Bax Engineering Announces Leadership Transition as Dan Bax Named Incoming President

Fourth decade of service continues under next generation of family leadership

St. Charles, Mo. — Bax Engineering Company today announced a planned leadership transition as Dan Bax, son of company founder Harold Bax, will assume both majority ownership and the role of President effective January 1, 2026. Dan will work closely with Jeff Simmons to guide the company’s future growth and client service. Simmons will also take on an ownership role and serve as Vice President.

Dan Bax represents the next generation of family leadership, returning to the firm after building a successful 15-year career in the electrical utility industry. At Ameren and later at LUZCO Technologies, he managed multidisciplinary teams on large-scale projects in substation design, transmission and distribution systems, and underground electrical infrastructure. Known for his technical expertise, strategic planning, and collaborative leadership style, Dan has also spearheaded reliability programs to improve efficiency and customer satisfaction. He will succeed current and longtime President Cliff Heitmann.

“I’d like to emphasize the strong foundation that Cliff and my brother Dale have built over the past two decades,” said Dan. “Bax Engineering has earned a trusted reputation in St. Charles County because of the dedication of our engineers, designers, surveyors, and support staff – including Jeff Simmons, who has been an integral part of the company’s success. Jeff and I are grateful to be stepping into leadership together and are committed to carrying that legacy forward.”

Heitmann, who has been with Bax for 31 years and served as President for the past 19, will remain in his role through December 31, 2025, before retiring. 

“Bax Engineering has been an important part of my life, and I wanted to make sure the future leadership would be the right fit,” said Heitmann. “Dan brings a strong business acumen and new energy that complements Jeff’s experience and longstanding relationships with our clients. Together, they represent continuity and innovation for Bax’s future.”
