Professional Summary

Working alongside the office tenant and landlord representation brokers of Colliers International | Chicago’s Suburban Office Advisory Group, I provide our clients with customized reporting and analysis. As the research manager for the Suburban Office Advisory Group, I specialize in the collection and analysis of market and economic related statistics and prepare quarterly market reports for the overall suburban office market and individual submarkets.

I provide detailed market knowledge through the collection, organization and distribution of primary data including lease comparables, tracking tenants in the market, large-block availabilities as well as creating drive-time and demographic analysis and competitive building skyline reports. My more than 20 years of real estate experience have made me an integral asset to the team.

Prior to joining Colliers, I spent 10 years with CoStar managing the Chicago tenant division. During my tenure, I was responsible for the overall comprehensiveness and quality of a database of 50,000 tenants.


In 2013, I achieved the Commercial Property Research Certification (CPRC), which requires more than 25 hours of online coursework. CPRC offers a professional development path to increase strategic and tactical expertise in research, knowledge of the real estate industry and capabilities with the required tools.
