Throughout his professional career, Gregg Perelman has been a trend-setter. As CEO of Walnut Capital, he has brought his vision of innovation to bear in a city that is becoming synonymous with urban rebirth.

Gregg has been instrumental in creating and implementing Walnut Capital’s aggressive acquisition and development strategy. A hands-on developer, he often supervises construction and renovation projects in the field and takes prospective tenants on tours of apartments and townhouses. He jointly oversees the company’s property management arm, leading a staff of more than 100 people with vision and enthusiasm throughout the day-to-day operations, marketing, and management of all the firm’s residential, office and commercial properties. Gregg has built his career around attention to detail and changing the landscape of the city he calls home.

After co-founding Walnut Capital, Todd sought properties that appeared too difficult to rehabilitate for other developers. Driven by the question, “Would you live there?” he dedicated himself to doing what was needed to answer “yes.” His projects have infused the city with some of its most innovative growth. With collaboration, “You can do special things.”
