Peter Thonis, one-time chief communications officer for Verizon Communications, has joined RLM Finsbury as senior advisor focused on corporate reputation, crisis and brand building.

Walter Montgomery, CEO of RLM Finsbury, said the phone company vet, expertly guided it through a “myriad of delicate situations including multiple mergers and spinoffs, while building the strong brand and corporate reputation the company enjoys today.”

Thonis had handled Verizon’s global PR since its start-up in 2000. He retired from the company in July.
