About me
Executive Coach - Farnham
I'm Gary Armstrong and I founded Pinnacle Coaching and Development to help teams, leaders and individuals make meaningful changes to deliver sustainable high performance.
I develop senior teams through facilitation and coaching, deliver leadership development programmes and provide 1:1 executive coaching.
I bring 25+ years experience as a strategic leader navigating high-stakes global operations across the life sciences, professional services and major projects sectors.
As an experienced and accredited 1:1 coach and team coach, I focus on high-impact, 'in-the-room' development. I swap abstract theory for evidence-based approaches that deliver immediate, measurable results.
My 1:1 and team clients enjoy my warm style but work hard in each session to achieve real change and make progress towards their goals.
Typical coaching areas for me are:
• Supporting team development: initiation, realignment and sustainment
• Developing teams immersed in major projects
• Development of leadership confidence: vision, style and presence
• Supporting leaders transitioning into senior level roles
• Coaching leaders of major transformation and other high-stakes environments
• Supporting major mid-life career decisions
I balance my work with global corporate clients by advancing the capabilities of leaders and teams within SMEs. My client sectors include pharmaceuticals, healthcare, law, finance, consulting, consumer technology and motorsport.
I am also a tutor on the Oxford Saïd Business School’s Healthcare Leadership Programme.
Education & Qualifications:
• MA in Economics, University of Cambridge.
• Accredited Coach, International Coaching Federation (ICF).
• Specialist Qualifications in Adult Learning, Psychology Coaching, and Team Coaching.
Outside of work, I’m a keen runner and cyclist and I firmly believe finding joy on the road matters as much as winning the race.

Working with Gary has been highly beneficial for me. He is an experienced and deeply professional coach with outstanding integrity. His questions land powerfully and continue to resonate long after the sessions themselves. Gary creates space when it is needed and, at just the right moments, reflects back what I have said in a way that brings clarity and insight. He is also very transparent in indicating when he shifts from a coaching stance to offering comments or advice. On top he is always eager to recommend an interesting book to enable further learning. I can wholeheartedly recommend Gary to anyone who wants to better understand their own motives and behaviors, act on that understanding, and grow as a leader. Finance Executive.

Gary is a wise, empathetic, and deeply professional coach who has helped me immensely in my leadership journey. I am regularly amazed at how Gary has helped me arrive at conclusions or realisations I wouldn’t have thought possible but have proved to be very valuable in improving my leadership skills and self-confidence.
