After almost two years of hoping, reorganizing our resources, researching, and waiting, Grace Presbyterian Church is delighted to introduce the new senior pastor, the Rev.

Mark officially began his role as pastor on Wednesday, April 15. 

Mark, a native East Coaster obtained his undergraduate degree from Hamilton College in New York and a Masters of International Business degree from the University of South Carolina in Columbia. He and his wife Pat moved to California where he worked in finance in the Silicon Valley. During that time Mark and Pat attended Trinity Presbyterian Church in Santa Cruz, CA. With the support of the church, Mark explored the call to ordained ministry.  He attended and graduated from Union Presbyterian Seminary in Richmond, VA.  His extensive career has led him to serve in Associate and Senior Pastor roles in both small and large churches in Florida, Alabama, North Carolina, California, New Jersey and now back to California.
