Dr Peter Gruenewald, MD

Dr Peter Gruenewald is a physician and applied leadership practitioner specialising in state regulation, sleep, and performance under pressure. He bridges clinical medicine, behavioural science, and executive leadership to create practical, trainable methods that help leaders remain clear, composed, and effective in high-stakes environments.

He is a Clinical Specialist in Behavioural Sleep Medicine and Integrated General Medicine at University College Hospital London (RLHIM) and a part-time private GP in London, following 24 years as an NHS GP.

His work addresses the operational realities of leadership in both public and private sectors — including decision-making under stress, cognitive clarity, recovery, and sustainable performance — making it relevant for senior executives, major-project leaders, entrepreneurs, and MBA students preparing for complex, high-responsibility roles.

Dr Gruenewald contributes to leadership development programmes with organisations including the UK Major Project Leadership Academy (MPLA), Orchestrating Major Projects, the Institute for Public Administration (Ireland), and the United Nations System Staff College. He served as an Associate Fellow at Saïd Business School, University of Oxford (2010–2024), and continues to support executive leadership programmes across sectors.

Through his Adaptive Resilience programme, he has trained leaders from corporate, public, and professional organisations, including the NHS, HM Revenue & Customs (HMRC), HM Treasury, and senior leadership teams in large-scale public and private enterprises.

He is the creator of three structured, protocol-based training systems designed for leaders:

• Executive State Training™ (EST) — rapid, repeatable state control for real-world performance
• Leadership Presence Path™ (LPP) — depth, clarity, and composure for senior leadership
• Restorative State Training™ (RST) — recovery and resilience for sustained effectiveness

He is the author of Self-Leadership: Realize your True Potential (2023) and The Quiet Heart: Putting Stress in its Place(2007), and has published widely on wellbeing, leadership, and performance.
