Bill Siems specializes in new business development, third party tenant representation, landlord representation, property dispositions, and property acquisitions. Bill is currently focused on new market rollouts and national store expansion programs for several up and coming as well as established brands.

Bill began his career in 2003 working for a large privately owned St. Louis developer, where he focused on shopping center leasing and tenant representation. In 2005, he transitioned to the mall world, working exclusively on the mall property portfolio for CBL Properties (formerly Westfield).

In 2013, Bill was hired by Rouse Properties, Inc. which owned and managed 35 regional malls and retail centers in 21 states encompassing approximately 24 million square feet. During his tenure, Bill oversaw 12 properties in the portfolio spanning Michigan, Illinois, Alabama, Arkansas, Louisiana, North Carolina, Maryland, Mississippi, and Virginia. 


Six years later, Bill refocused on the St. Louis market when Brookfield Properties acquired GGP shortly after its acquisition of Rouse, whose expansive portfolio included more than 170 locations across 43 states, representing over 150 million square feet of retail space. Bill managed St. Louis’ two highest performing malls, Plaza Frontenac and the St. Louis Galleria.

Throughout his career Bill has worked with local and national tenants alike from nail salons and local food court operators to H&M, Lego, Restoration Hardware, Amazon, Warby Parker, and Bath and Body Works.

Bill is a graduate of Truman State University and resides in Webster Groves, Missouri with his wife, their 4 children, and their dogs Titan & Zeus.


Forest Park; between the Zoo, the Art Museum, The Muny, the running trails, and just the general beauty of it all, some of my favorite memories of growing up and raising my own children happened there.
