From conducting complex surveillance operations to locating missing persons, John’s work has consistently delivered results where others could not. His experience extends into some of the most challenging areas of investigation, including cases that uncovered critical evidence later turned over to homicide police agencies for resolution.
A recognized expert in covert operations, John has earned a reputation for precision, discretion, and results. His professional portfolio includes high-level protective assignments for corporate executives as well as operational planning and coordination for the protection of two U.S. Presidents. These assignments required not only investigative skill but also strategic foresight and absolute confidentiality.

His leadership at Agency M ensures that every case—whether personal, corporate, or legal—is handled with professionalism, discretion, and a relentless pursuit of results.
