Our History
Transformative architecture and trusted client relationships have been at the core of c|a from the start. The firm was established in 1992 based on the belief and trust of Torrance Memorial, a partnership that continues today. The team was built on a synergistic collaboration—the technical expertise and creative energy of Edward Caruana and Eileen Amano-Peterman.
For over 30 years, the firm has adapted and grown—acquiring new talent, adopting new technologies, implementing improved systems, and elevating the design of healthcare environments. The c|a team has remained in stride with the ever-evolving healthcare industry, balancing the technical intricacies of infrastructure and cutting-edge systems with refined aesthetics and human-centered details—creating meaningful architecture to impact and inspire wellness.
