About Jackie Cook

Momentum Group supports leaders navigating change by helping them gain clarity, build confidence, and take intentional action.After more than 20 years partnering with senior leaders and teams during periods of growth, change, and transformation, I created Momentum Group to support mid-career leaders and organizations stepping into their next level, whether that’s growth, transition, or reinvention.My work sits at the intersection of organizational effectiveness, leadership development, and operational discipline, grounded in the belief that sustainable results are built when people are clear, capable, and aligned.Throughout my career, I have led enterprise initiatives across operations, customer experience, product, and organizational transformation. I help organizations navigate complexity by aligning strategy, structure, and leadership behaviors to create momentum and trust. My strength lies in bringing clarity to complex environments while supporting leaders as they scale teams, systems, and impact.My approach blends business rigor with human-centered leadership. I draw on experience in organizational leadership, change management, and performance enablement, supported by formal training in psychology and Organizational Leadership from Penn State, MIT’s Mastering Design Thinking, and Lean Six Sigma. Whether guiding leaders through transformation, strengthening leadership systems, or enabling teams to perform at their best, my focus is on helping people move forward with clarity and confidence.I believe success is built where leaders feel supported, teams feel aligned, and organizations invest in both performance and people. If you are navigating change and looking for clarity on what’s next, I would welcome the opportunity to connect.
