Working with Christina of SB Interior Design, LLC was an efficient and detail-oriented experience. It was a pleasure seeing her design come to life and I look forward to working with her again.

Brent, Contractor

Christina was very thorough and listened to my ideas and thoughts and then added her own suggestions to help me with my kitchen/dining room renovation design. I really enjoyed all her insight, experience, and I would highly recommend her to friends and family.
