Dave Holthaus is a seasoned quality assurance and nondestructive examination expert whose career spans more than five decades across some of the most technically demanding industries in the world. Known for his disciplined approach to quality systems and his commitment to technical excellence, Dave has built a reputation as a trusted advisor to organizations operating in the oil and gas, petrochemical, nuclear, and power generation sectors. His mission has consistently centered on helping organizations improve reliability, avoid costly mistakes, and elevate operational standards through thoughtful leadership and deep subject-matter expertise.
Dave’s professional journey began with his service in the United States Air Force, where he worked as an aircraft inspector and maintenance controller. During this early stage of his career, he developed a strong foundation in inspection protocols, mechanical systems, and disciplined operational procedures. This experience instilled in him an appreciation for precision and accountability—qualities that would later define his professional approach in the highly regulated fields of engineering inspection and quality assurance.
Following his military service, Dave continued his technical training at the Spartan School of Aeronautics, where he studied nondestructive testing, aircraft maintenance, and electronics. This education introduced him to the scientific and engineering principles that would shape the rest of his career. As industries increasingly relied on advanced inspection techniques to maintain safety and reliability, Dave found himself at the forefront of a field that was becoming essential to modern infrastructure and energy production.
Early in his civilian career, Dave performed hands-on nondestructive testing examinations, including ultrasonic, radiographic, magnetic particle, penetrant, and visual inspections. Working in the field allowed him to gain a practical understanding of how inspection technologies function in real-world environments. Over time, he transitioned from performing inspections to designing and overseeing quality programs, guiding organizations through complex compliance standards and helping teams improve their inspection practices.
Dave’s career trajectory eventually brought him to leadership and consulting roles with globally recognized organizations such as General Electric, Pacific Gas & Electric, Electric Power Research Institute, Suncor Energy, and several major petrochemical and energy companies. In these positions, he was responsible for evaluating inspection programs, conducting audits, and ensuring adherence to critical codes and regulatory standards including ASME and API requirements. His ability to identify systemic issues and implement corrective strategies has saved organizations significant time, cost, and operational risk.
One of Dave’s most influential areas of work has been in the development and evaluation of ultrasonic testing procedures used in pressure vessels, piping systems, and power plant components. Through decades of technical work and field observation, he recognized that many inspection failures stem from inadequate procedures or poorly trained personnel rather than from the technologies themselves. As a result, he dedicated much of his later career to improving training standards and refining inspection methodologies that lead to more reliable results.
Dave also co-founded Comprehensive Procedure Reviews, LLC (CPR), a consulting organization dedicated to reviewing and validating nondestructive examination and welding procedures. Through CPR, he and his colleagues developed systematic review methods designed to ensure that inspection procedures truly meet industry code requirements before they are implemented in the field. By focusing on procedural integrity and training quality, Dave has helped organizations reduce operational risks and prevent costly failures in critical equipment.
Throughout his career, Dave has also served as an educator, presenter, and thought leader within the inspection and quality assurance community. He has authored technical articles and case studies, including work published in Inspectioneering Journal, where he explored how inadequate ultrasonic testing practices can lead to significant operational costs. His writing and presentations are valued for translating complex technical concepts into clear lessons that engineers, inspectors, and corporate leaders can understand and apply.
In addition to his technical achievements, Dave has demonstrated strong entrepreneurial leadership. Through Holthaus Enterprises, Inc., he has spent decades providing consulting expertise, program development, and inspection oversight services to clients nationwide. His consulting work has supported everything from nuclear reactor vessel fabrication inspections to petrochemical plant quality programs, reflecting the breadth of industries that rely on his experience.
Despite his extensive technical credentials, Dave views mentorship and knowledge sharing as the most meaningful aspects of his career. With more than fifty years of professional experience, he is passionate about guiding the next generation of engineers, inspectors, and industry leaders. He believes that strong quality systems are built not only on technical knowledge but also on thoughtful leadership, ethical responsibility, and a willingness to learn from past mistakes.
Dave’s decision to pursue board and advisory roles reflects his desire to continue contributing to industries that have shaped his career. By working alongside executive teams, he aims to help organizations strengthen their operational frameworks, improve strategic oversight, and reinforce cultures of safety and quality. His board-level value lies in his ability to connect technical operations with strategic leadership decisions—ensuring that quality, compliance, and efficiency remain central to long-term success.
Outside of his professional endeavors, Dave enjoys woodworking and golfing, activities that reflect his appreciation for craftsmanship, patience, and focus. These interests mirror the qualities that have defined his career: precision, steady improvement, and dedication to excellence. Whether working in a boardroom, a fabrication facility, or a consulting engagement, Dave Holthaus continues to apply the same guiding principle that has shaped his life’s work—ensuring that quality is never an afterthought but a foundation for success.
