He is survived by his wife of 21 years, Mary Ann; his daughter Machteld Van Lennep of South Africa; his three sons Evert-Jan of Federal Way, Anthony Joseph of Portland, Ore., and Paul Andrew of Federal Way; and two granddaughters Pia and Tessa.
Tony, as he was known to his friends, and Toon, to his family, studied medicine in Amsterdam and Leiden, coming to America in 1958 to complete his residency and internship at Sacred Heart Hospital in Spokane.
He began his career in a traditional practice of internal medicine in Spokane, then moved to Quincy in Eastern Washington in 1962 to be a small-town family doc in general practice. Through the 1970s, he continued his medical career in Bellevue and Bainbridge Island.
In the early 1980s, he became interested in chiropractic and naturopathic medicine and began incorporating alternative medical practices, becoming one of the areas earliest alternative medical M.D.s in Federal Way.
He continued his holistic practice — which one could almost call pastoral medicine — until 1999 when he moved to Whidbey Island. He had a rare and intuitive sense to counsel his patients to remember that to heal the body, they may need to heal the soul.
He closed his office on his 80th birthday. He nourished his soul during his last 10 years as his own health was declining by gardening and hiking with his mobility scooter along with his wife and dog, Tiger, on trails and back roads all over Whidbey Island. He has taken his last journey to the place where all his questions will finally be answered.
A memorial service will be held at 2 p.m. on Saturday, Feb. 18 at the Unitarian Universalist Congregation, 20103 State Highway 525, Freeland, WA 98249.
