“At Fred Hutch, I belong to a family of innovative, patient-centered providers.”

— Dr. Grivas

What drew you to oncology?

Ever since I was young, I’ve wanted to help other people. I knew a family friend who was a physician, and he served as a great example of how I could channel this desire, combining knowledge and compassion so that I could be of service to a community. I chose to focus on genitourinary cancers because they’re a set of very common diseases affecting the urinary tract and male reproductive system, so I felt pursuing this specialty would allow me to make a difference in the lives of many. I see this area of oncology as an opportunity to bring together my interest in innovative research and patient care.

How do you like to work with patients?

I am dedicated to providing outstanding cancer care, which to me means taking a personalized approach with each patient and being efficient with time and resources. I hope to learn what brought you in and what your goals and expectations are — both for each visit and in the long term. While I bring a wealth of knowledge about genitourinary cancers and the latest research developments, I also believe that the little things, like a warm smile and a conversation held eye-to-eye, matter a great deal.

Genitourinary cancers

I am a board-certified medical oncologist who specializes in treating patients with genitourinary cancers, such as bladder cancer and prostate cancer. My background includes leading the bladder/urothelial cancer program at the Cleveland Clinic and caring for patients at the University of Michigan, Ann Arbor. Currently, I serve as the director of UW Medicine's Genitourinary Cancers Program, giving frequent lectures, educating other oncologists and trainees and publishing novel research. I also conduct clinical trials, one of which led to the FDA approval of new drugs for bladder and urothelial cancer. I also co-host our annual event on Updates in Bladder and Urinary Tract Cancers for Patients and their Loved Ones.
