  • sam eichel

    worship director

    Sam was born and raised in Grand Island, New York and grew up attending Cornerstone Church. He graduated from Houghton University with a Bachelor’s Degree in Instrumental Music Education.

Over the next few months, he saw the Lord provide and put things in place which ultimately led to this position.

    Sam feels extremely blessed to be able to serve on staff at his home church where his family attends. “The events that led me here are a testament to the faithfulness of believers who have gone before me and the leaders who have poured into me.”
