Principal, Open Practice Leader

As a founding principal at TLCD, Don’s 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. Having travelled extensively from a young age, Don is heavily influenced by international architecture, which brings subtle undertones to his work that strives for a high level of design. He can often be found with a fat pen in his hand as he delves into project conceptualization.

With an early focus on education projects, Don has continued to develop the diversification of the firm, which has taken TLCD into new markets – particularly commercial and mixed-use projects. He instills a belief that well-conceived architecture should be thoughtful while embracing new ideas and technologies.

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