Dell WorkmanDell Workman

Administrator, Mission Healthcare at Renton

Dell Workman was instrumental in the opening of Mission Healthcare at Renton while managing the redevelopment of Mission Healthcare at Bellevue. As a licensed healthcare administrator, Dell’s career includes acute and rehabilitative care, as well as the opening of new facilities, making him uniquely suited for his role with Mission Healthcare. As an RN, his expertise spans emergency room and intensive care units, assisted living communities, as well as skilled nursing and rehabilitative facilities.

Dell draws upon his diverse background to ensure we offer exceptional care within an exceptional environment, specifically designed to the unique needs of post-acute care patients. Whether discharged following surgery or a health event, Dell and his team will help you improve your range of motion, motor skills, balance, muscular control, and sensory perception – all with the goal of regaining your independence or as much independent mastery as possible.

As Dell often observes, “We know you’ve been through a lot. The time has come to heal and reclaim your life.” Your journey home begins here, at Mission Healthcare Renton or Bellevue.

Dell is also an avid gardener, enjoys the outdoors, and loves spending time with his wife, children, and their many grandchildren.
