Our Leadership

Chair: Duane Rohrbacher


Duane enjoys long walks on the beach and watching the sunset, which is why he came to Orange County. In a powerhouse of two dogs and a non-profit partner, Duane leads Alumni Relations for Southern California University of Health Sciences and somehow manages his one-person consulting firm, where he serves non-profits. An expert generalist, Duane builds programs, cultivates relationships, develops curriculum, and does all sorts of fancy marketing things to round out his experiences. As a forever learner, Duane is constantly looking for new, innovative, and fun ways to help non-profits in Orange County.
