Steve is the first President and CEO of The Overbrook Foundation. His career began at the National Institutes of Health in 1974 and has continued, since 1985, within private philanthropy. Between 1997 and joining The Overbrook Foundation in June 2002 he worked as an independent consultant, providing advice to foundations, corporations and individuals on a broad spectrum of programmatic, governance and management concerns.

Since its inception in 2005, the CMC has been active in all state-based civil marriage campaigns which have either won the freedom to marry for same sex couples or have successfully defended the freedom to marry from attack.
