Running a business isn’t easy, especially when you’re married to the CEO. As President of THE INTERIOR DESIGN GROUP LTD., Chris knows a good relationship is key to a successful company. That’s why she goes out of her way to listen to clients and ensure they are happy. Chris views all clients as partners and works hard to earn their trust, which might be why there’s is such a high incidence of repeat business. As a co-founder of IDG, you can tell Chris truly loves what she does – from a follow up phone call to delivering a plate of homemade cookies, she knows how to keep a relationship strong… and that is good business.

Jessica graduated with an architecture degree from the Illinois Institute of Technology and is a fully licensed architect in four states. It can be said she’s not afraid to get her hands dirty both at the office and outside of work as she loves Jeeps and off-roading. One thing’s for sure, having Jessica on board certainly helps keep IDG in the fast lane for future success.
