“At SCCA, 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.

Provider background

Specialty: Medical Oncology

Area of clinical practice

Genitourinary cancers

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.

New data on risks and treatment for patients with cancer and COVID
New data on risks and treatment for patients with cancer and COVID

Since the COVID-19 pandemic began, oncologists have grappled with questions about potential risks and treatment changes for their cancer patients. To address these and many other questions, Seattle Cancer Care Alliance (SCCA) partnered with Fred Hutch, Vanderbilt University and other organizations to form the COVID-19 Cancer Consortium (CCC19).


Clinical trials

We make promising new treatments available to you through studies called clinical trials led by Fred Hutch doctors. Many of these trials at Fred Hutch have led to FDA-approved treatments and have improved standards of care globally. Together, you and your doctor can decide if a study is right for you.
