Eventide Team


William F. House, MD, MS

I’m a family physician passionate about delivering great care. I’m a graduate of Tulane University School of Medicine and did my training in NY at the Institute for Family Health. I’ve worked in the healthcare field for over a decade. Before that I worked in software engineering. I hold a Masters in Pharmacology also from Tulane and earned my undergrad at the University of Colorado, Boulder in Psychology/Neuroscience. I’m board certified in Family Medicine and believe strongly in educating my patients. My main focus is to develop a healthcare plan with you rather than for you. I enjoy spending time on our amazing island with my wife, Sherrie, our two daughters, Jackie and Savannah and our dog, Hooper.

Heather Christensen, PA-C

I am a certified physician assistant and enjoy working with patients of all ages. I graduated with Master’s degree in Physician Assistant studies from Idaho State University. Before seeking the higher degree I enjoyed working in clinical laboratories after obtaining undergraduate degree from Utah State University. I worked in a women’s health clinic before moving to Friday Harbor with my family more than 5 years ago. When not at work I spend time with my husband, 2 kids and 2 dogs. I am grateful to be in a place where people care for and support one another.
