Longtime Spokane physician Bob Hustrulid, 78, knows it's rare for a doctor's office to be inside a retirement community, but the approach makes sense to him – and he's done it before. In a long career, Hustrulid has worked at Spokane group practices and veteran hospitals. In 1999, though, he opened a solo practice and stayed until 2007 at the Waterford, now Touchmark.
