"I worked with Jamie on a complex AB-2533 project in Marin, and he absolutely delivered. He created fully stamped plans that met every Marin County Fire Department requirement, stayed on scope and on budget, and most importantly guided me through an unusually challenging permitting process. Jamie is professional, reliable, extremely knowledgeable about Marin’s codes, and communicates clearly at every step. If you want an architect who can navigate the county, produce high-quality plans, and actually get your project over the finish line, Jamie is the one. Highly recommended."
