Medical Oncology

“I want to treat all my patients as if they were my own family, which means providing whatever emotional, physical and mental support they need.”

— Siri

What do you value about your work?

A patient once thanked me for being her “elephant.” She then told me a story of love and loyalty:

“In the wild, female elephants are known as fierce protectors. And when one of their sisters is suffering, they circle up around her. They close in tight, stand guard and even kick dust around her to mask her vulnerable scent from predators. 

We are the same. This is who we are and who we are meant to be for each other. Sometimes we are the ones in the middle. Sometimes we are the ones kicking up dust with fierce, fierce love. But the circle remains.”

Little did she know, elephants are my favorite animal. I will never forget her kind words and story. 

What is your approach to providing care?

I’m a happy person. The glass is always half full rather than half empty. Despite the need to sometimes pass along bad news, I also want to share in the hope about the options available to patients today. My goal is to build a relationship with patients so they can trust me to help empower them. We can take it one step at a time, together.

Provider Background

Area of Clinical Practice
General medical oncology, benign and malignant hematology

I am an advanced registered nurse practitioner who sees patients at Fred Hutch at Overlake Clinic.

I have been involved in numerous clinical trials as a sub-investigator. I helped actively identify and recruit patients for trials, guiding them and helping to decide if clinical trials made sense during this part of their cancer care. During a trial, we discussed any side effects, and I helped to manage them. I have also participated in financial toxicity programs, which help patients participate in trials without having to worry about how they can afford it or how to get to the cancer center. 

Community Oncology 

Our mission is to provide patients with the highest quality, personalized care closer to home. As part of Fred Hutch, our community oncologists offer patients multidisciplinary tumor board opinions, clinical trials and expertise in treating a variety of cancers.

Clinical Trials

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

Your Care Team

At Fred Hutch, you receive care from a team of providers with extensive experience in your disease. Your team includes physicians, a patient care coordinator, a registered nurse, an advanced practice provider and others, based on your needs. You also have access to experts like registered dietitians, social workers, acupuncturists, psychiatrists and more who specialize in supporting people with cancer or blood disorders.


Fred Hutch accepts most national private health insurance plans as well as Medicare. We also accept Medicaid for people from Washington, Alaska, Montana and Idaho. We are working to ensure that everyone, no matter what their financial situation, has access to the care they need.
