HD Group-Global was founded in London in 2016 by Dennie, a travel risk management specialist. He has been working for nearly a decade, providing private security to several high-profile families across the globe. His low-profile professional approach and his ambitions to implement high-end medical cover within the security services have resonated with UHNW families and at-risk individuals. As a result, demand has risen, making HD Group-Global pioneers in their field.

As HD Group-Global developed, Dennie spent the following years working to ensure that the company was always at the forefront of the risk mitigation sector. Realising a fundamental gap in the safety and well-being of clients within the security sector, HD Group-Global set out to integrate highly skilled medical support into security services, ultimately pushing Dennie to employ an elite medical team alongside his expert security personnel.
