidence-based naturopathic medicine. She works with individuals facing:

• Integrative cancer care and cancer survivorship

• Complex chronic illness

• Bioidentical hormone replacement therapy (BHRT/biHRT)

• Thyroid, adrenal, and metabolic disorders

• Autoimmune diseases

• Digestive disorders and gut microbiome imbalances

• Chronic fatigue and mitochondrial dysfunction

• Mental health, stress resilience, and cognitive wellness

• Preventive medicine, longevity, and healthy aging

​

Dr. Malarkey combines modern scientific research with traditional naturopathic principles to create highly personalized treatment plans that support healing on the physical, emotional, and spiritual levels. Her philosophy is rooted in Vis Medicatrix Naturae—the healing power of nature—while integrating advanced laboratory testing, nutritional medicine, lifestyle interventions, botanical medicine, and precision therapeutics.

​

Originally from St. Petersburg, Russia, Dr. Malarkey developed a deep appreciation for natural medicine at an early age. Summers spent foraging wild mushrooms, berries, and medicinal herbs alongside her grandmother inspired a lifelong passion for botanical medicine, environmental health, and whole-person healing.

​

In addition to clinical practice, Dr. Malarkey is the author of Integrative Oncology Insights, a publication dedicated to helping patients better understand cancer biology, metabolic health, functional medicine, longevity, and the science of healing. Through thoughtful education, she empowers readers to make informed decisions about their health with clarity, confidence, and compassion.

​

When she is not caring for patients, Dr. Malarkey enjoys hiking, movement, spending time in nature, writing, and building meaningful community connections.

Specialty & Functional Medicine Testing

 

Dr. Malarkey uses advanced functional and precision-medicine testing to identify the root causes of illness and imbalance, then builds individualized treatment plans around what the data actually shows. Testing is selected individually and may include, but is not limited to, the following.

​

Integrative Oncology & Immune Health

• Liquid biopsy (ctDNA, CTC) for early detection, treatment monitoring, and minimal residual disease (Signatera, Guardant, NorthStar)

• Tumor genomic profiling (FoundationOne, Tempus) and multi-cancer early detection (Galleri)

• Chemosensitivity testing (RGCC)

• Tumor and immune marker panels

• Genetic, epigenetic, and pharmacogenomic testing

• Autoimmune and inflammatory screening

​

Hormone & Metabolic Health

• Comprehensive sex hormone, adrenal, and cortisol rhythm testing

• Full thyroid assessment with antibodies

• Bioidentical hormone optimization (saliva, urine, and serum)

• Fertility and ovarian reserve testing

• Cardiometabolic and insulin resistance panels

• Advanced cardiovascular risk (ApoB, Lp(a))

• Advanced micronutrient and fatty acid testing

• Bone health (DEXA, bone turnover markers)

​

Digestive & Microbiome Health

• Comprehensive stool and microbiome sequencing

• Gut barrier integrity markers

• Food sensitivity and allergy testing

• Parasite, candida, and dysbiosis evaluation

​

Environmental & Detoxification Health

• Mycotoxin and mold exposure testing

• Heavy metal and chemical toxin panels

• Detoxification and antioxidant status

​

Longevity, Stress & Circadian Health

• Epigenetic biological age and methylation profiling

• Neuroendocrine and stress-axis evaluation

• Cognitive and neuroinflammatory markers

• Sleep-wake and circadian rhythm assessment

​

By integrating advanced diagnostic testing with naturopathic medicine, functional medicine, nutrition, lifestyle medicine, and evidence-based therapies, Dr. Malarkey develops personalized treatment plans designed to optimize health, enhance resilience, support recovery, and promote long-term wellness.
