Kass Precision Medicine teams with patients to adopt key strategies for sustained weight management. We understand that there is no magic bullet - weight fluctuations happen. We aim to arm patients with lifelong tools to help them stay sane and healthy. KPM harnesses best-in-class medications like Ozempic and Mounjaro to help patients achieve their weight loss goals.

Over the past two decades, attitudes towards hormone replacement therapy have evolved. Today we have clearer distinctions between hormone types, routes, and timing. At KPM, we emphasize evidence-guided hormone therapy using bioidentical formulations. In appropriate candidates, HRT can improve symptoms of menopause and quality of life.

“I've been seeing Dr. Kass for many years now after seeing other doctors with little results. All visits and treatments have been excellent. She and her staff are very friendly and knowledgeable. She is very thorough and covers everything. I've been happy with all the treatment I've received and found them to be highly effective. She is definitely the best in her field in the Seattle area, and I've always been impressed with how her approach and knowledge are ahead of the curve.”

“Dr. Kass was the first to truly listen. She took my lingering symptoms seriously - fatigue, brain fog, weight management - and looked deeper instead of telling me everything was “normal.” She addressed my perimenopausal symptoms in a way that I felt like my primary care didn't have the tools to assist with.”

– Cici N. - Age 39

“The best all-around doctor I have ever had. Her entire staff I have encountered are proactive, highly competent and transparent. Dr Kass' team has the patient's best interests foremost and my experience has already been life-changing. The medical care is much deeper than merely treating any one issue. My overall health has improved.”

– Jeff V. - Age 58

“Dr. Kass is the ultimate professional. Practical, straightforward, knowledgeable and very kind. Dr. Kass is up to date on all of the latest, but doesn't get swayed by the "newest and greatest thing." She knows all of the research and benefits behind the services that she offers and takes the time to explain it. I couldn't be happier with my experiences with Dr. Kass, she is truly my trusted medical advisor.”

“Dr. Kate Kass’ treatment for ED has changed my life in so many ways as a 60 year old man. She took the time to understand my needs and put me on a great treatment plan very affordable. The results are amazing. I recommend anyone to go to her for any ED issues in your life.”

– Lawrence D. - Age 62

“Dr. Kass and her team are phenomenal. I am impressed by her level of knowledge and she has a holistic approach. I could not ask for a better level of service and care.”

– Cydney B. - Age 50

“I highly recommend this practice to anyone going through changes with aging, especially men around my age. The level of openness and availability from the team really stands out—they take the time to listen and make you feel comfortable discussing anything. The office staff is incredibly kind and welcoming, which makes every visit a positive experience. I truly have nothing but good things to say about this practice.” 

Vishnu N. - Age 44

“After battling breast cancer with a BRCA-1 diagnosis in my thirties, I experienced early surgically induced pre-menopause for over a decade. During my first consultation with Dr. Kass, she confirmed that HRT would be beneficial based on my symptoms and test results. Dr. Kass provided personalized hormone replacement therapy (HRT) that has led to significant improvements in my sleep, reduced irritability, weight loss, and enhanced bone density.”
