Alyson Meucci


Alyson Meucci was born in Washington and raised in California. She always knew she wanted to be a designer and started shaping her skills at a young age by designing homes on computer programs for hours at a time. Alyson pursued a BFA in Interior Architecture at CSU Chico and has LEED experience. During her time at CSU Chico, Design SI principal Rouben Mouhiddin took notice of Alyson’s work in an architecture course called “creative thinking” which he considers a litmus test for student’s future success and asked her to join the Design SI staff. She has grown from a young intern to a full time designer and project manager. Her primary responsibility is to work closely with clients helping them with all aspects of projects, which range from predesign to selecting and specifying finishes, fittings, furnishings and accessories to construction management. She prides herself in the details of a project and getting to know her clients well enough to know exactly what they are looking for.
