The company’s chairman, David Gilbertson, approached Gill following former CEO Teresa-Ann "TA" Dunleavy-Bell’s decision to depart the business.
"I accepted the role since my past experience in the business ensures that I can hit the ground running at a busy time, as we approach the Christmas season," he said.
Gill explained the CEO role is a temporary one. He is currently working on creating a business plan, which his successor, who will become permanent CEO, will take over when the time is right.
"My remit is to ensure a safe transition to the next permanent CEO and to deliver an exciting business plan for the 2016/17 year, building on the safe and secure foundations that I have inherited.
"We have just signed the contract to take over the sales and catering at Winchester House and hope to be announcing two new long-term venue contracts in the next few months," he added.
Gill has previously held chairman, managing director and group events director roles at the company. Upon his return to the business, Gill has found that it is tracking particularly well.
"The company has been returned to profit and the senior management team has been streamlined following the departure of several founder shareholders over the past 18 months," he said.
"The management team has been reinvigorated by the arrival of key seniors including Tom Barrett, the new managing director at Create."
Gill will continue to fulfil his role as non-executive chairman at Story Events, a company that he noted is also delivering positive results.
"Our managing director, Sarah Kay has delivered huge growth over the past year and will be supported by her fellow directors Joanne Bates and Dominique Gill as the company enters its third year of trading in great shape," he said.
