Bruce G. Alward
Principal & Executive Vice President

Bruce is the Market Leader for Wood Harbinger’s Military and Waterfront markets, as well as a co-leader of our Municipal market. His wealth of experience includes electrical engineering design as well as industrial and institutional operations management.

“I’m obsessed with the technical intricacies of design. I find great satisfaction in developing the right solutions to move clients forward and make their visions a reality. I’m deeply committed to design that works in practical terms, with high value placed on reliability, flexibility and maintenance efficiency.”

Sean M. Bollen
Associate Principal

Sean leads Wood Harbinger’s Electrical Engineering team and is the Market Leader for Wood Harbinger’s Education market. He is a skilled and detail-oriented electrical engineer with an aptitude for effective client and project management. He is also an accomplished interior and exterior lighting designer.

“What motivates me throughout the design process is making sure I thoroughly understand what the owner envisions for the project. After all, they will be using the building every week for the next 20+ years, and I want to make sure it meets their expectations.”

Thomas A. Leonidas, Jr.
Principal & President/CEO

Tom leads Wood Harbinger’s Information and Communication Technology (ICT) and Security team. He is an accomplished electrical engineer and technology consultant with keen business acumen. Tom’s varied experience allows him to adapt to future changes in technology and his designs provide long-lasting, valuable benefits for the owner.

“We succeed when we clearly and deeply understand our client’s business, far beyond the technical issues we are here to solve. It sounds simple, yes, and often a step skipped. I’ve found that by going slow up front to align ourselves with the bigger picture, we can gain momentum to the finish line and do so with the certainty that we’re running in the right lane. By working collaboratively within the context of a common vision, we focus all of our expertise toward a singular purpose. That’s our promise as trusted advisors to our clients.”

Jeffrey L. Yirak

Jeff leads Wood Harbinger’s Mechanical Engineering/Industrial Systems and Commissioning teams. He is also a co-leader for Wood Harbinger’s Municipal market. His commissioning philosophy promotes a holistic and sustainable approach to building operation, ensuring that interconnected systems function in harmony with each other for maximum energy efficiency and energy conservation.

“Robert Burns recognized that ‘The best laid schemes of Mice and Men / Oft go awry, / And leave us nothing but grief and pain, / For promised joy!’ — This is the problem that commissioning was born to solve. We are a group of people for whom “good enough” is not enough, and we work to make systems work correctly, free from grief and pain.”


Senior Associates

Bruce J. Higgs
Senior Technical Associate

Bruce has earned a solid reputation of proficiency in all technical aspects of building mechanical systems.  His design abilities are enhanced by his skill in troubleshooting existing systems and correcting operational difficulties.

“I’m way into the details–the project, the program, the potential efficiencies, how all of the building systems relate to each other. I get into the nitty gritty because I care about the facilities personnel who will inherit our designs and will do anything in my power to make sure they receive a system that actually works as intended. Becoming a trusted and appreciated client ally, who serves as a core member of their team, is something I take very seriously.”

Ralph E. Maier
Senior Technical Associate

Ralph leads Wood Harbinger’s Specifications team and oversees the firm’s Quality Control program. He has diverse market sector experience, a proven ability to meet multiple deadlines, and works well under pressure with engineers, management, and clients.

June S. Mechure
Senior Associate

June is a co-Market Leader for Wood Harbinger’s Healthcare market. He is an innovative electrical engineer and strong project manager with a breadth and depth of experience in healthcare facility engineering.

“For the past 19 years, 98% of my projects have been healthcare projects. What keeps me going is the knowledge that every project I’ve worked on, at the end of the day, has an impact on changing and saving peoples’ lives. You’ll never know what is going to end up on that design table, but it will always affect someone’s family and loved ones. My goal is to make sure that Wood Harbinger provides sound design solutions and creates solutions that enrich people’s lives.

I also enjoy working on healthcare projects because of the fast track nature of technology. I stay up to date on the latest and greatest in healthcare technology to connect engineering to life in unexpected, and forward thinking new ways.”
