NORRISTOWN, Pa. (CBS) — After 23-years in the Montgomery County District Attorney’s office, including eight as the county’s top prosecutor, Risa Ferman is heading to the bench as a Common Pleas Court judge.

Her proudest accomplishment in her time as DA, Risa Ferman says, is the changes her office made to help protect victims, especially, she says Mission Kids, the child advocacy center.

But after 15-years in a leadership position in the office as first assistant and then as DA, she says she won’t miss always having her phone at her side.

“The office really does come before most other things in life as a practical matter, you can’t just turn off the phone and figure it will go away or someone else will handle it.”
