Allan A McCallum
Director of Youth Competitive Swimming
Coach Allan McCallum joined the DSMY Marlins in June 2019.
Allan McCallum spent the past 3 years building the Women's
Swimming & Diving team at the University of Mary in North
Dakota. Starting the program from scratch, the team improved each
year under his guidance. In his last year at UMary, he helped
five swimmers achieve NCAA B cuts, two swimmers
qualified for the national championships and he coached
the conference freshman swimmer of the year.
McCallum joined the Marauders from the Central Iowa Aquatics
club program in Des Moines, Iowa, where he was the head coach the
past year after serving as the associate head coach for two and a
half years. In his time at CIA, the program won five state
championships, had a women’s sectional team title and was
twice recognized by USA Swimming as a Bronze Medal Club (2013,
2014). McCallum worked with seven Junior National Qualifiers and
one Olympic Trial qualifier.
Before joining the Central Iowa program, McCallum was the head
coach of the Rapid City (S.D.) Racers Swim Club from 2010-12. In
two and a half years, four swimmers qualified for Jr. Nationals,
three for Sr. Nationals and was recognized as a bronze medal
club by USA Swimming.
McCallum spent two seasons as a graduate assistant coach at
Northern State in 2008-10. While there the Wolves broke 56 school
records and produced two NCAA Division II provisional qualifying
times. Additionally the team posted a team grade point average over
3.50 each semester. While at NSU, McCallum also worked with the
Aberdeen (S.D.) Swim Club as an assistant coach.
A native of Bozeman, MT., McCallum was a high school honorable
mention All-American in 2001 and 2002. He swam collegiately at
Texas Christian from 2002-2006. While swimming for the Horned
Frogs, Allan was a team captain senior year, a first-team
All-Conference USA performer in 2003, 2004 and 2005 and helped TCU
win league championships each of those same seasons. The TCU
Freshman Swimmer of the Year in 2003, he also earned team awards
for most determined (2004), most dedicated (2005) and most valuable
team contributor (2006).
He began his coaching career after completing his collegiate
eligibility, serving as a TCU student assistant in 2006-07. He
returned home as an assistant boys coach at Bozeman High School for
the 2007-08 season and helped the boys team place second and the
girls team fourth at the Montana state meet.

Ankeny/Wellmark Practice Site Head Coach
Coach Bob has been with the YMCA of Greater Des Moines since
late 2014 and is the Head Coach for the Ankeny practice site. Prior
to coaching the Aquahawks, Bob was a graduate assistant coach with
Iowa State University. Bob received his BA in Journalism/Mass
Communication and Education Certification from ISU. Bob has a
strong personal background with swimming. He was a four-year letter
winner as a member of the Iowa State Men’s Swimming and
Diving Team and a member of the 1995 Big 8 Championship Team. Back
in high school, Coach Bob was received All-American Honorable
Mention in the 50 Free (which he considered his best event, yet the
100 breast was his favorite!).
Coach Bob believes that coaching has the ability to affect the
lives of children in a positive manner. Sport teaches lessons in
teamwork, integrity, dedication, sacrifice and humility and I
believe that delivering those lessons is tantamount to helping our
swimmers achieve athletic success. My goal is to develop young
people who enjoy swimming and are healthy in mind, spirit and body.
He enjoys spending time with his family; wife Susin and
children: Joe, Jaycin (JJ), Sydney, Chloe, Maia, Alanna and his
pets; Tigre (cat), Chaos and Havok (Siberian Huskies). In his spare
time, you can find Coach Bob enjoying one of his favorite hobbies;
reading, basketball and video games.
