New York Office Opens

New York Office Opens

In late 1972, George Hellmuth receives agreement from Gyo Obata and George Kassabaum to seek a merger opportunity for the establishment of an HOK presence in New York City.

Hellmuth’s search leads to Kahn & Jacobs, P.C., a 100-year-old architectural practice that designed several high-rise office buildings for prominent real estate developers. A merger proposal is soon developed and, by early 1973, the New York office is established.
