American Elevator, one of the Midwest’s leading independent elevator service providers, today announced a strategic partnership with Elevator Service, Inc. (ESI), designed to support the company’s continued growth while preserving the customer-focused approach, technical expertise, and operational excellence that have defined the American Elevator brand for nearly two decades. Maven Group served as advisors to American Elevator.
Founded in 2008, American Elevator has earned a strong reputation by providing comprehensive elevator maintenance, repair, modernization, and new installation services. The company has become a recognized market leader in elevator modernization, helping customers extend the life of their equipment through innovative, non-proprietary, and cost effective solutions backed by exceptional technical expertise. Under the leadership of Darrin Middendorf, American Elevator has continued to strengthen its reputation as one of the Midwest’s premier independent elevator companies. By combining deep technical knowledge with a customer-first mindset to serve as a trusted partner for building owners seeking responsive service, modernization expertise, and long-term reliability.
“Since day one, our mission has been to provide customers with exceptional service, honest guidance, and the technical knowledge they need to make the best decisions for their buildings,” said Darrin Middendorf. “Partnering with ESI allows us to build on that foundation by investing in our people, expanding our capabilities, and positioning American Elevator for continued growth while preserving the independence, responsiveness, and customer focused culture our customers have come to expect.”
As part of the partnership, American Elevator will join forces with ESI Indiana, another reputable brand led by Jason Aldridge. ESI will combine these two highly respected independent organizations under the American Elevator brand. Together, the organizations bring complementary strengths, expanded resources, and decades of industry experience to better serve customers throughout Indiana and the surrounding region. Darrin Middendorf and Jason Aldridge will both continue to serve in key leadership roles as the combined organization enters its next phase of growth.
“What excites me most about this partnership is how well these two organizations complement one another,” said Jason Aldridge. “American Elevator’s outstanding technical expertise, modernization capabilities, and reputation for service, paired with the momentum ESI Indiana has built across the state, creates an organization that’s exceptionally well positioned to serve customers throughout Indiana and continue growing across the region.”
Jason Vallee, CEO of ESI, echoed these comments, adding that the partnership reflects the organization’s commitment to investing in exceptional independent elevator companies and creating stronger regional platforms built on shared values and complementary strengths.
“At ESI, we seek partnerships with exceptional companies that have earned the trust of their customers through strong leadership, technical expertise, and an unwavering commitment to service,” said Vallee. “American Elevator represents exactly that. They have established themselves as one of the Midwest’s premier independent elevator companies and a recognized leader in elevator modernization. At the same time, ESI Indiana has built tremendous momentum, expanding from Northern Indiana into the Indianapolis market while developing strong customer relationships across the state. Bringing these organizations together creates an even stronger regional platform that will continue investing in our people, our customers, and the communities we serve for years to come.”
The partnership reflects a shared commitment between American Elevator and ESI to inves in people, strengthen local operations, and support the long-term success of independent elevator service providers. Together, the organizations are committed to delivering exceptional service while creating new opportunities for employees, customers, and the communities they serve.
Darrin Middendorf added “Maven Group has supported American Elevator for many years, and their continued advice greatly enhanced my entrepreneurial and personal journey. After I decided to bring my company to market, Maven Group provided me with the opportunity to meet with various interested investors before it became clear that ESI was the best partner for our goals. Lastly, I was truly impressed with Maven Group’s ability to navigate the legal and financial diligence process, and with their invaluable contributions during the negotiation of the final purchase agreement.”
