Callison and RTKL Join Under New Identity

Seattle-based Callison and Baltimore, Md.–based RTKL have announced they will combine to form CallisonRTKL. The alignment of the firms has been lined up since RTKL's parent company, Amsterdam, Netherlands–based Arcadis, acquired Callison in October 2014. The union offers the firms the opportunity to leverage more geographic locations and is a response to an industry transformation that is shaping architecture and engineering firms into design consultancies, the firm’s president and CEO Lance Josal, FAIA, told ARCHITECT. Josal has been RTKL's CEO since 2009 and was appointed Callison's CEO in January.

Headquartered in Baltimore, the firm will specialize in design and planning? projects in the commercial, healthcare, and retail markets. The new firm’s leadership will include Norm Garden, FAIA, and Eric Lagerberg, AIA, who will lead the commercial practice group and the retail practice group, respectively. Karl Stumpf, AIA, will lead the firm’s workplace practice group, and Brad Barker, FAIA, will serve as head of the healthcare practice group.


RTKL recently completed the renovation of Miami's SunTrust International Center and opened Saint Agnes Hospital’s newest healthcare center in Baltimore, while Callison wrapped up a Costa Mesa, Calif., office space for Fisher & Paykel, as well as a renovation and expansion of Guildford Town Centre in Surrey, British Columbia, Canada.
