Advisory Council
The Advisory Council’s purpose is to engage community members, philanthropists and educational leaders who have very limited time to volunteer but are seriously committed to the mission and values of OSS.
Many council members have been involved since our founding in 2007. We are forever grateful for their guidance, consistent dedication, and support in the form of time and treasure.
