RRM’s mission is Creating Environments People Enjoy®. Our work and our culture embody sustainability, collaboration, innovation and respect. Our firm’s unique structure also serves as a foundation for the energy and inspiration that drive our team: we bring over 170 architects, engineers, landscape architects, planners, and surveyors together under one roof to take on projects throughout California from idea through implementation. The result is genuine, cutting-edge, and timeless designs which aim to leave a lasting and positive imprint on those who experience them.


The RRM ESOP is a Trust created for the benefit of the employee members. The Plan is approved by the IRS and is a form of retirement plan, regulated much like a 401K plan by strict IRS and Department of Labor rules and procedures. As an ESOP (employee stock ownership plan) corporation, all RRM staff have an ownership interest in the company. This is a direct reflection of our culture, one that is a supportive team. We are all striving to grow this company forward so that we can continue to create projects that promote sustainability and social good, giving back to our communities we live and work in and supporting staff so they can support their families. We are a team working together towards common goals.

THe 45+ year history of RRM Design Group


THe beginning of it all

In 1974, Priest, Richmond, Wolff, and Rossi (PRWR) was founded by three Architecture students and their professor. November 18th, 1974 Rossi was appointed as President.


RRM Gets its name

In 1981, Vic Montgomery succeeded Rossi as President, and the company was re-named Richmond Rossi Montgomery (RRM). RRM added Planning services in 1983.


Creating Environments People Enjoy

In 1985, RRM changed its name to RRM Design Group, and created its Mission Statement: Creating Environments People Enjoy®. Landscape Architecture services were added in 1988.


RRM adds more services 

In 1995 RRM added Civil Engineering and Survey services when they acquired Tierra Engineering. In 1996 the Modesto office was moved to Oakdale.


RRM adds more offices

To accommodate expanding growth, additional branch offices were opened in Healdsburg to cover Northern California and San Juan Capistrano to cover Southern California.


RRM grows in the central coast

In 2011 RRM acquired the firm LGA and in 2013, RRM acquired the firm PGA. These firms grew our architecture practice with an increased focus on affordable and specialty housing; we also grew to Santa Barbara though the PGA acquisition.
