Design Principal

Don’s role as Design Principal brings a much-valued level of experience and design oversight to project teams of all types in the office. A founding principal at TLCD, his resume boasts an impressive list of award-winning projects. It’s no wonder, having followed in the footsteps of his father, an architect with an infectious enthusiasm for the profession. A native of Santa Rosa, Don clearly recalls the establishment of his father’s firm, Thomas M. Tomasi Architect in 1965 – a place where Don and his brother (also an architect) spent their early years learning the profession.

Although Don is actively involved in the leadership of the firm, his role as Design Principal allows him to do what he loves best – creative architecture which brings to life a client’s vision for a project. He is known for his ability to work nimbly with multiple project teams, both in-house and in the community. Whether it be a campus masterplan, a new retail bank building or a vehicle maintenance complex, Don’s boundless energy and enthusiasm are inspiring. Designers and project managers alike appreciate his ability to see “the forest for the trees” and find solutions that support over-arching project goals.

Having travelled extensively from a young age, Don is heavily influenced by international architecture, which brings subtle undertones to his work that strives for thoughtful and well-conceived design. He can often be found with a fat pen in his hand as he delves into project conceptualization.

I enjoy a lot of outdoor activities but my claim to fame is having hiked the John Muir Trail twice!
