Mastery Charter School Thomas Campus, formerly the George C. Thomas Junior High School, is a secondary charter school located in the south section of Philadelphia, Pennsylvania. It is run by Mastery Charter Schools. It is located at the intersection of 9th and Johnston Streets just north of the South Philadelphia Sports Complex. Nearby are the residential neighborhoods of Marconi Plaza, Lower Moyamensing, and Packer Park; the recreational parkland of FDR Park; and the historical and new business-development center of the Philadelphia Naval Shipyard. The school is located within the boundaries of the Sports Complex Special Services District, directly on the Oregon Avenue urban corridor of small shops and restaurants anchored by larger shopping plazas on the east and west end of Oregon Avenue, and near the revitalized commercial area of Passyunk Avenue. It shares a site with the D. Newlin Fell School.

The school serves portions of South Philadelphia programmed for grades 7 through 12. It was previously part of the School District of Philadelphia. In 2009, a Charter School college-bound curriculum was established at George C. Thomas, and the interior building was renovated, along with the main entrance on the south side, facing Johnston Street.


The building was designed by Irwin T. Catharine and built in 1920–1921. It is a three-story, eight bay by three bay, brick building on a raised basement in the Colonial Revival-style. An addition was built in 1952. It features two projecting entrances with stone surrounds and a brick parapet.[2]

The school was named for George Clifford Thomas, a notable person in American history of the mid-19th century. He was a prominent banker, Protestant church and civic leader, philanthropist and collector of art, rare books and manuscripts.

He was a banking-house partner of Jay Cooke and Company in 1861, where he took a prominent part in the work accomplished by the firm, which strengthened the finances of the government so that it was enabled to carry on the Civil War. Later he partnered at the financial firm of Drexel & Co. For thirteen years, he was treasurer of the Domestic and Foreign Missionary Society of the Protestant Episcopal Church, and for twenty-one years he was deputy to General Conventions. He was elected accounting warden of the Holy Apostles and was superintendent of that Sunday School for 41 years.

In 1870, Mr. Thomas originated and organized the Sunday School Association of the Diocese of Pennsylvania, of which from the year 1875 to the day of his death in 1909, he was vice president. Among his collection of art, it included works by Whistler, Delacroix, Millet, and Troyon.[3]

The school was added to the National Register of Historic Places in 1988.[1]


SEPTA serves the school with Routes 7, 23, 47 and G. Students living at least 1.5 miles (2.4 km) away are given a free SEPTA transit pass which is issued every week in order to get to school.[4]
