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

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’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.”

Bruce A. Pitts

Bruce has exceptional breadth of expertise in all types of mechanical and industrial systems, controls, commissioning, systems evaluation, and trouble-shooting.

“While working in the design and construction of military, higher education and hospital buildings throughout the 1970s & 1980s, I could see how delivery of these buildings was getting worse, not better. The greater the complexity, the harder it was to deliver a functional building. I knew there had to be a better way. So, for the last 20 years, I’ve dedicated my career to commissioning, as a means of bridging the gap between design intent and final delivery. Fulfilling the dream of buildings that work like a charm in a cost-effective manner is where I find the greatest satisfaction.”

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.”

Joseph A. Leysath

“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.
