Jason was born and raised in West Michigan and attended South Christian High School. After graduating from high school he attended Trinity Christian College in Palos Heights, Illinois, a southern suburb of Chicago. Armed with a history degree he decided to apply to law school and chose to stay in Chicago to obtain his law degree. After graduating from law school and passing the bar he took his first job with the Ogemaw County Prosecutor's Office.

After a year in the Ogemaw County Prosecutor's office Jason took a job in private practice working as an associate at Hettinger & Hettinger PC focusing primarily on criminal defense and family law. While working at Hettinger & Hettinger was a valuable experience a position as an associate at Hess, Hess, & Kmetz became available allowing Jason to take a position as an attorney in the Grand Rapids area this position also allowed him to gain valuable experience in the area of family law, specifically representing men in divorce and custody matters.

Working as a prosecutor, criminal defense attorney, and an advocate for men going through divorce and custody matters has given Jason a unique perspective on both criminal and family law matters. It's this perspective that has helped him advocate for clients in both criminal and family law cases all over Michigan.

In his free time Jason enjoys spending time outdoors with his family camping and boating. Jason also enjoys golfing and skiing in his free time. Jason along with his wife and sons also attend the Cascade campus of Ada Bible Church.
