Proudly Serving Buffalo Residents

Rosenthal Kooshoian & Lennon LLP was originally founded shortly after World War II by Everett Barlow.  After returning from the war, Mr. Barlow opened the practice in downtown Buffalo.  Shortly thereafter, he was joined by Lester Miller and they continued as Barlow Miller until 1966 when David Siegel made partner and they became Barlow, Miller & Siegel.  One year later, Jay Rosenthal joined the firm and it was known as Barlow, Miller, Rosenthal & Siegel.  Eventually, the firm became known as Rosenthal Siegel until 1977 when Joe Muenkel became a partner and the firm changed to Rosenthal, Siegel & Muenkel, LLP.  The firm continued as Rosenthal, Siegel & Muenkel, LLP for the next 35 years until Peter Kooshoian and J. Patrick Lennon became partners and made the firm Rosenthal, Kooshoian & Lennon, LLP.
