Tiffany Coll was named the 14th head coach in AU Women's Basketball history on June 7, 2022, after nine years with the program, including four as associate head coach. A vital member of the most successful staff in program history, Coll helped lead the Eagles to an overall record of 160-106 (.602), including 105-48 (.686) in the Patriot League. Among those victories were the program's only three Patriot League Championship titles, three regular-season PL titles, and five 22+ win seasons. She also helped guide the program to its only three NCAA Tournament appearances along with two WNIT berths.

“We are thrilled to announce the hiring of Tiffany Coll as the next head coach of the American University Women’s Basketball team,” said Walker. “Tiffany has been an integral part of our recent success and is a skilled recruiter, coach, and leader of young women. Her wealth of coaching experience and commitment to the values and mission of AU Athletics will be of great benefit as the program moves forward under her leadership.”

“I am incredibly honored and grateful to be selected as the head coach of women’s basketball at American University,” said Coll. “Thank you to President Burwell, Dr. Billy Walker, Josephine Harrington, and the rest of the AU selection committee for the opportunity to lead a tremendous group of young women. I look forward to continuing to meet and exceed the established tradition both on the court and in the classroom. The same principles by which I live my life – hard work, discipline, and relentless attention to detail – will be the foundation for future championships. My husband Dan, son Chase, and I look forward to this journey toward cutting down more nets with our American Women’s Basketball family.”

Coll was crucial in the development of one of the program's top players in recent years with Cecily Carl. Carl graduated in 2019 as a Patriot League Player of the Year, PL Scholar-Athlete of the Year, and one of only three players in program history to register over 100 blocks, 500 rebounds, and 1,000 points during her career. 

With her on staff, the American developed some of the best players to ever wear the AU uniform, including five Patriot League Scholar-Athletes of the Year, four PL Players of the Year, two NCAA Woman of the Year nominees, an NCAA Postgraduate Scholarship recipient, and a CoSIDA Academic All-American. She also helped mentor 28 All-Patriot League selections and nine Academic All-League honorees.

Prior to her arrival at AU, Coll spent the 2012-13 season as an assistant coach and recruiting coordinator at Towson. While at Towson, she helped to aid in the development of two All-CAA honorees and oversaw their academic performances, seeing marked improvements during her time with the Tigers.

Coll previously served as an assistant coach at Lehigh, helping guide the Mountain Hawks to three 20-win seasons, three Patriot League regular season titles and two NCAA Tournament appearances. Before joining Lehigh, she was an assistant coach at Navy for the 2007-08 season and was a graduate assistant coach at St. John’s for two seasons, helping the Red Storm to a top-25 ranking and 22-8 overall record in 2005-06.

Coll played basketball abroad in Portugal, Germany, Holland and Wales after playing at the collegiate level for UMBC. She was a four-year member of the Retrievers’ squad and served on the NCAA Student-Athlete Advisory Committee for two seasons.

Coll graduated from UMBC in 2003 with a degree in issues and athletic administration and received her master’s degree in sociology from St. John’s in 2007.
