The Founders
Happy Jack and Hanna
Happy Jack Yoga is an educational institute and high-vibe community of yoga teachers, practitioners, and spiritual seekers.
In 1980, due to his smiling and joyful presence, Happy Jack was aptly named by his parents. Interestingly, the goal of yoga is to reveal our blissful true nature.
However, as Happy Jack grew up, he was bullied and ultimately lost touch with this blissful nature. Years later, burdened by the stress of a corporate career, his Mom recommended he try yoga. You guessed it, he fell in love!
In 2010, inspired to share the transformational practice of yoga with others, Happy Jack Yoga was born.
Whether you're here to deepen your yoga practice or eager to be a certified yoga teacher, we offer a rich array of immersive courses and a vibrant, supportive community.
We're thrilled that you're here. 😍

Tony Robbins Trainer
Happy Jack is the Founder & CEO of Happy Jack Yoga; an educational institute providing yoga teacher training courses, leadership programs, and support for a global online community of teachers and spiritual seekers.
At a pivotal moment in life, Happy Jack left a ten-year engineering career at John Deere to take a one-way flight to India. There he spent a year traveling, studying the traditions of yoga and meditation, visiting sacred temples, participating in local religious/spiritual ceremonies, and living within many religious communities: Buddhists, Sikhs, Christians, Muslims, Hatha Yogis, and Hare Krishnas. This spiritual journey awakened a longing to understand the deeper purpose of yoga.
Happy Jack is no stranger to adversity having overcome alcoholism, drug abuse, obesity, divorce, and cancer. He is grateful for each of these life experiences as they allow him to connect with others who have faced challenging life situations. Perhaps the two most meaningful decisions were getting sober in 2009 and becoming vegan in 2011. Since cleaning up his lifestyle, getting clear on his vision to serve, and pursuing his passions, Happy Jack Yoga has been leading transformational yoga retreats and teacher training around the world.
Happy Jack has received the highest levels of education in Yoga, Leadership, High Performance, Vocal Expression, and Spirituality. As a scholar of Sanskrit, Yoga Philosophy, and Bhakti at Harvard Divinity School—where he meaningfully engages the sacred yogic texts and lives in a traditional ashram—these rich experiences are shared with our HJY community.
Outside the traditional yoga circles, Happy Jack is regularly invited by Tony Robbins—his Platinum Partner and mentor—to deliver yoga education to tens of thousands of students at his programs. In addition to teaching yoga, Happy Jack regularly serves as a Trainer for Tony Robbins at his world-renowned personal development programs.
Any experience with Happy Jack will inspire you to be the greatest version of yourself. Journey into profound self-inquiry, deep connection, powerful vinyasa, and a musical experience that will open you up to new possibilities on your mat and in your life!

Hanna von Hafenbrädl is the co-founder and creative director of Happy Jack Yoga. Hanna’s yoga journey began in 2007 when she unexpectedly lost her husband to a virus. The sudden loss turned her life and her future upside down, yet today she sees her grief process as her superpower.
When Hanna found yoga, she immediately fell in love with the philosophy and the physical practice. Today she creatively uses yogic tools to address trauma, loss, and mental health by offering yoga teacher training online and around the world with Happy Jack Yoga.
Hanna recognizes that healing happens gradually, and knows that she wouldn’t be who she is today without a deep desire to study yoga, mental health, and spirituality. Through the grief process, as well as combining therapy and yoga, Hanna has reconnected the dots from her childhood difficulties and found her inner power.
Hanna has dedicated her life to being of service to others. She's fluent in seven languages and aims to create a welcoming space for everyone she meets.
Hanna studies under both Western and Eastern yoga masters. She's currently studying grief therapy and a Master's 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 Gītā‘s 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).
