Jon Marc has been ministering in Arizona churches for his entire adult life. As a young man he served under his father, Pastor Earl Ostrom, ministering in various capacities.

He graduated in 1998 from Grand Canyon University, in Phoenix, AZ, where he studied music and theater. While there, he participated in several outstanding choral groups and led the campus chapel's praise team.

After several years of full time music ministry in Payson, he came to the valley and added youth pastor to his ministry résumé. As his ministry to young people expanded, he developed a relationship with the Crisis Pregnancy Center, and taught abstinence education in valley schools via Passion and Principles for nearly three years.

Jon Marc enjoys spending time with Rosemary, his wife of 8 years, and their four boys, Ethan, Judah, Levi and Corban. He also enjoys leading people into the presence of God as well as teaching adults and youth alike the practical application of God's truth. You will find him doing both frequently at Rivers Church.
