A trusted resource for Northern California’s technology community
Since 1981, Gagner-Toomey Associates (GTA) has served as a trusted connection between world-class manufacturers and the engineers, designers, and technology companies shaping the future. Based in Northern California, we work closely with customers across a wide range of industries, providing access to technologies and the expertise needed to support informed design decisions. Over the past four decades, we’ve built our reputation on responsiveness, technical understanding, and a commitment to helping customers find the right fit for their unique requirements.
Built on relationships, not transactions
At GTA, we believe a successful business is built on strong relationships. Technology continues to evolve, but the value of trust, communication, and reliability remains constant.
Our approach is simple: listen first, understand the challenge, and connect customers with solutions that align with their goals. By taking the time to understand both the technical and business considerations behind a project, we become a valuable resource throughout the design and decision-making process.
Many of our customer and manufacturer relationships span decades, reflecting our commitment to long-term partnership and mutual success.
