Our People

ADS understands that each client has its own unique organizational structure and culture, operating and maintenance characteristics, resources, and program priorities that must be considered and understood so that safety and security program performance can be objectively assessed. Only then can truly important safety and security program issues be targeted for more in-depth analysis, and only then can truly meaningful recommendations be developed and effectively implemented to improve performance. 

This understanding comes from the practical, first hand experience of our highly skilled and degreed engineering staff, which includes certified Safety Management System (SMS) practitioners and system safety and security experts, seasoned accident investigators, practiced auditors and inspectors, industry leading trainers, and experienced engineers in the fields of mechanical, electrical, systems, industrial, safety, aviation, and fire protection engineering.
