About Us


Specializing in design for seniors, our purpose at Interiors by Marianne is to integrate comfort, functionality and safety with the aesthetics of enduring design.

“I would like to state that I have worked with Marianne Henderson on several past projects and have always found her design aesthetics and work ethic to be of the highest caliber. She goes out of her way to please her clientele and her trouble-shooting capabilities far surpassed my expectations. I have never experienced her quotes to be out of line and she is ideal for budget-minded skilled-nursing facilities. I will continue to utilize her talents and am happy to provide her with a strong reference.” – Terry Stewart Administrator, Crown Bay Nursing and Rehabilitation Alameda CA
