Callie Brownson is the chief of staff for Browns first-year coach Kevin Stefanski. Brownson played eight seasons for the D.C. Divas of the Women’s Football Alliance and is a two-time gold medalist for USA Women’s Football.

“Callie is uniquely situated where she can go interact with football ops or PR or the locker room or the equipment room,” Stefanski said before the season started. “She’s really the liaison to the rest of the building for me. I’m going to lean on her heavily and already have.”

Jennifer King is a coaching intern for Washington. She is working with the offense and is specifically working with running backs coach Randy Jordan. She’s coached in the Alliance of American Football and for Dartmouth College.
