Christian and Jennifer moved into Berks County in the fall of 1988 and have three adult children: Matthew Leinbach (son) & Amber Day, Laura Leinbach (Daughter), and William (son) & Hannah Leinbach. Laura has three children; Gracie, Logan & Darbie. Christian and Jennifer reside in a log home built by hand with family and friends near Hamburg.

Christian Leinbach was elected in 2007 to serve his first four-year term on the Berks County Board of Commissioners. Upon reelection in 2011, he was selected by his peers to serve as Chairman of the Board. He was reelected in 2015 and again in 2019 and was once again selected to serve as Board Chair. Christian is a member of the Election Board, the Prison Board and the Retirement Board. He chairs the Salary Board. Additionally, Leinbach is a director on the Berks County Conservation Board and the Berks Community Television Board.

Nurtured by first-generation Slovak grandparents (his mother's parents) and his Pennsylvania Dutch grandparents, Clem and Anna Leinbach, young Christian learned firsthand the value of hard work, frugality, and the blessings of living in America. In 1979, He accompanied his Aunt Mary and Aunt Alice to visit relatives who lived behind the Iron Curtain in what was then Czechoslovakia and Hungary. It was an eye-opening, life-changing experience that became the impetus for his involvement in government to preserve freedom for future generations.
