About Us

Boston, Executive Coach

GTL Coaching & Consulting, Boston

GTL partners with C-Suite and senior executives, as well as their teams, to understand what makes them successful and what limits their effectiveness. We collaborate closely as leaders work through frank feedback, reflect on their impact, clarify what they want, and develop a roadmap for growth. We support them to challenge their own thinking and expand their repertoire, providing an active sounding board as they experiment, learn, develop, and perform in their roles. 

While primarily an individual consultancy, GTL contracts with other expert coaches and consultants for large-scale projects.

Further Background

Prior to GTL in her career as a management consultant, Ali co-developed strategic projects in Fortune 50 to mid-sized corporations in a range of industry sectors, helping senior teams design and implement business-specific and corporate-wide strategies. Before 'coaching' was a term used in organizations, she guided executives through challenging 360-degree feedback programs, facilitating difficult conversations with their teams and supporting them from conflict to productive action.

As a Research Associate at INSEAD, Ali conducted research into the predictive factors for success and failure in international mergers and acquisitions, and also into best practices in international human resource management, collaborating on two books and co-authoring several case studies for use in MBA and Executive Education programs.

While raising a family, Ali also spent a number of years as Board Member/Board Chair of a variety of non-profit, community, and education-related organizations. She was known community-wide for insightful leadership, influence without authority, building alliances, and getting the job done in situations with multiple concerned parties and high emotional stakes.

Today, Ali continues to devote significant pro-bono Board and Committee time to causes such as mental health, special education, and the mentoring and advancement of women in STEM careers.
