Jake Shackelford Associate Performance Coach
Jake Shackelford, a native of Wauwatosa, WI, comes to MAC from the Jersey Wahoos where he spent the last 3 years as the Associate Head Coach. He assisted the National Team and Age Group program focusing on overall team development from novice to elite athletes.

Following his college career, he coached age group with Southwest Aquatic Team (SWAT) as the lead Junior (13-14) coach until 2017.
Jim Lohmeier Lead Coach Bronze & Blue

Jim Lohmeier began coaching swimming when his summer coach brought him on to train the 6 and Under group at the ripe old age of 13 back in 1977. In 1983 he became the head coach of Davis Monthan Air Force Base in Tucson, Arizona. He stayed with DMAFB for 4 summers, growing the team from 40 members up to 110. Along the way he started and trained a small group of athletes at a year round team he cofounded at La Mariposa Country Club. 

After graduating from the University of Arizona in the mid ‘80’s, he put coaching on pause and served in the United States Army. In 1990 he returned to the University of Arizona and became a K-8 certified teacher with the goal of teaching 8th grade and restarting his coaching career. He coached at Flowing Wells HS and then moved to his alma mater, Sahuaro HS where he was fortunate to coach a back to back state champion in the 500 free, who he learned a ton from. He also coached the summer team, Eastern Hills Orcas, from the fourth tier up to 3 peat winners at the top level of the Southern Arizona Aquatic Association. Eastern Hills had future state record holders, NCAA champions and even a 2012 Olympic bronze medalist in the ranks. 
In 2000 he moved with his family to Waunakee, Wisconsin, continued teaching and coached the boys and girls teams for 7 seasons each. He also founded the Waunakee Orca Warriors, WOW, which since evolved into the Waunakee Wave. In 2010 he took the helm of the Waterloo Swim Team where he coached for 5 years. H2OLOO had four individual state champions during that period. In 2015 he moved to Oregon as the co-head coach of OCSC. He became the Head Coach in the spring of 2016. In his 9 years in Oregon the Tigersharks won three Division 2 team titles, dozens of individual championships, three individual high point trophies and had swimmers set 6 state records. At the Junior Nationals meet in Irvine, California, he saw one of his swimmers get the Olympic Trials cut and finish the year as the top 15-16 year old 100 Meter Breaststroker in the country. 
Jim loves the adventures he’s had and striving to help the kids he coaches grow towards becoming women and men of excellence, in and out of the pool. He stays current on trends and technique through his involvement with the American Swimming Coaches Association but insists he’s learned the most from his swimmers and his mistakes along the way. 
He is ecstatic to join the MAC coaching staff to continue this adventure. 
Joseph Decker Assistant Coach
Joseph was born in Milwaukee, WI and raised in Brookfield, WI. Just recently rounding off his bachelor's degree as a double major in Psychology and Spanish at the University of Iowa, he now attends graduate school at UW pursuing a Master of Science in education and an EdS in School Psychology. Graduating from Brookfield East High School in 2019, he also swam competitively for 11 years, 8 of those being for Waukesha Express Swim Team (2008-2016) and the latter for Elmbrook Swim Club (2017-2019). Throughout his swimming career, he hasqualified for state, speedo sectionals, and NCSAs.
After leaving the sport competitively in 2019, he was offered a temporary coaching job at Elmbrook Swim Club for 3 months during the summer before leaving for college that upcoming fall, this sparked his passion for coaching competitive swimming. Beginning in the fall of 2020, he began coaching at the Iowa Flyers Swim Club as the lead Junior/Senior coach until 2023. There he led multiple swimmers to many lifetime firsts, such as state qualifying times and many personal bests. At IFLY, he was mentored by Nathan Mundt, who is now the University of Iowa women's swimming and diving head coach. There he learned many of his coaching skills through Coach Mundt and by watching how he connected with his swimmers.
Unlocking each swimmers full potential is very important to him; Joseph believes that swimming is a gateway to success, as the discipline taught implicitly and explicitly to swimmers garner positive outcomes in and out of the water.
