A history founded
on innovation.

Graham believes it is distinct from traditional private equity firms, tracing the roots of its family industrial heritage to The Graham Group, built by engineering entrepreneur Donald C. Graham.

The Graham Group

The origins of The Graham Group date back to a design engineering firm established by Donald C. Graham in a central Pennsylvania farmhouse basement in 1960, which ultimately spawned three successful advanced manufacturing businesses. The Graham Group name has been broadened and today is used to refer to an alliance of independent operating businesses, investment firms and philanthropic entities, which all share in the common legacy of entrepreneur Donald C. Graham.

Graham Partners

Prior to the formation of its first fund in 1999, Graham Partners served as the corporate finance arm for The Graham Group businesses.


Graham Partners is a private investment firm focused on investing in technology-driven companies that are spurring innovation in advanced manufacturing, resulting in product substitutions, raw materials conversions and disruptions to traditional end markets. Based in suburban Philadelphia, the firm has access to extensive operating resources and industrial expertise and is a member of The Graham Group, an alliance of independent operating businesses, investment firms and philanthropic entities that share in the common legacy of entrepreneur Donald Graham.
