Eric Delabar is in his 25th season at Maryville and his sixth season as an assistant coach after guiding the Maryville University women's soccer team for 19 seasons. He joined the Saints in 1999 and led them to a 168-162-27 overall record. Delabar led the Saints to their first appearance in the Great Lake Valley Conference postseason tournament in 2017.

In his first year at the helm of the Saints program, Delabar led the women to a St. Louis Intercollegiate Athletic Conference (SLIAC) Tournament and Regular Season Championship. It was also the first time in the history of the program that they received a bid to the NCAA Division III Tournament.

In 2002, Delabar took over the Maryville men's soccer program and coached them to a 33-73-6 (.321) record in six seasons. Delabar also coached Maryville's first Great Lakes Valley Conference All-Conference selection as Lauren Dieckmann was named third-team All-GLVC in 2009, Maryville's first season of competition in the conference.

During the 2012 season, the Saints women's soccer team earned the GLVC Student-Athlete Advisory Committee's Sportsmanship Award. The squad also earned the NSCAA team academic award for the fourth straight year. Under Delabar's guidance, goalie Jena Casagrande earned the team's first GLVC Player of the Week award when she was recognized for her efforts ending the week of Sept. 24, 2012. In 2013, Shannon Foley was Maryville's first All-Conference selection and she repeated her All-GLVC honors in 2014. The Saints also posted their most successful season since joining the GLVC in 2017 as the Saints posted a 7-4-3 record and qualified for the GLVC tournament before falling to McKendree, 1-0 in the semifinals. Alex Johnson was the Saints' first conference award winner as she claimed the Freshman of the Year award in 2017.

He holds a USSF National "A" coaching license and has also served as an assistant soccer coach at Washington University in St. Louis and Saint Louis University. At the high school level he was the head boy's soccer coach at Fort Zumwalt North High School from 1989-98 and continued to serve as the head girl's soccer coach until 2013.

As a student-athlete at Quincy University, Delabar earned All-American honors as a goalkeeper, while also helping lead the Hawks to three National Championships. He graduated from Quincy in 1979 with a bachelor's degree in History. Upon graduating, Delabar extended his playing career to the professional level with both the New York Cosmos and the St. Louis Steamers.

In 1989, Delabar was inducted into the Quincy University Athletic Hall of Fame, and in 2002 he was inducted into the National Association of Intercollegiate Athletics Soccer Hall of Fame.

In the offseason, Delabar acts as director of the Maryville Saints Soccer Camps, while also holding a separate goalkeeper's camp.
