Jeavons' previous roles include group account director at Meeting Point Conferences and venue director at ICC Birmingham.
Peter Franks, TFI Group chairman, wished Jeavons all the best in his future career, adding that TFI has enjoyed several new business wins and has taken on additional staff this year.
He said: "The market is an exciting one at the moment for us and our three channels, pharma, association and corporate are very busy - not just now - but with committed business that takes us well into 2015 and beyond. We will focus on what we’re good at and we’ll also, of course, concentrate on our strengths in the UK and overseas markets. Expansion is definitely on the cards and we’re currently exploring links and opportunities in South America, South East Asia and North America."
