On her appointment, Allen said: "I’m delighted to be joining such an iconic venue at such a pivotal time for the business.
"The SECC takes corporate business seriously and there is a great opportunity to encourage the sector to benefit from the facilities and infrastructure around the SECC. Add to that an award-winning venue team and it’s an exciting prospect I’m really looking forward to."
Kathleen Warden, director of conference sales at the SECC, added: "We've had some brilliant, high profile corporate events over the last few months, from Clydesdale Bank to Heineken. The venue is making significant leaps forward following a landmark year.
"We continue to look at the very best people to help us grow the business; Samme is a best in class professional and is the perfect fit for our ambitions."
