With a focus on tenant representation in the downtown Chicago office market, I have gained an extensive understanding of the real estate leasing process. My practice focuses on providing counsel for a diverse group of clients including law, consulting, marketing, financial services, trading and technology firms. With 16 years’ experience, I am an expert in developing and executing real estate strategies which maximize my clients’ economic outcomes, all while ensuring real estate is always aligned with the company’s short and long-term business operating objectives.
Prior to joining Colliers International, I spent nine years at Transwestern as senior vice president where I specialized in tenant representation. I began my real estate career at Insignia/ESG and later CB Richard Ellis following the merger of those two firms.
Office
Tenant Representation
"We have been a client of Corby Marx for over 10 years. I have never worked with a stronger team with more integrity that represents our interests exclusively. They strive to build long-term relationships not a transaction. Not a month goes by where I receive a call from other agencies that represent lessors and they pitch their edge on the market and how they are going to save us money. I tell them we work with Corby and they politely say, "you are in good hands." I believe it is important to work with individuals who are respected by their peers.
We will continue to be a long-standing relationship of this firm and this team!"

"Corby was very proactive in keeping is updated on changes in pricing and terms since the market was changing fairly rapidly. He worked with us to be creative about spaces we could consider, and he was a great help in bringing all the right parties together in building out our space. I recommend him highly."

"Corby and Joe were fantastic partners in building the next phase of our company. As a technology startup, we needed an office that provided an inspiring environment and the room to grow, and the guys were amazing in finding the perfect space. Corby and Joe understood our vision immediately and worked tirelessly to make it a reality."
