Led by Experience.
Driven by Purpose.
Sam Kinsey-Briggs MBE MA
I’m a life coach, mentor, and storyteller with 27 years of leadership experience in the UK Armed Forces, having started as a Private Soldier and retired as a Royal Navy Captain. My military journey taught me how to lead under pressure, adapt to uncertainty, stay grounded, and unite people around a shared purpose. These experiences shape the way I coach today. I work with people who are done waiting, those at a crossroads, ready to break through what’s holding them back. If you’re navigating change, stuck in transition, or determined to lead with conviction, I offer more than support...I offer momentum. I’ll ask the questions you’ve avoided, bring order to the chaos, and guide you to align your values with bold, meaningful action. When you’re ready to move forward, I’m ready to help you lead the way.
Lloyd Allen
MBA
I’m a life coach with a background in security, defence, and leading in high-pressure environments. Throughout my career, I’ve helped individuals and organisations adapt, grow, and overcome real-world challenges using straightforward strategies that actually work. My coaching doesn’t come from textbooks; it comes from real-life experience. I’ve led in high-stakes environments where clarity, confidence, and decisive action aren’t optional; they’re non-negotiable. If you’re facing change, rebuilding your confidence, or standing at the edge of something bigger, I’ll help you cut through the noise and find the next step with purpose. You don’t need more information; you need someone who sees your potential and knows how to help you act on it.

Client Success Stories
Real transformations from real people. See how our coaching has helped individuals achieve their goals and create lasting positive change in their lives.
ACSIS helps you challenge the way you’ve been thinking, set clear goals, and approach challenges differently. With Sam’s support, I was able to break old patterns, gain new perspectives, and start making real progress towards the goals I had set for myself.
Working with ACSIS helped me break big goals into smaller, more manageable steps that fit my demanding career. Each session leaves me with clear objectives to work on, helping me stay on track and maintain balance between work and personal life.
Sam brings a calm, confident approach shaped by years of military leadership and real-world experience. While grounded in military excellence, the coaching is never rigid. It’s forward-focused, helping me plan ahead, create real change, and become the person I want to be.
After leaving the police force… I found myself at a crossroads—ready to re-enter the workforce but uncertain about how to move forward. Sam’s approach was nothing short of transformative… I now approach interviews with confidence and a clear understanding of how my values align with those of potential employers.
I found the silent coaching session really helpful. It unearthed a significant issue I had been ignoring and helped me think about some practical steps to take to start addressing it. Being asked questions I would never think to ask myself was a catalyst for productive self reflection and change.
The silent coaching session was such a gentle but powerful experience.
I finally made the decision to take the leap and retire. If it wasn’t for Sam’s support, I know I’d still be stuck going back and forth.
