Chuck has a long-standing history in the automotive repair business.  In 1986, Chuck started his career at Angelton Garage, following by working at the Marshall-Blain Chevrolet dealership.  In 1992, Chuck, along with his good friends Allen Potter and Joe Phillips, started Ace Automotive in El Dorado, Kansas.  He continued working there until 2004 when the Lord called Chuck and his wife Jennifer and their family to Mansfield, Missouri where they would assist missionaries with automotive repair needs, international shipping needs, as well as medical supply assistance.  As more supplies became available for missionaries in their home countries, the need for this help declined.  As their services were needed less, the Harder family returned to the El Dorado, Kansas area where Chuck started Cornerstone Automotive Repair in September 2015.

Chuck desires to serve the public by providing the highest quality service possible based on honesty and integrity.
