Engineering Expertise, Strategic Vision

As Principal and Director of Building Performance & Sustainability, Joe Hofstetter connects innovation with strategy to strengthen client relationships across markets.

“What’s always been great about building performance and sustainability is that it reaches across all of our markets,” Joe says. “It’s given me a diverse understanding of what our clients need and created opportunities to bring new ideas to project teams.”

Joe sees thermal electrification and building commissioning as key trends shaping the next five years. “Thermal electrification isn’t one-size-fits-all. Our energy grids differ across regions, so we work closely with each client to find the right solution. Commissioning is also growing, with more clients relying on us to guide them through new code requirements and the benefits these services bring.”

For Joe, building strong client relationships isn’t just about technical solutions; it’s about connecting the right expertise to the right opportunities. “Our best asset is our people and the services they provide. Leadership is about championing that and shaping a brand that reflects it,” he says. This reflects his belief that leadership is as much about fostering talent and collaboration internally as it is about delivering results externally.

“Growth comes from understanding your strengths and how they fit into the bigger picture,” Joe says. “When you focus on applying your skills to make a positive impact, the rest tends to fall into place, whether you’re developing as a technical expert, a leader, or both.”

Empowering the Next Generation of Engineers

Every project presents new challenges, and to Principal Matt Priebe, that means new opportunities to learn and collaborate. “It lets you know there is always something new to learn and always room to grow,” he said. Matt focuses on collaboration and growth when mentoring and leading his team.

That collaborative spirit extends into how Matt leads and develops younger engineers. “We empower younger engineers to take initiative and build confidence, that’s how growth happens,” he shared. He supports younger engineers as they take on new responsibilities, explore ideas, and grow their skills, providing guidance every step of the way.

At the same time, Matt believes it’s essential to remain a strong technical expert. “It requires deliberate prioritization and delegation while maintaining a strong technical foundation,” he explained. That balance gives clients confidence while setting an example for the next generation.

Looking to the future, Matt is energized by emerging technologies like AI and microgrids. He sees the potential for AI to increase efficiency and quality, and for microgrids to strengthen energy resiliency and help manage rising utility costs.

For engineers who aspire to leadership, Matt’s advice is clear, step up. “There is no substitute for experience,” he emphasized. Volunteering for new challenges not only shows initiative but also demonstrates that you’re already leading.

Where Relationships Guide Design

To Ray Hoon, engineering is about more than systems and structures. It’s about the people involved and the relationships built along the way. Since joining Karpinski Engineering in 2006, Ray has built his career by staying closely connected to his clients and projects, making sure every detail reflects their goals and vision.

Ray’s path started with a B.S. in Mechanical Engineering from Cleveland State University, earned while working full-time in the field. Over the years, he has applied his technical skills across a wide range of market sectors, including corporate, higher education, government, and civic work. His portfolio includes the Benesch Key Center renovation, Cleveland Foundation Headquarters, Midtown Collaboration Center, numerous projects at Kenyon College, and historic preservation work. He has also worked on facilities for the U.S. Coast Guard and U.S. Customs and Border Protection, and delivered projects for clients such as KeyBank, FirstEnergy, Goodyear, Swagelok, Westfield Insurance, and Dealer Tire—spanning both new construction and adaptive reuse.

Known for his hands-on leadership style, Ray guides teams through complex challenges with a balance of technical insight and a genuine commitment to client care. His experience with sustainable systems — including geothermal, underfloor air distribution, and water source heat pumps — complements his focus on creating spaces that support people and purpose.

“I am grateful to work closely with our engineers to find creative solutions to complex problems.“

Beyond the engineering, Ray’s focus remains clear: building long-term partnerships based on transparency, responsiveness, and mutual respect.

A Legacy of Leadership: Jeremy Bowers’ Path to President

Jeremy Bowers’ journey at Karpinski Engineering spans more than two decades and reflects a steady commitment to growth, leadership, and values-driven work. Since joining the firm in 2000, he’s taken on roles that have shaped both his career and the company’s future. In 2006, he launched the Akron-Canton office—an initiative that quickly grew into a vital part of the firm’s operations. “That office started with a few people and a lot of belief in what we could build,” Jeremy recalls. “Today, it’s a testament to what’s possible when we lead with purpose and stay connected to our clients.”

Throughout his career, Jeremy has emphasized the importance of developing people. He believes leadership is most effective when it’s shared. “The best ideas don’t always come from the top,” he says. “I’ve seen how powerful it can be when we empower others to lead.” That philosophy helped develop Karpinski’s formal leadership training program, which has supported more than 50 emerging leaders over the past decade. His influence has helped strengthen the firm’s internal culture, giving rise to new principals and team leaders across departments and regions. It’s an approach rooted in collaboration, trust, and a deep respect for the expertise of those around him.

Stepping into the role of President, Jeremy remains focused on guiding the firm forward while honoring the values that have long defined it. He’s particularly interested in how innovation - especially in technologies like BIM and AI - can support smarter project delivery and better outcomes for clients. “We have an opportunity to evolve with the industry while staying grounded in what’s made us strong,” he says. “Our future is built on the same foundation that’s always guided us: integrity, service, and a commitment to excellence.” With that mindset, Jeremy is poised to lead Karpinski Engineering into its next chapter - one created by shared leadership, strategic growth, and a continued dedication to the people they serve.

Guiding Strategy, Inspiring Success

Frank Eisenhower’s journey at Karpinski Engineering began with hands-on work in the field and has evolved into a leadership role where he now serves as Principal, Chief Financial Officer, and Director of Columbus Operations. In 2007, Frank played a key role in establishing Karpinski Engineering’s Columbus office. His work with significant projects, including those at The Ohio State University, and frequent travel between Cleveland and Columbus helped lay the foundation for the thriving operation that exists today.

Frank’s role spans all aspects of managing the Columbus office and overseeing corporate financial strategy. “My role is everything and anything it takes to ensure the success of our operations,” he explains. “I take great pride in leading by example—whether that means tackling a complex corporate decision, assisting with fieldwork, or solving a challenging engineering problem.” With over 30 years of experience, Frank remains passionate about solving complex challenges, particularly through projects like the Severance Hall addition and the Cleveland Museum of Art renovation, which have a lasting impact on the community.

Looking ahead, Frank envisions continued growth for the Columbus office, with plans to expand the team to 40+ employees and further strengthen relationships with architects and local businesses. He also focuses on broadening the firm’s service offerings and advancing programs like the R Engineering Team (RET) mentorship initiative. Reflecting on his career, Frank recalls advice from Jim Karpinski on his first day: “Taking care of our clients’ needs. Never losing that focus.” This philosophy remains at the heart of Frank’s leadership and Karpinski Engineering’s commitment to delivering high-quality solutions.
