About Kass Precision Medicine

Kass Precision Medicine is a concierge practice in Bellevue, WA  led by Dr. Kate Kass and an experienced team of providers.

We address a broad range of acute and chronic conditions, specializing in men’s and women’s hormone health, menopause, evidence-based hormone replacement, sexual health and erectile dysfunction, and treating metabolic syndrome. 

Kass Precision Medicine believes in a paradigm of medicine that eschews the “one symptom - one drug” approach in exchange for a more precise practice dedicated to a deep dive. Each patient’s unique constellation of symptoms, genetics, and environmental factors guide treatment at KPM.

“HEALTH IS A STATE OF COMPLETE PHYSICAL, MENTAL, AND SOCIAL WELL-BEING AND NOT MERELY THE ABSENCE OF DISEASE OR INFIRMITY.”

A PRACTICE GROUNDED IN THE PATIENT EXPERIENCE AND PRECISION MEDICINE

Dr. Kass and her medical team partner with our patients to get a comprehensive health picture so we can understand the unique environmental, genetic, and lifestyle factors that contribute to your health trajectory.

Kass Precision Medicine is passionate about finding the most up-to-date solutions for our patients. Patients will receive progressive, evidence-based, and personalized treatments that assist in slowing the diseases of aging and extending vitality.
