WAO ISO Certification Extension 1000 x 600

Poulsbo, WA, and Winters, CA, Sites Achieve ISO Certification

Posted by Barb Viner-Fronk on January 13, 2026

We are thrilled to announce that Brennan's Poulsbo, WA, and Winters, CA, sites have officially earned certification to ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety) Systems as part of our most recent scope extension.

This is an outstanding achievement that not only highlights our technical expertise but also demonstrates our continued commitment to quality, environmental stewardship, and the health and safety of our employees, clients, and stakeholders.

A True Team Effort

The Poulsbo and Winters crews rolled up their sleeves, embraced training, corrected gaps in processes and documentation, and tackled each challenge head-on. This success also required close coordination with corporate headquarters to align procedures, update documentation, support audit preparation, and ensure our quality, environmental, and safety systems were consistent across all locations.

Our close collaboration ensures that, regardless of our location, our clients receive the same consistent, high-quality service. Along the way, employees built new skills, strengthened their knowledge, and developed a shared sense of pride in the work they do every day. By working together, we created a unified, integrated approach that reflects Brennan's commitment to continual improvement and organizational excellence.
