OUR STORY

HRGA was established to deliver top-tier architectural services to a wide range of clients across both the public and private sectors in Northern California and the Western Region. Our mission is to help clients achieve lasting project value through innovative and cost-effective solutions. We attribute our success to strong communication, creative problem-solving, collaboration, and a proactive approach to service.

 

We embrace cutting-edge technologies that enhance coordination and communication among all project participants. As dedicated professionals, we remain deeply involved in every project from start to finish, ensuring that each one meets its goals and objectives.

Founded in 2009, HRGA thrives under the leadership of Roland Ketelsen and Young Kim, who continue the legacy established by EHRA's founders, Richard Harper, Ron Reta, and Lou Viani, whose work spans more than 35 years.
