Past Chairman of the Board and CEO John Wiesner was born in Richmond, Texas and grew up in Hempstead. He married Beth Sorsby, also of Hempstead. They were graduates of Southern Methodist University. Mr. Wiesner started his automotive career in Hempstead in 1949, then moved to Baytown. In 1977, he purchased the Buick-Pontiac-GMC dealership in Conroe which is now the main headquarters for the Wiesner Automotive Group. Today the Wiesner Family carries on the tradition started by their father and grand-father by maintaining that great level of trust through community involvement, promoting quality brands and standing behind the motto Buy for Less at Wiesner.
