Eventide Team


Will House, MD

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, Jackie’s husband, Collin, our grandson, Nathan and our dog, Hooper.

Fulfilling a dream I had as a nurse for over two decades, I am now a board-certified Family Nurse Practitioner on San Juan Island. I obtained my FNP certification after graduating from the University of Cincinnati post-master’s program. My BSN is from Azusa Pacific University and I hold a master’s degree in nursing education from Grand Canyon University. For a number of years, I was part of a pediatric specialty team who flew our tiny patients for emergency care and, when not at Eventide Health, I still fly patients on Island Air Ambulance. Since coming to Eventide, my focus is on women’s health. It’s an amazing experience to build a health care plan with someone and see it come to fruition. In my free time, I enjoy hiking our beautiful islands, solving puzzles of all kinds, reading, and spoiling my cat, Henri.

First and foremost, I am a wife (30+ years) and mother. Family is the most important thing in my life; we love having our children and grandchild here on the island. We enjoy nature & hiking, cooking, finding fun games to play, great conversation, and spoiling our dog, Hooper. Professionally, after obtaining a BS degree in mathematics and a MA degree in Education, I worked as a MS/HS mathematics teacher for 25 years. Moving to the island is a dream come true for our family. I feel truly blessed to support our staff and serve our community as the office manager of Eventide Health.

After growing up all over the country, I moved to the island in early 2020 with my family after my dad took over what would become Eventide Health. Before coming to the clinic, I worked at both Roche Harbor and the local elementary school. These jobs have allowed me the opportunity to get to know the island. I now work at Eventide as a member guide and in reception. I’ve always enjoyed helping people and am excited to have the clinic as a catalyst to serve the community that has brought so many wonderful things into my life; the best of which is my husband and our baby boy.

I'm a registered nurse with a Bachelor of Science in Nursing from Trinity Western University and a Diploma of Tropical Nursing from the London School of Hygiene and Tropical Medicine. I grew up on the island and have spent most of my 13 year career in nursing thus far here. I'm passionate about collaborating with patients to provide good health care that helps meet their goals for their health. I love this island and this community, and I love that I can give back by working as a nurse here. In my free time I enjoy cooking, reading, running, playing soccer, hanging out with my nieces and nephews, and hiking with my husband, Nic.
