His first coaching experience was at
Alief Elsik High School in Houston. He then became an assistant to
Ray Alborn at
Rice University. Following Alborn's dismissal in 1983, Helduser dropped out of the collegiate coaching ranks for a couple of years. In 1986, he was hired by
John O'Hara to coach the
quarterbacks,
wide receiver, and
offensive linemen at Southwest Texas State University, and stayed on in that position when O'Hara was replaced in 1990 by
Dennis Franchione. Altogether, Helduser spent 11 seasons coaching at Southwest Texas State University. He assumed the role of head coach when Franchione left after the 1991 season, and remained in that position until 1996. In five seasons, he compiled a 20–34–1 total record. He was replaced by
Bob DeBesse, with whom he later coached at
Texas A&M University. After one year as head coach at
Lake Travis High School in Austin, Helduser was approached by Franchione to join his staff at
Texas Christian University as offensive line coach. His job was coaching the offensive line blocking for future
NFL Hall of Fame running back
LaDainian Tomlinson. After an 11–1 winning season at Texas Christian University and two
Western Athletic Conference championships, Helduser left with Franchione to coach at the
University of Alabama (ending in a 10–3 season) and later, Texas A&M University. In his collegiate coaching career he produced many nationally recognized and NFL athletes and was renowned for his experience in recruiting. He left Texas A&M in 2007 to become offensive coordinator for Bryan High School in Bryan, Texas. He retired from football coaching after the 2009 Bryan Vikings football season. ==Death==
