"We changed a lot of the culture in the building," Holmgren said Saturday, according to the Milwaukee Journal Sentinel. "And that's easy to say -- and hard to do. That probably, to me, over the course of time, will mean the most."
Holmgren was in Green Bay to be inducted into the Packers Hall of Fame along with former Packers general manager Ron Wolf. Holmgren coached the Packers from 1992 to 1998, winning Super Bowl XXXI in 1996.
"I just think, how good are the Packers now," Holmgren added. "What's happened since 1992. As opposed to what had happened prior to 1992 for all those years. I just have to look at the stadium and walk through here. I mean it is unbelievable how things have changed.
"I had a little part of that -- a little thing to do with that and I'll feel good about that."
Wolf also extolled the job Holmgren did reversing the franchise's fortunes.
"What he did in those early years was incredible," the former GM said during Holmgren's induction ceremony.
