Our Firm

We’ve Built Something For You.

Gross Shuman P.C. was founded in 1959 by Gordon R. Gross and Paul Gonson. Irving M. Shuman joined the firm in 1960. For many years, the firm under the name Gross, Shuman, Brizdle & Gilfillan P.C., was led by Peter S. Gilfillan. Gordon, Irv, and Peter shared a vision of providing dedicated, client-centric legal representation at the highest level and that vision continues to guide us today.

Our wide range of individual and business clients place trust in us every day and living up to (and surpassing) their expectations is our most important job. 

Our main office is in Buffalo, New York, a place with deep history that’s becoming more vital and dynamic every day. It’s a perfect fit for us, because the city’s balance of traditional values and forward-thinking inventiveness mirrors our own approach to the law.
