Walker joined Fullerton in August of 2021 after he completed his eighth season as an assistant coach with the Sacramento State Hornets in 2020-21, having also spent two years (2011-13) as the team’s director of operations.

Walker helped guide the team to its second consecutive Big West Tournament Championship Game appearance in 2022-23, following a six game winning streak to end the regular season and tournament wins over Hawai'i and UC Irvine. The squad went 20-13 overall and 12-6 in Big West action. 

In his first year with the Titans in 2021-22, the Titans went 21-11 and 11-4 in conference play on their way to winning the Big West Tournament Championship to secure a berth in the NCAA Tournament for the fourth time in program history.

With Walker on the staff, Sacramento State has won at least 13 games seven times in the last nine years, the first time that has happened since the program accomplished the feat seven straight years from 1966-73. In addition, the Hornets have won at least one Big Sky Tournament game in five of the last seven years (2015, 2016, 2017, 2019, 2020). Prior to 2015, the program had won just two Big Sky Tournament games in its first 18 years in the conference.

One of those Big Sky Tournament wins came during the 2019-20 season when the team finished 16-14 overall and 8-12 in the Big Sky. The Hornets won their first round tournament game over Weber State, before their quarterfinal game against Eastern Washington (and the rest of the tournament) was canceled because of the COVID-19 pandemic.

The 16 wins were the second most in the program’s Div. I era (1991-pres.), and the team finished with an overall record above the .500 mark for just the second time in the Div. I era. In addition, the Hornets’ defense ranked fifth in the nation (among 350 Div. I playing schools) and first in the Big Sky, allowing just 59.7 points per game. That was the best mark for the program since the 1962-63 season. Also, the program’s +3.8 rebounding margin per game was the best mark since the 1975-76 season.

Walker was also part of a staff that saw the 2014-15 squad post a 21-12 overall record and a 13-5 mark in the Big Sky Conference while securing the program’s first postseason appearance in the Div. I era (1991-pres.), and the team’s first postseason victory in 53 years.

The Hornets have also established a homecourt advantage that has seen the program post a 82-38 combined record (.683 winning percentage) inside the Nest since the beginning of the 2012-13 season. Also, during that time, the team is 51-31 (.622) at home against conference competition.

The Hornets’ overall record of 21-12 during the 2014-15 season marked the first time in the Div. I era that Sacramento State finished above the .500 mark, and first time since the 1988-89 season. In addition, the 21 wins tied for second most in program history (1948-pres.), and the 13 conference victories were the most in school history (regardless of conference). All of this from a program that had entered the 2014-15 season with just three winning seasons in the previous 38 years.

After reaching the semifinal round of the Big Sky Tournament, the Hornets qualified for the 2015 CIT Postseason Tournament, marking the first time the program had qualified for a postseason event since the 1988 NCAA Div. II Tournament, and just the fifth postseason appearance in school history. Sacramento State’s 73-66 victory at Portland in the first round of the CIT marked the first time in 53 years the Hornets had won a postseason game.

Off the court, the Hornets have excelled in the classroom during Walker’s tenure. In fact, as of May of 2020, the Hornets were the only men’s basketball team from a public school in the state of California to earn NCAA Public Recognition honors. The award is given annually to institutions for having Academic Progress Rate (APR) scores that rank among the top 10 percent nationally. Not only are the Hornets the only public school in the state to achieve the award, they received the honor four straight years (2017-20).

In addition, the Hornets have a team overall grade point average of 3.001. Prior to 2014, the men’s basketball program had never posted a 3.0 gpa during any semester in school history.

Perhaps the most impressive of the academic accolades - of the 36 Hornets that have expired their eligibility during Walker’s tenure, 35 have graduated. Five Hornets - Brandon Davis, Ethan Esposito, William FitzPatrick, Bryce Fowler and Spencer Monteiro - graduated in the spring of 2021.

During his first season as a full-time assistant in 2013-14, the program showed signs of taking off when the Hornets not only posted a then school-record 10 conference wins, the team also clinched a Big Sky Tournament berth for the first time since 2006 and won 11 home games. One of the season’s highlights included Dylan Garrity’s 75-foot shot at the buzzer to defeat Weber State, and instantly gain national exposure for the program. Video of the shot went viral and was named the No. 1 play on ESPN SportsCenter’s Top 10 Plays that evening.

The Sacramento native spent the 2010-11 season as an assistant coach at Rocklin’s Sierra College, and also served a year as a graduate assistant at Oklahoma in 2007-08.

During his two-year playing tenure at Oklahoma (2005-07), Walker appeared in 43 games, including 10 starts. He was named the team’s defensive player of the year as a senior, and helped the Sooners to an NCAA Tournament appearance in 2005-06.

Prior to Oklahoma, Walker played two years for Delta College (2003-05). As a sophomore in 2004-05, he was named the Northern California Junior College Player of the Year, first team all-state and first team all-conference after leading the squad to a 30-2 record, a 24-game winning streak and a semifinal appearance at the California Community College Championships. Walker was also named first team all-league during his freshman season.

He prepped at Sacramento’s Foothill High School where he was named first team all-state and the Central Valley Conference MVP as a senior after helping the Mustangs to a state title.

Walker graduated from Oklahoma in 2008 with a liberal arts degree.
