Giselle Timmerman has 17+ years of experience partnering with clients, from founders to Fortune 500 teams, to build stronger leadership and team cultures for greater engagement and competitive performance. She was one of the first 30 people in the world to study with Martin Seligman, the founder of positive psychology, and has applied the science since 2005 to improve people’s working lives.
With Blue Garnet, Giselle has partnered with many clients on strategic business planning, organizational assessment, social enterprise development, financial sustainability, marketing, and leadership and team development. She feels most in her element when posing challenging questions that invite candor and ah-ha moments critical to effective organizational change. In her current role as an Affiliate, Giselle supports client work in targeted capacities, largely focusing on strategic social innovation, change management, and leadership coaching. She wears another hat as Advisor for the firm’s Shared Leadership practice, which allows her to geek out on organizational behavior research and develop insights that apply to leadership within the social sector.
Giselle holds a Master’s degree in Applied Positive Psychology with a concentration in Organizational Leadership from the University of Pennsylvania, and graduated Magna Cum Laude from New York University with Bachelor’s degrees in Sociology and Psychology. Driven by her curiosity for new cultures and extreme adaptability, Giselle is currently based out of Barcelona, Spain, where she lives with her husband and two girls.
