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.

The first thing to know about Terisia is that there is only one of her. This is interesting because she seems to have the uncanny ability to be at two places at one time. A graduate from the Harrington Institute of Interior Design and an accredited LEED professional have put Terisia in heavy demand at IDG. And that’s the way she likes it.

Laurie Deconcilis

Senior Project Coordinator

Team Member Since 2005

ldeconcilis@idgltd.com

At first glance, interior design and hockey don’t seem to have much in common but after you get to know Laurie, you’ll find that her passions for both are what make her so unique. With over 17 years of experience in interior design and a degree from the school of the Art Institute in Chicago, Laurie has been a great asset to IDG. Laurie’s approachable manner is only matched by her expert approach to colors and finishes in which she takes great pride. The fact that she plays hockey in her spare time gives her a rare perspective on each: both move at high speed, both require a deft touch under pressure and both depend on creativity to be successful. One thing is certain, whether it’s in business or hockey, you’ll be thrilled to have her on your team.

While Ryan is the newest guy around IDG, he certainly isn’t new to the industry. Having worked over 13 years in this industry, Ryan’s vast experience is beneficial to IDG. Ryan has touched every aspect of a project from initial client contact through project completion. Ryan obtained a Masters Degree in Architecture and Civil Engineering / Construction Management while attending the University of Illinois. There is another side of Ryan too. He’s an avid sports fan, including all of Chicago’s teams (except the Sox!) and he can always be seen rooting for the Fighting Illini. Ryan also enjoys golfing, tennis, photography, and traveling.
