Riedel Communications has expanded its leadership team, with Marc Engroff joining as CFO.
With Engroff taking on the role of CFO, Frank Eischet now transitions into the role of chief operating officer, with an increased focus on group-level strategy and cross-functional alignment.
In this new role, Engroff will assume responsibility for key corporate functions including finance, controlling, M&A, global purchasing, and IT.
The move is being implemented following Thomas Ridel’s acquisition of ARRI, strengthening the management structure of Ridel Communications while also improving coordination and governance at the Ridel Group level.
Engroff takes over operational financial leadership within Riedel Communications, while Eischet will dedicate greater focus to overarching priorities across the Riedel Group, including strategic alignment, operational scalability, and the continued development of global structures. Eischet will continue to serve as managing director of Riedel Communications alongside Thomas Riedel, jointly representing both the company and the Riedel Group.
Thomas Riedel, CEO, Riedel Group, commented: “Frank has been instrumental in building the structures that have enabled Riedel’s growth over the years.
“With Marc, we are appointing a highly capable and trusted leader from our own ranks who combines strong financial expertise with a proven ability to translate data into strategic direction. This evolution strengthens Riedel Communications operationally while further developing our leadership at the Riedel Group level.”
Engroff joined Riedel Communications in 2024 and most recently served as Director Group Controlling, where he was instrumental in building and developing the company’s controlling structures and processes. Prior to joining Riedel, he held several finance leadership roles at Deutsche Telekom AG, where he worked in various controlling and transformation functions since 2008.
“I am very grateful for the trust that Thomas and Frank have placed in me,” said Engroff. “I take on this responsibility with humility, supported by my outstanding team, which has been with me along the way, and by many great colleagues across the organization. Looking ahead, I am excited to continue shaping Riedel’s development while ensuring we support its growth in a sustainable and resilient way.”
Eischet added: “Riedel’s success has always been a team effort. I am proud of what we have achieved together over the past years and grateful to have been part of this journey. With Marc taking on the CFO role, we are strengthening our operational foundation even further. I look forward to focusing more on the broader development of the Riedel Group and driving the next phase of our growth.”
