Greenstone Properties hired Chris Schoen as a co-principal of the company to work with real estate veteran De Little.
Schoen spent 15 years as CEO and vice chairman of Barry Real Estate Company.
"The real estate business is moving in a new direction with a new platform," Schoen said in a statement announcing the move. "It is much more institutionally driven now. We are going to cater to this sphere of influence, broaden and deepen the right relationships and be full service in terms of what we can offer to our institutional contacts and others."
Little founded Greenstone after leaving Pope & Land in 2005.
Harvey Rudy, senior vice president of Barry Real Estate, will also join Greenstone.
