When it comes to her work in television, Kim Delaney has a lot more credits on her resume than just playing Severide's mom on "Chicago Fire." While the actor has been featured in a number of big-name shows, her most notable claims to fame arguably include "All My Children," "CSI Miami," "NYPD Blue," "Army Wives," and "General Hospital." Besides her talent, Delaney's attitude toward her craft has arguably been the driving force behind her longevity in the business.

Even though every part she plays is different, Delaney believes all the roles she has taken on have provided a unique challenge and that each one has only helped her grow as an actor over the years. "I think every role is just different. I don't know that there is easier or harder. I think it's just all evolving as the years go on," she said in a 2009 interview with Avi the TV Geek for WOOD TV8. While it's evident that her experiences in front of the camera have taught her much, she has also managed to garner a wealth of knowledge since her early days in the game from those around her. "My first acting job was All My Children," the actor told the Digital Journal. "I've been so fortunate to work and learn alongside some of the best writers, producers, actors, and even crews have taught me so much."

Based on the actor's accounts, Kim Delaney's robust career may not have been possible had it not been for her ever-evolving passion for acting and unwavering devotion to cultivating her skills.
