GG&C Bus Company originated in 1967 when three local area businessmen, Mr. Bill Good, Mr. Wendell Gower, and Mr. William Clark purchased Rex Allison Bus Company, at which time the Trinity Area School District was formed.
Soon after, they purchased John Warren Bus Co. that served Amwell Township, and Lester Morrison Bus Company who served North Franklin. These, along with the Washington School District are the school contracts they operated until they sold to Mr. John Lenzner in April 2004.
Mr. Lenzner grew the business by securing transportation contracts with Avella Area School District in 2005, McGuffey Area School District and the University of California in 2010, and The Linsly School in 2011. In 2015, John sold the company to Landmark Student Transportation, Inc.
