Chandler, who was at Beattie for two years, has been appointed as a director and left Beattie last week.
He was previously a director at Bell Pottinger Financial and a senior account manager at GCI Financial.
Chandler said he made the move to handle bigger clients, having worked primarily on Beattie's small-cap business.
His experience is primarily drawn from IPO work. At Beattie he worked for ZOO Digital Group, Alliance Pharmaceuticals, BBI and Epic Group.
Beattie Communications MD Gordon Beattie said he had now scrapped Chandler's position.
