FXB, Inc. is a full-service Mechanical, Electrical, and Plumbing Design and Consulting Engineering firm based outside of Philadelphia, PA with engineers licensed in thirty states. Francis Xavier Bonnes, P.E. founded FXB, Inc. in 1968 as a one-man electrical engineering firm based on the ideal that each project be carefully, innovatively, and efficiently designed. His un-matched work ethic, strong moral character, vast technical knowledge, and extensive experience allowed Frank Bonnes to become a prominent name in the electrical engineering industry throughout the world. In addition, these quality traits enabled Frank to be a strong and independent business leader. Since 1990, Peter J. Bonnes, P.E. has led the business through tremendous growth by carrying on his father’s ideals. Pete’s innate leadership, strong will, and commitment to excellence allowed the seamless addition of in-house mechanical and plumbing engineering services, along with strategic alliances with specialty consultants.
