Ally Walker was born in Tullahoma, Tennessee and raised in Santa Fe, New Mexico. She studied biology and chemistry at the University of California Santa Cruz and later worked for a genetic engineering firm in San Francisco.
During her time at Richmond College of the Arts in London, Ally became interested in theater, but she did not pursue it as a career, instead choosing to focus on her education in the sciences.
After graduating with a science degree, Ally continued to work in genetic engineering, but her life took a dramatic turn when a producer discovered her in an L.A. restaurant and cast her in her first project.
From that point on, Ally made her mark in both television and film, starring in daytime's Emmy-winning Santa Barbara (1984) and True Blue (1989),followed by the cult classic Singles (1992) and the action flick, Universal Soldier (1992).
Ally then returned to TV, playing a private eye in the series Moon Over Miami (1993). It was during this time that Ally was offered the opportunity to test for both "Rachel" and "Monica" for NBC's Friends (1994),choosing instead to take on a different type of comedic role in the film Steal Big Steal Little (1995),starring alongside Andy Garcia and directed by Andrew Davis.
Although Walker has appeared in a number of big screen films, she is popularly remembered as "Ashley Bartlett Bacon", Peter Gallagher's girlfriend in While You Were Sleeping (1995).
Her most notable role, however, was that of "Dr. Samantha Waters" in Profiler (1996),where she played a forensic psychologist with a dark past. The show was a pioneer in what is now the forensic drama phenomenon, and combined the standard "whodunit" with an intuitive/psychic twist which changes the landscape of television.
Some have compared Ally to Leigh Anne Tuohy, who was portrayed by Sandra Bullock in the film The Blind Side (2009),for making her documentary, "For Norman...Wherever You Are". Shot in 2005, it chronicles Ally's experience through the Los Angeles Foster Care System, a journey that she was inspired to take after helping a one-year-old baby and his mother get off the streets.
The film exposes the errors in the system, but never loses sight of the fact that the system itself is necessary. This heartfelt project won Best Documentary Feature at the San Fernando Valley International Film Festival, as well as the Champion of Conscience Award at Wine Country Film Festival.
Ally returned to the small screen in HBO's "Tell Me You Love Me" (2007),a show that holds a special place in her heart. It was an honest depiction of people in relationships, filled with scenarios that were tender and raw.
"To explore intimacy in such an honest, brave way was a dream come true for me", Walker says. "I had been brought up on the films of the 1970s, and the material we were given on the show was sort of a throwback to a time when films were about people, not care explosions".
Ally also continued to be seen on the big screen, most recently starring in Toe to Toe (2009) and Wonderful World (2009),alongside Matthew Broderick.
However, in a complete about face, Ally can now be seen as the sociopath, "ATF Agent June Stahl", on Sons of Anarchy (2008),FX's dramatic hit series. Originally cast for three episodes by the show's creator, Kurt Sutter, Ally has been recurring every year, and is now on her third season.
Walker has supported the Environmental Defense Fund and CYFC - Children Youth and Family Collaborative, among many other children's organizations. She resides in Santa Monica with her husband, three boys John Walker, William, Caleb, and her three dogs - Flora, Daisy and Flower, 2 mutts and a Rottweiler.
