Maier, previously the company’s board director of development, will now lead TFI across all areas of operation in the newly designated role.
After the group reported stable financial results last week, Maier outlined plans to add services and make acquisitions.
He said: "TFI’s mission is to help clients engage with their audiences. We fully understand the value of events within that engagement and are extremely good at helping deliver events that really match to client objectives.
"We want to grow the things that we do very well and add more to our offer. We will deliver the full events circle for our clients, rather than, for example, event management and logistics alone. We have identified a need for additional services where the client can benefit from our co-ordinated management of quality and delivery. This could well involve acquisitions and also international expansion. This is a hugely exciting time for TFI Group."
Peter Franks, TFI Group chairman and founder, added: "I'm delighted that someone of Simon's vast experience has agreed to lead the business. The next three or four years will see huge growth and changes in the events market, and we too are growing carefully and modestly to match, and stay ahead of, client needs.
"Such growth needs a good and steady hand on the tiller. It also requires robust planning and skilled leadership. Simon will provide all of these attributes. He's also enormously creative, both from a corporate point of view and also in how we can shape and build the business."
TFI recently held an incentive trip in mexico for tequila brand Jose Cuervo.
