    Mackenzie Hall

    Founder and CEO, Realign Retreats

    Mackenzie began her career in technology working for Facebook. Her intrigue in early stage startups and entrepreneurs led her to, connecting foreign entrepreneurs with Silicon Valley resources. Her inspiration for Realign Retreats stems from her passion to infuse the tech scene with a more wholesome, balanced, and enlightened approach to living and consequentially, innovating.

    She spent a year exploring spiritual and healing practices throughout India and Southeast Asia, until arriving in Bali, where she found a small tech community surrounded by some of the most talented meditation, movement and healing teachers in the world. She began focusing on ways to bridge spirituality, or connecting with a deeper state of inner discovery and awareness, with people hungry to kickstart their true potential.
