Dr. Jill Casey is a board-certified Family Medicine physician and International Board Certified Lactation Consultant based in Edmonds, WA, and a founding provider at Trillium Concierge Medicine. As a Ms.Medicine Affiliate, she brings more than a decade of clinical experience across all ages, all genders, and the full arc of a family's health — with specialized expertise in breastfeeding medicine and women's health.

Dr. Casey's path to family medicine started early. As a student-athlete, she spent time in the athletic training room learning anatomy and injury rehabilitation alongside her peers — and realized she wanted to do this for life. Medical school confirmed it: she fell in love with every rotation, and chose family medicine because of the variety of patients, ages, and medical conditions. After more than ten years practicing family medicine with obstetrics, she pursued IBCLC certification to continue supporting mothers and babies through the often-overlooked challenges of breastfeeding. She's now adding menopause care to her focus — because the gaps in women's healthcare don't stop at postpartum.

Patients describe Dr. Casey as thoughtful, nonjudgmental, and genuinely present. She listens before she leads. Her approach to treatment planning is collaborative — she works with patients as a partner in forming the best treatment plan — and her own personal health journey has deepened her understanding of how hard real change can be, and how much it matters to have someone in your corner who believes you can get there.

"Caring for someone's health is an honor. I approach healthcare as a partnership where I help guide and encourage people to be their best, most healthy selves."

Outside of medicine, Dr. Casey coaches volleyball, snowboards, and spends time in the garden growing berries, vegetables, and flowers for cutting. Her two daughters keep the family busy with soccer, volleyball, and dance — and she wouldn't have it any other way. The same energy she brings to staying active herself shows up in nearly every patient visit.

Through her work with Ms.Medicine, Dr. Casey joins a national network of clinicians dedicated to advancing women's healthcare through evidence-based, relationship-driven, and time-rich medical care.
