Why should a patient trust Fred Hutch for care?

A patient who chooses Fred Hutch can be confident they are being evaluated by the best of the best. Our patients receive the most up-to-date and evidence-based care in a highly compassionate place.

How would you describe your approach to care?

My approach is highly patient-centered — the patient always has priority. I try to combine the latest medicine with a kind and caring approach. My goal is for my patients to leave feeling completely comfortable with their care and with no questions left unanswered.

Because screening may find diseases at an early stage, there may be a better chance of curing the disease. Examples of cancer screening tests are the mammogram (for breast cancer), colonoscopy (for colon cancer) and Pap and HPV tests (for cervical cancer). Screening can also include a genetic test to check for a person’s risk of developing an inherited disease.

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.


Many of our Fred Hutch doctors conduct ongoing research to improve standards of patient care. Their work is evaluated by other doctors and selected for publication to the United States National Library of Medicine, the largest medical library in the world.
