After three years at Hunt Mortgage, Dennis Young started Wednesday as a director heading Birdsey Group’s Irvine, Calif., office. He’ll spearhead an underwriting initiative for clients that originate debt via Freddie Mac’s small balance lending program. He reports to managing director Robert Burton in the firm’s Atlanta headquarters. Young was deputy chief underwriter of agency mortgage products at Hunt, also in Irvine. He previously worked at Centerline Capital, which Hunt took over in 2013, and at HomeStreet Bank.
