Patrick Sanders, Volunteer Youth Minister

Patrick Sanders is a Los Altos native with strong family connections to Christ Church.  His wife Kendra is a life-long parishioner who introduced him to the church, where the two were married in a beautiful ceremony back in 2001.  Their daughter Meri was born in 2004, and she attended Ventana for pre-school, while always being active with the Sunday School and Youth Group programs at Christ Church. In late 2016, Patrick experienced a calling that led him to make a transition from youth group parent to actively volunteering as the youth group minister.  Although this position was never on his radar prior to his calling, he experiences tremendous joy in facilitating meaningful youth group discussions relating to spirituality and general life topics that resonate with young teenagers. Patrick has a BS in Environmental Biology from UC Davis, and during the week he works for a company that manufactures sensors and integrated systems for advanced monitoring of environmental water resources.
