Mercer Advisors announced Monday that Dave Barton, its long-term executive and current head of mergers and acquisitions, has retired.
Barton's retirement is immediate, a spokesperson confirmed via email correspondence with ThinkAdvisor, and he stepped away to focus on his health. Martine Lellis, principal of M&A partner development, will take on his responsibilities.
Barton joined the company in 2000 as general counsel, with subsequent roles as chief operations officer and president. He became CEO in 2008 and held that role through 2017, when he stepped down to serve as lead of M&A as vice chairman.
