Who Are The "PPH Advocates"?

This bright yellow sign was near the PPH meeting notice display case at Palomar Medical Center (PMC). Hard to miss. A search of the web for "PPH Advocates" resulted in the following link:

The link is to a "Palomar Pomerado Health Community Advocate Council Form." It appears that members of the community can sign up for various levels of involvement including:
"Leadership
I am interested in a leadership role within the Advocate League or Council. The Advocates League Chairperson oversees all activities of the different Community Leagues. The Advocate Council members provide oversight for the entire Advocate program."
and
"Community Events
I would like to represent Palomar Pomerado Health at local functions and events, as a Community Advocate. Periodic training will be provided so all volunteers are well versed in issues effecting the health system."

During the Prop BB campaign, these advocates helped get out the message:
"Kay Stuckhart, a volunteer and advocate for Palomar-Pomerado Health, asked that the [Escondido Union School] district staff be advocates for the passage of this proposition and that the board formally endorse Proposition BB."
