Our Mission

We focus our endeavors toward finding balance in social, financial and environmental achievements.

Started in 2006 Convergence Architecture specializes in planning, architecture, and interior design services for commercial, residential, healthcare, and public clients. The firm’s portfolio of work is diverse in scope and building type, but our design approach is always the same: strong team communication between architect, client, and consultants to converge on a design that integrates budget, program, and aesthetic goals.

Convergence Architecture is an Oregon certified Woman Owned Business (WBE), Emerging Small Business (ESB) and Disadvantaged Business Enterprise (DBE). #7559

We have architects licensed in Oregon, Washington, California, Idaho, Indiana, North Dakota and Wisconsin as well as LEED AP BD+C.

With three experienced principals – each with complementary strengths – as well as a diverse, responsive staff, we draw on each other’s expertise to ensure each phase of a project goes smoothly and successfully.

Convergence Architecture contributes to your projects with:

  • Innovative thinking

  • Opportunity-based solutions

  • Proactive communication

  • Respectful interactions

  • Collaborative perspectives

  • Experience-based solutions

Working with Convergence Architecture to transform the playground at James John Elementary was a great experience. Joseph gracefully guided our vision for the space over the course of two years, and connected us to the right specialists and solid contractors to help accomplish our goals. The project wouldn’t have been a success without them. Thanks from the Crew at Depave!

When we purchased our home with a detached Accessory Dwelling Unit, we had no idea the lengths we would have to go to legalize the building and make it safe for my mom to retire in. Barb Anderson and the rest of the team at Convergence provided the expertise, guidance, insights, and ideas that got us over the panic of having to rebuild nearly everything. They helped us throughout the construction as well by answering questions and providing guidance when we ran into roadblocks. The project is nearly complete now, and the structure is fully legal per the city’s code enforcement division, and we couldn’t be happier with how it all came together. The second home is beautiful.

I was privileged to work with Joe Purkey of Convergence Architecture on quite a few of his projects, and I was truly impressed with his professionalism, thoughtful designs, and knowledge of construction. I would recommend him without reservation!
