Christopher Catton

Christopher Catton, MD
Associate Medical Director

Medical School: University of Washington 1989

Residency: Internal Medicine Spokane 1992

Board Certification: American Board of Internal Medicine

Growing up as the son of an Air Force jet pilot allowed me to live in 12 different cities in my first 11 years of life. When my dad retired in 1974 we moved to Spokane, Washington, and I established roots in the Pacific Northwest. I met my wife Geri while in medical school and after residency we moved to Yakima where we are raising our five children and one golden retriever. I enjoy coaching my sons' baseball and basketball teams as well as attending my daughters' dance recitals. For our first 11 years in Yakima I enjoyed a "traditional" internal medicine practice. Five years ago, I transitioned to hospital medicine as one of the founding physicians of our growing hospitalist team. The small town feel and family friendly culture coupled with its close proximity to Seattle makes Yakima a great place to live, raise a family and practice medicine.

I was born and raised as a Filipino-Chinese, and eventually left the Philippines Islands after completing my B.S. in Medical Technology and MD as a Dean's Scholar at the University of Santo Tomas in Manila, graduating Cum Laude & Magna Cum Laude respectively. I moved to the United States in 2003 and settled in the less humid and hurricane-prone sunny island of Galveston, one hour south of Houston, Texas, where I completed my internship and residency at UTMB. I was honored as the "Most Likely Smiling Intern & Resident Award" two years in a row. My passion for hospital medicine led me to move to the fseasoned weather of the beautiful Pacific Northwest in the apple basin agricultural community of Yakima where I have been a hospitalist at YVMH since 2007. I have been very active in the medical community and hospital committees, including the Pharmacy & Therapeutics Committee, Anticoagulation Committee and Lab Q+ Committee, and serve on the YVMH Medical Executive Committee. I was appointed to the position of Chairman of the Department of Internal Medicine at YVMH in 2009 and also appointed to the faculty of Pacific Northwest University of Health Sciences as an Assistant Professor in the Department of Clinical Medicine. In 2011, I was elected Fellow of the American College of Physicians. In my spare time, I like to travel and attend continuing medical education workshops.

Physician Recruitment:

We have reduced the number of Physician and Provider positions we are recruiting for in the wake of the COVID-19 pandemic. Should you be interested in possible employment with Virginia Mason Memorial, please contact us at physicianrecruitment@yvmh.org. We are actively reviewing our staffing needs and new positions are being approved for posting. We appreciate your interest in us and hope to have the opportunity to consider you for a role with VMM.

Additional Spiritual Resources During COVID-19

Chaplains at Virginia Mason Memorial Hospital provide care for every patient regardless of their personal beliefs or non-beliefs. For support, assistance, prayers, and all other spiritual care requests, please email spiritualcare@yvmh.org or call the spiritual care office: (509) 575-8035


There are times when a direct face to face spiritual care conversation is not the best option (due to distance, a pandemic, patient preference). That's where Tele-Chaplaincy provides another possibility. You can request chaplain support using your personal, or hospital room, phone. Calls are confidential. Chaplains will listen, provide encouragement, offer help and resources, and if desired, offer prayer. If you are part of a faith community a chaplain can help you connect with them.

Virtual Chaplaincy

Without regular visits from family and friends a stay in the hospital can be even more challenging. One of our newest offerings, Virtual Chaplaincy using Zoom, helps make connections. By contacting the Spiritual Care team at the email or phone number above you can request a Zoom meeting. Family and friends throughout the Yakima Valley, from the four corners of the state, from across the country and even internationally, are meeting with patients via Zoom to offer their love and support. Due to the popularity of this option scheduling and frequency may, at times, be limited.

Hospital Lab Services

All out-patient lab services - including newborn screens and bilirubin collections - will now be provided at Memorial Cornerstone Medicine, 4003 Creekside Loop. Hours are 7 a.m. to 6 p.m. Monday through Friday; 8 a.m. to noon, Saturday and Sunday.
