Building Lasting Relationships Through Architecture

Pacific Cornerstone Architects Inc. (PCA) is a full-service design firm offering integrated design services to our clients since 1994. PCA offers planning, architecture, interior design, and sustainable design services to a diverse base of clients in all areas of architecture.


PCA is regarded for our strength in design, development, entitlement, and the approval process. We strive to develop creative solutions that simultaneously consider program, market, and codes, with context to provide sensitive and environmentally conscious designs. Through a collaborative process with our clients, consultants, and governing bodies, we synthesize the objectives, opportunities, and challenges to develop a holistic design. Our goal is to create innovative design solutions that exceed our client’s expectations and are assets to the community. 


At PCA, we believe that our team should strive to develop on a personal and professional level every day.  Our principal’s extensive experience in the field provides a strong foundation to continued growth throughout the studio. By mentoring, we collectively raise the level of the studio through open communication and team collaboration. With an average tenure of over twelve years for employees at PCA, new employees are paired with mentors, and existing employees are encouraged to find a mentor as well in the office.


At PCA, we seek to create events that bring people together. We believe that creating an engaged company culture strengthens the lives of our employees and the work they do. Through events to find commonalities in interests and views, we help foster an environment of collaboration inside and outside the studio. Whether through an informal happy hour, an educational and community volunteering event, or an organized activity to take in the San Diego lifestyle, PCA employees enjoy spending time together outside of the office.


We encourage community involvement in our studio, so we are always looking for local opportunities and cause to partner with and further. At PCA, we want to support our families, employees, AND the community, so we embrace the occasion to better the world. Whether it be through a local beach clean up or heading down to Mexico to take part in a Habitat for Humanity build, we want to make a positive impact in our community!
