Beach returns to returns to his alma mater after a four-year stint at Longwood University as an assistant coach. He will be the Director of Baseball Operations under new head coach Kevin Schnall.
Beach joined Longwood in the summer of 2021 from his alma mater at Coastal Carolina, where he had spent the past five years on staff alongside Oxendine and under 1,200-game winner Gary Gilmore. In that time, Beach served as both a graduate assistant and a student manager and helped the Chanticleers win a pair of Sun Belt titles, including the conference tournament in both 2018 and 2019.
Beach coached Hunter Gilliam at Longwood. As a Junior, Gilliam posted a .986 percentage in the field before Mickey played a part in Gilliam posting a perfect 1.000 fielding percentage as a Senior at Longwood. Hunter received all-conference honors as a Senior. From there, Gilliam moved on as a graduate to the University of Kentucky, where he made an all-defensive team in his lone season with the Wildcats.
 During conference play, Longwood notched its highest-ranked win in program history. The Lancers took down No. 14 Campbell on April 15 in a 6-3 win. It was the first time the team had won a ranked game since 2016 and the first time the Lancers had beaten a program in the top 20.
As a graduate assistant at Coastal Carolina, Beach earned a pair of master's degrees in three years while also fulfilling coaching duties that included assisting infielders and liaising with the analytics team. He also directed the student managers, developing their schedules and responsibilities.
