The Face Behind Pittsburgh’s Modernism

Tasso Katselas was prolific in his home city for the second half of the 20th century, but his work remains underappreciated.

Anyone who has spent time in Pittsburgh has likely come across at least a few of the buildings designed by architect Tasso Katselas, but you’d be forgiven for not recognizing his name.

Katselas, now 91, transferred ownership of his firm in 2005 (now called TKA Architects, Inc.) but remains a consultant at the practice and a trenchant observer of the built environment. His body of work remains a forgotten yet ubiquitous aspect of Pittsburgh’s landscape.
