Founded in 1993, the firm has an interesting history which provides some insight into the close working relationship formed by the founding partners, who have been working together for virtually their entire careers.
The founders, Don McMahon and Mike Mann, were friends and colleagues in graduate school in the 1970s. After graduation their career paths diverged, but they both knew they wanted to specialize in underground and environmental engineering. Both eventually returned to Buffalo as engineers with a large firm, then decided they preferred to form their own partnership.
The third partner, Ken Fishman has a doctorate in civil engineering in addition to his P.E. license, and moved to Buffalo in 1987 as a faculty member of the School of Engineering & Applied Science at the State University at Buffalo. The partners became familiar with his work, which included assessing seismic vulnerability of bridge abutments and building foundations, and began collaborating with him on certain geotechnical projects. Ken joined the firm in 1994, adding research experience and vast technical knowledge and theoretical expertise.
