Brandon began his career as an in-house ammonia refrigeration system operator and later transitioned into a nationwide service technician role supporting Ammonia, Freon, and CO₂refrigeration systems. His hands-on operational experience informs his current work in compliance engineering, mechanical integrity program development, and regulatory alignment for covered processes under EPA RMP, CalARP, and OSHA PSM frameworks.

He is a RETA Certified Industrial Refrigeration Operator (CIRO), RETA Authorized Instructor, and holds an ASTI Instructor Certification, with advanced training through the University of Wisconsin–Madison Industrial Refrigeration Consortium in the Principles and Practices of Mechanical Integrity for Industrial Refrigeration Systems. As a credentialed educator, Brandon develops and delivers regulator-focused training for industrial facilities, local RETA chapters, and regulatory agencies throughout California, Oregon, Washington, Idaho, Utah, Arizona, Nevada, and Canada.

Brandon serves on the RETA Educational Committee and IIAR Committees on Education and Process Safety Management, collaborating with industry and regulatory stakeholders to support consistent interpretation and application of PSM and RMP requirements. In 2024, he was nominated and accepted to the Board of Directors for the Ammonia Safety and Training Institute (ASTI), where he supports hazardous materials and emergency responder training programs relevant to ammonia release prevention and response planning.

His professional expertise includes ammonia refrigeration, compliance engineering, mechanical integrity programs, management of change, operating procedures, training, incident investigation support, and the development and implementation of Process Safety Management (PSM)and Risk Management Programs (RMP) for regulated ammonia refrigeration systems

Eileen Woodbury Mosqueda is the Corporate EHS Technical Manager for Process Safety Management (PSM) and Risk Management Plan (RMP) programs at E.&J. Gallo Winery. With more than two decades of experience in process safety, regulatory compliance, and ammonia refrigeration management, she brings a deep commitment to safety leadership and continuous improvement within high‑hazard industries.

Eileen began her career in 2002 with the Monterey County CUPA, working within the California Accidental Release Prevention (CalARP) program. During her tenure, she also served as a responder with the Operational Area Hazardous Materials Team. She also developed and implemented best practices for ammonia wastewater management. This early regulatory and emergency response work shaped her belief that active outreach and education are essential—not only for achieving baseline compliance but also for fostering long-term operational excellence. She carried this philosophy forward as she transitioned into industry, where she has shared her expertise as a speaker at numerous local and statewide conferences, helping educate and advance the refrigeration community.

In her current role at Gallo, Eileen continues to champion strong regulatory alignment while cultivating a culture where process safety best practices evolve and strengthen over time. Outside of work, she enjoys spending time with her husband and children as they explore their new home in Modesto and the surrounding Central Valley of California.
