ADG, a building design, program management, landscape and urban planning firm, announces the retirement of firm CEO, Steve Von Tungeln, AIA, IIDA.
Von Tungeln has been instrumental to the growth of the firm, which currently ranks as the second largest architectural firm in Oklahoma City, based on number of registered architects. He joined ADG in 1980 as architect and interior designer. His early work included space planning and tenant interiors for owners and brokers of most of the office buildings in Downtown Oklahoma City. Noteworthy design projects since the Chickasaw Bricktown Ballpark, Westminster School, Wagner Hall and Residential Colleges at the University of Oklahoma, Our Lady’s Cathedral, St. Eugene’s Catholic Church and several buildings on the Casady School campus.
Von Tungeln and firm president, Tom Wilson, AIA, have been partners since 1980. Scott Dedmon, AIA, LEED AP+ joined ADG in 1994 and became a partner in 2008. He will take over Von Tungeln’s CEO duties. ADG—formerly known as Architectural Design Group—officed briefly on Park Avenue before making the move to become a Bricktown pioneer in 1987, long before others had the vision that Bricktown would one day become Oklahoma City’s premiere entertainment district.
As the firm grew and added services, they consumed more and more space in the Glass and Confectionery Buildings on Sheridan Avenue, Bricktown’s main thoroughfare. Partners and employees, alike, had front seats to the constant development all around them and got to play a part in historic building renovations such as the Banjo Museum, Nonna’s Ristorante and 4 East Sheridan, home to JE Dunn Construction and Cornerstone Development. In 2002 the firm began providing program management services, first to MAPS for Kids, later to health care, municipal and school programs, and eventually to MAPS 3, which is ongoing. Current noteworthy design projects include the exterior renovation of the Oklahoma State Capitol and the First National Center.
In 2016, needing a much larger space to accommodate continued growth, ADG moved to the Fred Jones Manufacturing Building at Main Street and Classen Boulevard. The firm, which now numbers 80 employees in three offices, is once again a pioneer in a district on the cusp of exciting growth. ADG’s offices are surrounded by neighbors 21c Museum Hotel and The Jones Assembly.
ADG celebrated Von Tungeln’s retirement with a party in early February. A small list of long-time clients, consultants and contractors joined the entire ADG staff bidding him well wishes. Gifts presented to Von Tungeln during the “send-off” included a table saw and a handcrafted computer featuring walnut wood panels laser etched with all employee signatures and a laser cut firm logo as well as lifetime IT support.
ADG began in 1975 as an interior design firm. The rapidly-growing company now provides architecture, planning, interior design, engineering, program management, landscape architecture and urban planning services throughout Oklahoma and the nation, creating successful projects for government, corporate, healthcare, education, housing and religious clients. With nearly 80 employees, ADG consistently ranks as one of the largest design firms in Oklahoma. Firm projects have won design and community awards, including the Oklahoma Urban Land Institute’s Large Commercial Development award for the University of Oklahoma’s Residential Colleges, opened in fall 2017.
