Brian R O Callaghan

Throughout my career, I have been fortunate to have a diverse range of real-world experiences that have greatly influenced my creative work. As a firefighter, EMT, police detective, police academy instructor, and corporate security professional, I have encountered a wide variety of situations that have deeply impacted my perspective and provided rich material for the storylines in my books. Each experience has contributed to the authenticity and depth of my narratives, infusing them with a profound sense of realism.
