During this time Garrick learned and refined his management, sales and customer service skills. Garrick became a front runner in the QIP and TQM processes making their way into the refrigeration and HVAC industry and uses these processes in all aspects of his operations to this day. In 2004 he left Hussmann and Joined Shumate Mechanical Services Orland Inc. and spearheaded their initiative to start a branch offering refrigeration, EMS, and HVAC in Florida.
