Growing up with a high school shop teacher as a dad, there was no way Bill Leuci could escape an early introduction to tinkering. Mechanically-oriented from a very young age, Bill spent his childhood and high school years taking things apart, putting them back together, and then figuring out what he could make with the leftover parts. This was particularly helpful when his Chevy ended up in dad’s high school auto shop. 

​

At the same time, a good friend’s dad was an MBTA electrical engineer turned mad scientist. Set up in their garage, the boys set about doing what creative kids do: building things with whatever they could get their hands on. Encouraged by their children’s interest, both dads supervised many electrical engineering experiments over the years, including the construction of a mini Tesla coil and a Van Der Graff generator. 

​

This interest in the mechanical and robotic world led Bill to Tufts University, where he expected to enter the biomedical field. But, a summer job at Metcalf and Eddy changed his mind. While engineering classes in school focused on small circuitry and computer engineering, his summer job was filled with large power system engineering for a large water and wastewater firm. With a renewed interest in all things electrical and a belief in the field's potential for long-term viability and satisfaction, Bill spent his senior year studying the field of power engineering. After graduation, he was hired by M&E.

​

Before anyone described "mission critical" as it is known today, Bill spent the early part of his career engineering the critical power systems for military installments around the world, including work on radar systems, communications systems, and data centers for the U.S. Navy, Air Force and NATO, among other branches of the armed services. 

​

While working at Vanderweil Engineers, Bill was introduced to building systems engineering, where he completed the FBI Forensic Laboratory in Quantico, Virginia, and the IRS Martinsburg West Virginia facility marking the start of electronic tax filing. He further expanded his mission critical repertoire when he opened D&L Engineering in 2002 to focus on mission critical and laboratory facilities nationwide, before he sold it to X-nth, now EXP Global, in 2006. Bill helped X-nth expand from 3 East Coast offices to 8 national offices and headed up the mission critical practice nationally and the laboratory practice in the Northeast. This experience enabled him to take on the role of group leader at RDK, where he helped grow the Boston office from 2011 through 2014. 

​

Restless with the standard business rhetoric of most engineering firms, Bill had ambitions of building a better company. Brian Mulkerrin and Bill discussed their ideas, and Brian had a different take on the standard MEP approach: they would start a company that was focused on electrical systems only, and it would be principal-driven and principal-executed. In this niche arrangement, clients work with the engineer who envisioned the work. With complicated systems engineering experience in spades, clients benefit from highly technical and experienced engineers focused on their projects throughout the entire lifecycle. 

​

Brought up in a large Italian family, brotherhood is paramount and Bill considers Brian and Ryan to be his brethren. When he’s not working, Bill focuses on his children, daughters Jaqueline and Sophia, who join their dad on fishing and skiing expeditions, or spend time watching him play one of numerous sports several times a week.
