Isaac is an expert on the promotion of well-being in individuals, organizations, and communities. He has presented keynote addresses in 26 countries in four languages. His talks combine humor with science and practice.


The perfect kick-off to the 2019 World Happiness Summit was an uproariously funny and deeply meaningful keynote address by Dr. Isaac Prilleltensky called “Mattering is no laughing matter, or is it? This distinguished and dedicated scholar, professor and coach, delivered a compelling story with hilariously colorful examples from his own life about how feeling valued creates a sense of belonging, which contributes to one of the most essential factors for well-being and a happy life, which is the feeling that one matters. Dr. Prilleltensky delivered an incredibly engaging live speech, where science and humor were woven together in an impactful and relatable way. He was talking directly to us, the members of the global happiness movement in his audience, to which we all belong. What we do, individually to add value to our own lives and that of others’, matters greatly to the expansion of the happiness movement. Together we are Happiness and we are having a joyously fun time on this journey with Dr. Prilleltensky.
