As an executive and business coach, and an international leadership, team engagement and culture speaker, Jeff is known for his unique perspectives, for challenging traditional thinking, and for delivering tangible shifts for leaders to grow their people, build their businesses and enhance their relationships. Jeff also worked extensively with business owners and their teams to help them achieve their highest levels of performance and business growth.

Jeff’s work included working with law firms and their leaders in four core areas: ensuring your firm’s future with succession planning and future leader development; building business development cultures and accelerating revenue growth; engaging, empowering and entrusting your team; and navigating the practice of law with less stress and more peace. Jeff’s now bringing this experience and skillset to Core X Legal’s impact and growth mission.

Jeff’s the author of five leadership and personal development books including Think Again! Innovative Approaches to the Business of Law; Unmask: Let Go of Who You’re “Supposed” to Be & Unleash Your True Leader; Arrows of Truth: Simple Shifts for Personal Transformation; Just One Step: Walking Backwards to the Present on the Camino Trail; and his recently launched Snow Globe Leadership: Shaken, Not Settled (2021).
