How do you approach providing patient care?

Health is such a personal matter, especially when it comes to something like cancer. So it is very important to me to collaborate with patients and their families, as well as my colleagues, to form the most successful individualized plan for each patient.

Do you have any favorite memories of working with patients you’d like to share?

One very special memory I have is of a woman I took care of after a blood and marrow transplant. She was a young mom with little kids and a husband at home, and she had large photos hanging in her room of Hawaii, Greece, Costa Rica and all the other places she wanted to take her family after treatment. Her attitude brightened my days. I was a student at the time, so I moved on from that hospital right around the time she went home. I learned a few months later that she’d sent a postcard from Greece.

Whether it’s traveling or getting to watch a movie with your family from the comfort of your own home, medicine is about giving people the ability to do what they love with people they care about.

Provider Background

Area of Clinical Practice
Blood and marrow transplantation, immunotherapy

I am a certified physician assistant who sees patients at the South Lake Union Clinic and UW Medical Center – Montlake.

I would like patients to know they are the reason I chose to do this job. The relationships I form with patients and their families are so special to me. I not only care about successfully treating their cancer, but also about them living their lives to the fullest. I want patients to be able to do the things that make their lives meaningful.

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.

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.
