The Board of Directors of MISTRAS Group, Inc. is deeply saddened to announce the passing of Dr. Sotirios J. Vahaviolos, the company’s Founder, Chairman Emeritus, and Board Director.
A visionary leader and pioneer in the field of non-destructive testing (NDT) and acoustic emission (AE), Dr. Vahaviolos founded MISTRAS (originally Physical Acoustics Corporation) and dedicated over four decades to building it into a global leader in testing, inspection, and asset protection solutions. His expertise, leadership, and commitment to excellence were instrumental in shaping the company’s strategic direction and fostering a culture of innovation that remains at the core of MISTRAS today.
Dr. Vahaviolos and the Board of Directors took careful measures over the years to ensure a seamless transition and continuity of leadership. MISTRAS will continue to operate as planned, with no changes to the company’s management or strategic direction.
Prior to founding MISTRAS, Dr. Vahaviolos was a scientist and manager at AT&T Bell Laboratories, where he honed his expertise in electrical engineering and advanced NDT technologies. A distinguished academic, he earned a B.S. in Electrical Engineering (graduating first in his class) from Fairleigh Dickinson University, followed by an M.S., M.Phil., and Ph.D. in Electrical Engineering from Columbia University School of Engineering.
