Appointees to two key town posts will soon be starting their tenures. Ronald San Angelo is expected to begin as the new town administrator late this month, while Michael Miksch, the new police chief, will begin July 31. San Angelo, a former mayor of Naugutuck, Conn., and a former Connecticut state representative, most recently worked for CGI as a program and project manager in information technology and businesses processes. He succeeds Rene Read, who resigned as town administrator effective May 12 to become town manager in Duxbury. Meredith Marini, executive assistant to selectmen, has been serving as interim town administrator. Edward Savage resigned as Hanson’s police chief effective last Oct. 4 after having been placed on paid administrative leave the previous month for unspecified reasons. Arthur Parker, a retired Carver police chief, has been serving as interim chief.
