Six top brokers from Harrison & Bates are joining a rival commercial real estate brokerage.

The six — including David M. Williams, the president and CEO of Harrison & Bates; and Steve Gentil, the firm’s chairman who has been a broker since 1980 — are joining Henrico County-based Commonwealth Commercial Partners.

Five of the six will become senior vice presidents of Commonwealth Commercial and one will be a sales and leasing associate. They will join the company June 1.

Besides Williams and Gentil, joining Commonwealth Commercial are Chip Louthan, Bruce Milam and Kit Tyler as senior vice presidents and Colton Konvicka as a sales and leasing associate.

“They are an established brand in the industry,” Mark Claud, the founder and CEO of Commonwealth Commercial, said about the new brokers.
