Spectrum Design Group Team Meeting


We are a team of multidisciplinary designers who create beautiful, enduring environments that stand the test of time for every client. One of the best aspects of what we do is resolving the issues clients have with the areas in which they live, work, and relax.


our team

As a turnkey company, we are uniquely equipped to design, specify, and manage your project from concept to completion. Since 2009, we have dedicated ourselves to proving that hiring a design firm does not have to be stressful nor intimidating.


Clients contact SDG because of our portfolio. They choose to hire us because of our heart. Our standards are high for every aspect of a project from the quality of the design to the materials specified to the craftsmanship of our contractors and we combine that with a fun-loving, down-to-earth family atmosphere. 

We serve residential, corporate, and hospitality clients in Champaign-Urbana and throughout the Midwest.

Jeff Kaper

Owner & Principal

Jeff has been involved in the creative world for more than 20 years specializing in residential kitchens and baths as well as custom commercial casework. He will tell you the best part of his job is the amazing clients he has worked with through the years, many of them becoming close friends.  He holds a BA from Taylor University. Jeff and his wife, Sarah, have four children and two cats (translation: no hobbies). Jeff’s interests include running, great music, working in his yard, epicurean dates with his wife, and family adventures.

"Jeff listened to our ideas and worked diligently to create a beautiful yet practical kitchen that fit our style and complemented the rest of our home’s renovated interior."

Dawn Bane

Designer & Color Expert

Dawn has had a passion for all things art and design from a young age. She earned her BFA in interior design from Iowa State University then began her career in Chicago working in both the residential and commercial design markets. After falling in love with a farm boy from central Illinois, the two relocated to the C-U area. Dawn loves being a part of the SDG team and feels blessed to be able to do what she loves every day. When not designing, she and her husband spend time playing and exploring with their sons.

"It was evident from our initial consult that Dawn had a keen eye for design, texture, and color, but what also came through was her warm personality, professionalism, and attention to detail."

Cory Rodeheaver

Cory Rodeheaver

Designer & Director of Safety

Building his first treehouse at the age of eight, Cory has been interested in homes ever since. Many tents and treehouses later, Cory entered into the professional world of design working as a scenic designer in theater and a senior exhibit designer/art director in the museum and themed entertainment industry. Joining the SDG team has allowed Cory to channel his creative spirits back "home" for which he is thankful. Outside adventures and photography are interests of Cory's, as well as spending time with his wife and three children.

"Cory provided us with design ideas that matched our aesthetic and budget, worked quickly to make any requested adjustments, and suggested innovative solutions and ideas to improve the functionality and look of our house."

Kara Vanskike

Marketing Director & Office Manager

Growing up in a home built and maintained by her parents, Kara spent much of her time in home improvement stores where she collected samples for her own interior design firm. At eight or nine, she had quite the business. However, once she realized she lacked any real design ability, she gravitated toward opportunities to work with creative people. Kara is blessed with two boys and spends her free time adventuring with them. She is also active in the Down syndrome community as her youngest is rockin’ an extra chromosome.

Kara Vanskike

"Kara was so kind and reached out to me every day to see how I was doing. Granted, I owed thousands of dollars, but through it all, we became very close friends."
