Biography
In the 1990's, decorated officer Roger St. John-Ffolkes left the British Army and became a strategic consultant for a UK-based private military contractor (PMC). What he learned there encouraged him to strike out on his own. Calling in favors from contacts gleaned from years in the Army, St. John-Ffolkes set up Belltower UK, the precursor to the Belltower Group PLC. His personal ethos informed everything about the company's operations and corporate policy, and Belltower became known for its refusal to engage in any contracts of an "ethically challenged" nature.

In 2024, Roger St. John-Ffolkes officially stepped down as CEO of Belltower Associates, giving joint control of the company to his sons Luther and Andrew. In reality, he served only as a figurehead in this post for the last decade.
