Senior Advisory Board
Comprised of 12 South Bay residents who are Torrance Memorial IPA members, the Torrance Memorial IPA Senior Advisory Board Committee was created in 2009 with the goal to improve the care and services offered to members. The board meets quarterly with Torrance Memorial IPA’s executive team to share medical care concerns, pose questions and offer input for improvement and new services. The board’s ideas have developed into valued programs like the Torrance Memorial IPA newsletter that helps members learn about the variety of services and resources available to help manage their health care.
