Genevieve Costello’s Story


Genevieve Marie Costello was born and raised in San Diego, CA to Paul and Myrna Costello. The youngest of four older sisters Minerva, Jennifer, Maria and Rose, Gen was born fearless and enthusiastic. Growing up in the southeastern suburb of Spring Valley, Gen followed in all of her sister’s footsteps and attended Mount Miguel High School.  There she would earn varsity letters in basketball, softball, golf and cross-country.  She was inducted into the Mount Miguel High School Hall of Fame along with her 2003 CIF championship girl’s basketball team, the first girl’s basketball CIF championship in the school’s history. She would lead Mount Miguel High School to four straight CIF championship appearances, and three titles.



Taking her talents to UC Davis on a basketball scholarship, Genevieve became the point guard and leader on the UC Davis women’s basketball team (2005-2009), helping the Aggies transition to Division I status. Genevieve played a part in the Aggies’ making the 2008 Big West Tournament Championship where they advanced to the Women’s National Invitational Tournament in UC Davis’ first year as Division 1. Gen would graduate with a degree in Human Development with plans to devote her time to making the world a better place.


Genevieve went on to attend UC Davis on a basketball scholarship. She was a stellar performer for four years and the Team Captain her senior year. In her four seasons at UC Davis, the Aggies earned a berth to the Women’s NIT in 2008 (losing in the first round to Cal in overtime), with Genevieve a huge component to the school’s elevation to NCAA Division I status. Genevieve also led the Aggies in assists in 2006-07, while ranking among the top 3-point shooting percentage leaders in school history. The program grew quickly, eventually winning the 2010-11 Big West Conference championship to earn its first NCAA Tournament berth. She graduated with a Bachelor of Science degree in Human Development.


With Genevieve’s infectious personality and love for life, no one could have predicted the devastating stage IV breast cancer diagnosis in April 2013. The hallways of the UC San Diego Cancer Center overflowed with Costello’s family and friends. At times seemingly taking over the entire floor, people would sit together and share stories while waiting for their chance to spend time in her room. While battling cancer and the fatigue of the treatment, Costello remained upbeat and inspiring to those around her. While Genevieve put up a fight, she would eventually lose the battle against this aggressive disease and sadly passed away less than a month after she was diagnosed at the age of 26.  Family, friends, teammates and fans will forever remember her competitive spirit, fearlessness, boundless enthusiasm and unconditional friendship.
