Professional Summary

As a Senior Brokerage Associate with Colliers International | South Carolina, my focus is local office brokerage, which includes landlord and tenant representation as well as buyer and seller representation.

I have over 40 years of experience in the Richland and Lexington county business community and I strive to bring a positive attitude and passion for the Columbia area and its attributes. As a problem solver with “big picture” vision, I have a reputation of providing considerate and thoughtful service to a multitude of clients. My professional and personal strength is networking and developing relationships. I possess extensive experience in working with small business owners, professional service providers and non-profits.


My leadership and service has resulted in multiple commendations from local and statewide organizations. I have been a recipient of the “Circle of Excellence” from the CCRA multiple years for top commercial leasing and sales transactions. I am a recipient of the President’s Excellence Program Award from the Central Carolina REALTORS® Association. I have also received the Community Impact Award from the United Way and The Women in Industry (TWIN) Award.


I have worked with Colliers International | South Carolina for over 10 years. Prior to working at Colliers, I was the Senior Managing Director for CBRE Columbia for 12 years. I also served as a commercial lender and business development officer for several banking institutions for 18 years prior to my move into commercial real estate.

“Mary Winter knows Columbia and she definitely knows commercial real estate! When we spun our practice off from our previous firm, Mary Winter was there for us. She spent several meetings getting to know us, what our needs were, and then flawlessly executed, in a condensed time frame, to put us in the perfect space to launch out new company. I would highly recommend her to any professional looking for office space.”
