Dr. Kate Kass

Dr. Kate Kass founded Kass Precision Medicine in Bellevue, WA and serves as its sole physician. She specializes in men's and women's hormone health, menopause, evidence-based hormone replacement therapy, sexual health, and metabolic syndrome. Dr. Kass grounds her practice in functional medicine, treating whole systems rather than isolated symptoms.

She holds a pioneering position in shockwave therapy for erectile dysfunction. Dr. Kass was one of only two doctors in the United States to pilot the GAINSWave program, working alongside Dr. Gaines from the beginning. She brought the therapy to the West Coast first, and her practice has since performed more shockwave procedures than any other clinic in Washington State. National outlets including The Dave Asprey Podcast and the New York Post have featured her work. Patients describe Dr. Kass as thorough, unhurried, and genuinely invested in finding long-term solutions over quick fixes.
