Meet The Team
Brian Larson
Founder & Chief Executive Officer
Precision Leak Testing Consultants
Brian Larson is the Chief Executive Officer of Precision Leak Testing Consultants. He leads the company’s strategic direction, program development, and technical integration, with a focus on advancing leak testing as a critical discipline in safety, quality assurance, and mission success across high-consequence industries.
Brian is an ASNT Level III in Leak Testing with extensive experience in the development and execution of leak testing programs within nuclear, aerospace, and complex manufacturing environments. His work spans both field operations and program leadership, where he has been responsible for designing test strategies, standardizing methodologies, and ensuring that leak testing is applied as a structured and defensible component of system verification.
Over the course of his career, Brian has supported a wide range of challenging testing scenarios, often in conditions where environmental variability, system complexity, and schedule pressure must be carefully managed without compromising data integrity. His experience has led to a practical, solutions-driven approach that emphasizes not only technical accuracy, but also repeatability, traceability, and alignment with applicable codes and standards.
Through Precision Leak Testing Consultants, Brian is focused on addressing a persistent gap in industry: the need for fully integrated leak testing programs that combine technical rigor, qualified personnel development, and real-world execution. He believes that leak testing is frequently underutilized when treated as a downstream activity, and instead advocates for its early integration as a means of reducing risk and improving overall system reliability.
Brian’s work is grounded in a commitment to technical integrity and long-term performance. He is actively involved in developing training programs and methodologies aimed at strengthening the next generation of leak testing professionals, while helping organizations build internal capability that extends beyond individual projects.
