Thomas D. Elfmont - CEO, Founder

Job Titles:
  • CEO
  • Founder
Thomas D. Elfmont, founder and CEO of TDA, has been a leader in the security and investigative industry for over twenty-five years. Utilizing extensive experience gained through a thirty year career leading the Los Angeles Police Department, Tom formed TDA to meet the security and investigative needs of the private sector in Los Angeles. Soon after its founding in 1994, Tom quickly recognized that the needs of TDA's client were increasingly global in nature and that these challenges could only be met by having personnel on the ground overseas. Subsequently, Tom built a network of global alliances to allow TDA to effectively meet these needs. TDA entered into several successful partnerships which ultimately led to the opening of TDA partner offices in several countries around the world. Since its founding, TDA has grown from a firm working primarily with a Los Angeles based clientele to a security and investigative firm that is truly global in outlook, clientele, and capacities.
