In 1991, professional engineers Al Casey, Joe Straub, Ron Mead and Bill Liberto form M/E Engineering, P.C. Rather than providing multiple services, the partners decide to concentrate on what they do best - mechanical and electrical engineering - to maximize value for their clients in Rochester, New York. The business quickly grows in Rochester and throughout New York State.

In 1996, M/E expands to Buffalo, New York with partner Bill Liberto overseeing the new office. The office grows to fifteen employees and in 1999, the staff increases to more than 50 when M/E acquires the assets of Buffalo-based engineering firm Wilson, Klaes, Brucker and Worden, P.C. The Buffalo office is now located at 60 Lakefront Boulevard, in downtown Buffalo.

In 2002 M/E moves the Rochester office to 150 North Chestnut Street in Rochester’s Cultural District.

Al Casey, president of M/E Engineering, oversees company operations from the Rochester office and Ron Mead manages the Rochester operations.

M/E’s Capital District office opens in 2003 in Albany, New York. Joe Straub is the partner in charge of the Capital District office which is located at 10 Airline Drive in Albany.

M/E’s Syracuse office is added in 2004 at 441 South Salina Street in downtown Syracuse. Joe Straub also heads the Syracuse operation.
