Meet the Founders:
Happy Jack and Happy Hanna

Hello! We are Hanna and Happy Jack, the founders of Happy Jack Yoga. Happy Jack Yoga is a community of yoga practitioners and teachers. Thank you for your interest in our work.

In 1980, due to his smiling and joyful presence, Happy Jack was aptly named by his parents. As Happy Jack grew up, he was bullied, teased, and subsequently lost his blissful nature. Years later, through the practice of yoga, his high vibes returned. Thus, in 2010, Happy Jack Yoga was born. 
At Happy Jack Yoga University, we empower students to discover their authentic voice, inner confidence, and step into their full self-expression. 

We're an online yoga school where you get certified from the comfort of your home while continuing to work and be with your family.

We lead online teacher trainings with together with a team of passionate facilitators and experts. We're thrilled that you are here 😍

Co-Founder and Director of Education, Happy Jack Yoga
Graphic Designer (Istituto Europeo Di Design, Milano, Italy)
Grief Support Practitioner
Integrated Yoga Psychotherapist in Training
E-RYT 500

Hanna von Hafenbrädl is the co-founder and creative director of Happy Jack Yoga. Hanna’s yoga journey began in 2007 when she very unexpectedly lost her husband to a virus. The sudden loss turned her life and her future upside down, and today she sees her grief process as her superpower. When Hanna found yoga, she immediately fell in love with the philosophy and the asana practice. Today she uses yogic tools creatively to address trauma, loss and mental health by offering yoga teacher trainings online and around the globe with Happy Jack.

Today Hanna recognizes that her healing has happened gradually, although she knows she wouldn’t be who she is today if it wasn’t for her deep desire to study yoga, mental health and spirituality. Through the grief process, combining therapy and yoga, Hanna was also able to reconnect the dots from her childhood difficulties and find her own inner power. Hanna now dedicates her life to being of service to others. She is fluent in seven languages and aims to create a welcoming space for everyone she meets.

Hanna studies under both Western and Indian yoga masters. She is currently studying grief therapy and Masters in Integrated Yoga Psychotherapy in London, UK.

Dr. Edwin Bryant, PhD

Professor of Hinduism, Rutgers University

Edwin Bryant received his Ph.D in Indic languages and Cultures from Columbia University, where his thesis culminated in his first book: The Quest for the Origins of Vedic Culture (Oxford University Press, 2001). He taught Hinduism at Harvard University for three years, and is presently the professor of Hinduism at Rutgers University where he teaches courses on Hindu philosophy and religion. He has received numerous awards and fellowships, published eight books, and authored a number of articles on the earliest origins of the Vedic culture, yoga philosophy, and the Krishna tradition. These include a Penguin World Classics translation of the story of Krishna’s incarnation, from its traditional source the Śrīmad Bhāgavata Purāṇa.

As a personal practitioner of bhakti yoga for over 45 years, a number of them spent in India studying with traditional teachers, where he returns yearly, Edwin strives to combine academic scholarship and rigor with appreciation towards traditional knowledge systems. His teaching method is to allow the ancient texts to speak in their own voice and through their own terms and categories.

Edwin’s translation of and commentary on the Yoga Sūtras of Patañjali (Farrar, Straus & Giroux, 2009) is specifically dedicated to contributing to the growing body of literature on yoga by providing insights from the major pre-modern commentaries on the text with a view to grounding the teachings in their traditional context. Edwin’s most recent published work is a sequel to this by the same publisher entitled Bhakti Yoga: Tales and Teachings from the Bhāgavata Purāṇa (Farrar, Straus & Giroux, 2017). This work, too, seeks to ground the practices of bhakti in the traditional Krishna-centered framework of the Vrindavan devotional traditions.

Edwin is presently working on a translation of the Bhagavad Gītā with a commentary based on the insights of the principle traditional commentators (viz, in the same vein as theYoga Sūtras commentary). The Gītās teachings in many ways serve as a link between those of theYoga Sūtras and those of the Bhāgavata Purāṇa in the Bhakti Yoga volume, and upon completion will conclude Edwin’s vision of a Trilogy of Yoga texts offered to scholars, students, practitioners, and the intellectually curious.

He is also co-authoring a book entitled ‘In Defense of a God with Form,’ and working with his sister on translating his Penguin translation of the 10th book of the Bhāgavata Purāṇa into Italian (their mother language).
