About Cathy

After nearly 25 years of helping people buy & sell real estate, I still love what I do. I can sincerely say that I most love removing obstacles so seamlessly that, often, the client never even knew they existed in the first place. I am a licensed broker in both Missouri & Illinois and can navigate a deal like nobody’s business. I love to work with a seller or buyer who knows what they want & simply needs a professional to get them there and to enjoy the journey. With special expertise in listing pricing, the first time home purchase process, and residential investment property I am ready to help.
