Effingham, IL – November 13, 2025 — The Effingham County Chamber welcomes Ivy + Birch Design Company as its newest member. Based in Effingham, Ivy + Birch Co. is a full-service interior design and contracting business known for transforming homes through thoughtful design, quality craftsmanship, and a down-to-earth, client-focused approach.
Ivy + Birch Co. is led by Owner & Designer Jennifer Jones, joined by Special Projects Designer Kate Mammoser and Designer/Project Specialist Shelby Hinterscher.

The Ivy + Birch team brings a refreshing mix of style and skill to the region. Jennifer’s eye for functional and beautiful spaces pairs seamlessly with Kate’s strong DIY and woodworking background—having redesigned nearly every room in her own home—and Shelby’s design insight and project support. Together, they offer everything from complete interior decoration and color consulting to statement walls, general contracting, e-design packages, and custom wood projects.
