Jason R. Ziegler
President
Jason has more than 12 years of WMS experience implementing the RedPrairie/JDA product suite and other WMS products while working for a third party logistics provider, a tier-one WMS provider, and in private consulting. His time at Exel/DHL laid the functional and operational groundwork for a successful technical services career at RedPrairie where he learned software development best practices and the intricacies of supply chain software.

However, his ultimate desire was to build software in poorly served areas of the supply chain and offer more customer-focused services for not only the RedPrairie community, but also the supply chain industry as a whole. This dream paved the way for the creation of MacGregor Partners in 2012.

Jason’s love for technology and supply chain has been instrumental in the growth and direction of the company, taking it from one employee to its size and breadth of consulting and software offerings today.

Beyond Nicolas’s numerous technical skills from his time as a developer, he brings real-world operational expertise from his time within industry that sets him apart from his peers.
