SAN FRANCISCO — Another group is peeling off from Sacramento firm McDonough Holland & Allen — effectively ending the hope that a smaller McDonough firm would emerge from its wind-down.

Southern California’s Best Best & Krieger announced it will be adding 18 municipal, land use and redevelopment attorneys in September, including partner Edward Quinn, McDonough’s chief executive officer. Also joining as partners are T. Brent Hawkins, Iris Yang and Harriet Steiner. All 18 will work in BBK’s Sacramento office.
