SiGenix was founded by engineers who had honed their collective trades in multi-national medical, transportation and defense corporations. After having grown weary of attending countless meetings that had little to nothing to do with designing and engineering, the original founders decided to form SiGenix where Engineering state of the art systems for would be Job One.
Even though some names have changed throughout our 14 year existence, the drive to engineer hardware and software solutions is not only our job, but our passion.

Welcome Back Rich!
After several years away from SiGenix, our founder and former CEO is back and a very welcomed addition to our team. Rich was brought out of retirement to support new and existing business opportunities in a very busy engineering services marketplace. Rich holds a B.S.E.E. from Florida Atlantic University and an M.S.E.E from Rensselaer Polytechnic Institute. After college, Rich worked for General Dynamics, Bombardier Transportation and Respironics, where he developed power supplies and control boards for the defense, transit and medical industries.
Rich left industry in 2000 to start SiGenix, Inc, which specialized in product development for a variety of industries. The firm was honored by the Pittsburgh Technology Council with the Rising Star Award in 2007. As CEO, Mr. Riggio grew revenues every year ($200,000 to $2.1 million) as well as the firm’s client base (3 to 25). At the time of his departure from full-time duties, the firm grew from just himself to six engineers and 2 support staff.
