"At a time in the industry when owners are demanding a complete line of value-added services, Brian and Grant will be an integral part of our full-service approach to institutional and local clients," says Jonathan Kingsley, managing director and executive vice president.

DiRienzo, who has more than 20 years' commercial real estate experience in investment sales and consulting, previously was a senior investment adviser with Marcus & Millichap.

"As more clients expect their real estate services firm to provide national and international coverage, moving back to Grubb & Ellis offers the opportunity to considerably augment the services I can provide," DiRienzo says. He will be located in the company's Boca Raton office.
