Bill Annan is entering his 11th season at Oklahoma State and his seventh as the program's associate head coach.
Annan previously served two years as a Cowgirl assistant coach from 2011-13, as well as two seasons as the program's director of player development, working in that capacity from 2009-11.
During his time in Stillwater, the Cowgirls have made five NCAA Championship appearances, including a Sweet 16 finish in 2014 and the program's first WNIT title in 2012. Annan played integral roles in recruiting, opponent scouting, post development and OSU's offensive and defensive schemes.
Â
In 2017-18, the Cowgirls advanced to the second round of the NCAA Tournament and produced a pair of All-Americans in Loryn Goodwin and Kaylee Jensen.
"Bill's work ethic has been an integral part of the growth and success of our program," Oklahoma State Head Coach Jim Littell said. "His experience, knowledge of the game and ability to motivate has helped make OSU basketball a staple in the postseason.
The 2015-16 Cowgirl squad finished the season 21-10, reaching the 20-win plateau for the fifth year in a row, making it the first such stretch in program history. The season ended with the fourth-straight NCAA Tournament appearance for the Cowgirls, which ties the longest string in program history.

Annan helped four former Cowgirls earn selections in the WNBA Draft, in addition to AP All-American recognition. This included guard Brittney Martin the 2016 Big-12 Player of the Year. He also helped three Cowgirls receive recognition on the Big-12 All-Freshman Team, along with forward Liz Donohoe the 2012 Big-12 Freshman of the Year.
On the recruiting trail, Annan helped the Cowgirls acquire national Top 100 recruits in 2012, 2013 and 2016, including Top 20 recruit Brittney Martin in 2012, according to ESPN.com's HoopGurlz. OSU has signed players from 10 states during Annan's tenure.
Annan joined the Cowgirl program after a successful run at Washburn Rural High School in Topeka, Kan. His tenure spanned nearly two decades and resulted in a career record of 303-109. Under his guidance, the Lady Blues won three state titles in 1996, 1999 and 2009, runner-up finishes in 1998 and 2004, and a third-place finish in 2000. Washburn Rural won 11 Centennial League titles in 18 years under Annan's leadership and made nine state tournament appearances. His teams reached the 20-win plateau six times, including a 24-1 mark in 1998 and 2009. He was inducted into the Washburn Rural High School Hall of Fame in 2015 for his coaching and teaching contributions to the school.
A three-time Kansas Basketball Coaches Association Coach of the Year, Annan was also a seven-time pick as the conference coach of the year. On five occasions, he was named the Topeka Capital-Journal City Coach of the Year. Annan was twice named the publication's state coach of the year and was named the Kansas Coaches Association Coach of the Year in 1999.
He began his coaching career in 1986 at Seaman (Kan.) High School where he served five seasons as an assistant for the boys' team.
Annan received his bachelor's in business education from Kansas State in 1986, before receiving his master's in educational administration from Kansas State in 1993.
Annan and his wife, Marcia, have two sons, Trent and Grant, both OSU graduates.
