(Bloomberg) -- John Egan’s business is helping people plan for retirement. So it was logical he’d make moves to prepare for his own. Egan struck a deal in 2016 to sell a majority of his firm to HighTower Advisors, a private equity-backed aggregator of registered investment advisers who collectively oversee more than $70 billion. HighTower now manages back-office arrangements for Egan’s Madison, New Jersey, office while he spends more time recruiting clients and works out with a personal trainer. Since the deal, Egan’s assets under management have soared 50% to $475 million and he’s lost 15 pounds.
