Why do you specialize in infectious diseases?

I’ve always wanted to make a difference in the lives of others, and ever since I first began my journey in health care, I have found infectious disease fascinating. Each infectious disease consultation allows me to get to know a patient in a meaningful way. Understanding who they are as a whole person, and what their lives are like, helps me assess any risk factors and consider how to best protect them during treatment. I’m grateful for the opportunity to use my specific knowledge to help patients move through this tumultuous time as safely and quickly as possible.

How do you like to work with patients?

Nobody ever chooses a cancer diagnosis. It’s a hard, frustrating path and treatment can be difficult. I strive to create a space where you and your loved ones feel comfortable enough to discuss your goals for care from an infectious-disease standpoint and talk about any unease or confusion you are feeling. My approach is based on a desire to provide evidence-based, compassionate, unbiased care for every patient. I develop long-term relationships with many of the people I care for, helping them when they are at their sickest and celebrating with them when they become healthy.

Provider background

Infections in patients with cancer or weakened immune systems

I am a board-certified physician assistant who specializes in internal medicine and infectious diseases. At SCCA, I work in concert with other health care providers, such as oncologists and hematologists, to diagnose, prevent and treat infections in patients with cancer. My background includes working in primary care and HIV medicine at Group Health Cooperative. In addition to caring for patients, I am also a member of the Vaccine and Infectious Disease Division at Fred Hutchinson Cancer Research Center. In this role, I recruit patients for clinical trials and analyze data related to diseases, such as bacterial infections, fungal infections and viruses.

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 care team

At SCCA, you receive care from a team of providers with extensive experience in your disease. 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.
