Grant Horn began his education at the University of Wisconsin-Milwaukee, graduating in 2003 with a bachelor’s degree in architecture and a master’s degree in architecture in 2005 from UWM as well. Gaining professional architectural experience, he worked for a small firm in Milwaukee during the summer and solidified the idea before grad school that architecture would not be his calling though his certificate in real estate development from UWM would prove useful in building a personal portfolio of investment properties. Like many other architectural grads, he found his way into a related field.
In 2005 he began working with J. F. Ahern Co., in the HVAC service department as a sales representative. While working he returned to school, earning a certificate in sustainable operations and completing fundamental HVAC courses at Milwaukee Area Technical College. Throughout his 15 years with Ahern he worked with many of the largest businesses in Wisconsin and in the United States, across just about every industry – mining, health care, energy, industrial, commerical, trucking and many more.
In 2007 he joined the International Facility Management Association and took an active role on the Membership Committee of the local Southeast Wisconsin Chapter. When the committee chair position was open he accepted that role and within a few years was elected president of the local chapter, which grew at that time to nearly 240 members, the largest chapter in Wisconsin.
Horn joined the UWM School of Continuing Education in 2019 and also started up his own business specializing in HVAC retrofits for light commercial applications.
