"I believe in a loving God whom we know through the teachings of Jesus and who wants the best for each and every one of his children," he said.
His role with the Marcellus First Presbyterian Church is to help others develop their relationship with God, but also to work together as a team, one which includes the entire community.
As an ecumenical community, the Presbyterian, Methodist, Lutheran, Baptist and Catholic churches unite and work together on many occasions. According to Grossman, the Presbyterian church has a "strong bent" toward helping others whether it's raising funds or simply inviting others to a service regardless of their background.
"There's a strong ecumenical tradition," Grossman said. "It's less about (having) to be Presbyterian that it is how can we help you to be the best that you can be."
In helping him be the best that he can be, Grossman's family has been very supportive of his role in the intentional interim ministry, which has caused a few moves for Grossman and his wife of 26 years, Allene. Together the couple has five grown children, eight grandchildren and two great-grandchildren.
Grossman has advice for others, not just those in his congregation, which includes those searching for a church to join and those who maybe are just looking for a change.
"I think you want a church where the message rings true with you," he said.
Services are held at 10 a.m. Sundays at the church located at Main and North streets in Marcellus.
