As a well-established Architecture and Interior Design firm, Williams + Paddon celebrated 40 years in the industry in 2022. That same year W+P announced a merger with 19six Architects, one of the oldest architectural firms in California. 19six specializes in Education and Healthcare markets, both complementary to the markets W+P currently serves. 19six is headquartered in in San Luis Obispo, CA, and now has eight offices across the state: San Luis Obispo, Santa Barbara, Corona, San Francisco, Santa Cruz, San Jose, Sacramento, and Roseville. We are joining one team with over 100 employees who all share a passion for design excellence. Joining 19six has expanded our reach and add a broader network of talented staff to work with us as we grow together. Equally important, we share similar cultures, values, and vision. As a result of this deep network and aligned culture, W+P staff will have new opportunities for career growth and new resources for learning and development.

Our principals, Jack Paddon, Naaz Alikhan, Terry Green, and Greg Tonello are excited to join forces with 19six Architects; the company brings stability and resources which will enhance our work. To everyone we work with, fundamentally, it will be “business as usual.” We will continue our presence in this region with our two offices (Roseville and Midtown Sacramento). We will maintain our current client services, and personnel will not change. We’re excited to continue our active membership in the communities we helped build and grow with over the last forty years.

We look forward to this new chapter and to continuing our legacy of excellence in design services for our many clients as 19six Architects.
