Our Team


Jonas Carnemark

Owner + founder


In 1987, Jonas Carnemark founded a company to realize his creative goal: to bring home remodeling dreams to life—with both beauty and purpose. Since then, he has grown a 20-person design + build firm where devotion to the clean lines of modern design flows easily alongside attention to comfort. It’s here that form and function, and service and integrity, co-exist naturally.

Kate Wilson



Designer Kate Wilson discovered her affection for kitchen design while helping her parents plan out their own. An Interior Design graduate of Auburn University, she also has closet design training and regularly updates her product knowledge in everything from fixtures to countertops and lighting to pro-grade appliances from Sub-Zero, Wolf, and Miele.

Christina Porcelli

Accounting administrator


You might say Christina Porcelli has twin talents. With 20 years of experience, the seasoned accounting pro can size up just about any P&L in a snap. But when her nose isn’t in the numbers, she’s a real people person—ready with support and a smile for customers and co-workers alike. Right brain, left brain, Christina excels in both hemispheres. Her customer service skills fit right in to the CARNEMARK culture.
