“I believe that education is empowerment. By taking into consideration all factors when caring for a patient, I believe explaining options for treatment and encouraging patients to take an active role in their healthcare will allow them to be stronger and more confident in achieving optimal wellness.”

Why do you practice oncology?

As a child I was always been fascinated by medicine and how the human body works. It is one of the most intricate, resilient and complex organisms on the planet and still ceases to amaze me every day. Everyone has been affected by cancer whether it be a friend, family member or from a personal encounter. Working with cancer is a complex, ongoing battle that we are continually trying to fight with new medications and therapies. After my dad was diagnosed with cancer, I wanted to be on the forefront of innovation and excellence in finding a cure. Outside of work, I love exploring and spending time right here in my home of the Pacific Northwest!

Clinical trials

We make promising new treatments available to you through studies called clinical trials led by SCCA doctors. Many of these trials at SCCA 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.

Your team includes doctors, a team coordinator, a registered nurse, an advanced practice provider and others, based on your needs. You also have access to experts like nutritionists, social workers, acupuncturists, psychiatrists and more who specialize in supporting people with cancer or blood disorders.
