Casillas was born as one of eleven children to Mexican parents in Oxnard, California.^[2] She took up taekwondo at the age of fifteen when the church she attended began offering self-defense classes. After the classes were discontinued, she began training in Hwa Rang Do and then American Kenpo karate. It was at her karate school where she was introduced to kickboxing.^[3][4]

After going 6–0 with all of her wins by knockout as an amateur, Casillas turned professional in 1977. On June 13, 1979, after winning her first eight professional full contact karate fights, she defeated Karen Bennett by unanimous decision at the Grand Olympic Auditorium in Los Angeles, California to win the WWBA World Bantamweight (-53.525 kg/118 lb) Championship in what was her professional boxing debut.^[2]

Later that year, on December 23, she beat Irene Garcia to take the WKA Women's World Bantamweight (-53.5 kg/117.9 lb) title in Las Vegas, Nevada. This made her the first person to hold world titles in boxing and kickboxing simultaneously.^[5]

In a controversial bout in Chicago, Illinois on October 6, 1981, Casillas went the distance with Cheryl Wheeler. Initially, it was announced that Wheeler won on the judges' scorecards to take the WKA bantamweight title but it was later overturned to a win for Casillas.^[2]

She retired undefeated in 1986 with a record of 31–0, 18 KOs.^[6]

After, retirement Casillas taught martial arts at Oxnard College. She also pursued a different career route when she decided to go into the counseling department at Oxnard College. Now, Casillas is the Counseling Dept Chair at Oxnard College, and occasionally teaches courses in the PE Department.^[7]

Casillas has spent the years following her retirement from competition developing her own eclectic martial art of Shen Chun Do, "the way of the warrior spirit".

Originally a student of taekwondo and full-contact karate she earned a 3rd degree black belt in Kenpo as well as Kodenkan Jujitsu. Casillas trained under Grandmaster Angel Cabales and became the first woman instructor for Cabales Serrada Eskrima. She later studied Jeet Kune Do under Sifu Dan Inosanto and Arnis under Grandmaster Bobby Taboada and her husband Sensei Ernie Boggs.^[8] She has been President of the United States Sport Jujitsu Trade Association and an assistant coach to the USA Jujitsu Team. She was awarded Black Belt Magazine's and Inside Kung-Fu Magazine's "Woman of the Year" in 1989 and inducted into the Martial Arts Hall of Fame. In 2020, she was inducted into the International Women's Boxing Hall of Fame.^[9] She has been credited as the designer of the Boxing Skirt.^[10]

In 1996 Casillas designed a knife known as the Ladyhawk, manufactured by Masters of Defense (MOD) as a collaboration with Microtech Knives and marketed as a self-defense knife designed for women.^[11] Impetus for this design came after Casillas stabbed one of two attempted rapists, using the thug's own knife after disarming him.^[12]
