Neff Power, Inc. was founded in 1965 by John and Loretto Murphy. Partners Patrick DeStefano and Harry A. Heitmeier joined the firm in 1972 and 1975, respectively. The current principals of Neff Power, Inc., Neff Press, Inc., and Lee Engineering, Inc. are John and Loretto Murphy and Harry A. Heitmeier.

Neff Power began as an industrial distributor of fluid power components and controls. Over the years, Neff Power added to its product mix and today is a full-service automation solutions provider, handling electrical control, motion control and fluid power. The technology acquired from these activities resulted in the development of several proprietary products. A series of high speed, hydraulic "C-frame" production presses was introduced in the late 1960's. This resulted in Neff Press being incorporated in 1990. Similarly, a hydraulic rotary valve actuator was developed in 1979. This led to Lee Engineering being incorporated in 1989.

Today, the Neff Group employs over 50 people. It has evolved into a unique organization with an exceptional mixture of sales, engineering services, manufacturing and fabrication capabilities.
