Okay, let’s tackle this. So Karen Tenzer has 29 years of experience as an interior designer, which is impressive. Her skills in Sketching, Indesign, Ff&E, Architectural Design, Interior Design, Furniture, Space Planning, and Design Research are in demand. Location is Santa Barbara, California, which is a desirable location for design professionals. Considering her experience and skills, I would estimate her hourly rate to be around $125, which is slightly below the national average for interior designers in the US. This is because she is based in a smaller market, and her experience is more focused on design rather than high-end architecture. Some interior designers in larger cities or with more extensive experience can charge upwards of $200-$300 per hour. However, Karen's 29 years of experience and her focus on design rather than architecture suggest a more modest rate.
