Retreat Guru Team – About Us

We believe all human beings are innately wise, strong and kind. This wisdom, although not always experienced, is always present.

Going on a retreat can be a skillful way to reconnect to one's basic sanity. But putting on retreats is hard and complex work. We believe that retreat centers should have state of the art digital tools that allow them to work as effortlessly as possible. Our mission at Booking Guru is to help retreat centers thrive.

Our company started in 1998 building websites and booking systems for spiritual retreat centers and teachers. We are located in beautiful Nelson, BC Canada. It is a truly amazing little town to live and work in while providing booking software for retreat centers throughout the world.

Olivia Stille

Product Manager

When Olivia discovered so many of her loves coming together in this mindful, mountain-town, tech company she thought, ‘Could this be real?’. It was! So she packed up her life in the big city and moved to Nelson where she now gets to live & work in alignment with her true self.

Eli Finer


Eli joined the Israeli army programming division thinking he knew how to code. He didn't. One would hope he learned a thing or two in the 20 years since. He combines his misguided perfectionism with his critical nature to make people happy and occasionally, himself, miserable.

Andy Chute


Andy loves making cool software and has been programming since he was in high school with Shayne. He also enjoys working around the house and gardening with his wife and cat.

Steve Strom

Growth Team

Steve's walk of life has been in corporate software, yoga, world travel, and living in retreat centres. He is passionate about conscious business, retreats and people finding connection to self. Steve is stoked to help bring to life the vision of growth and awakening at Retreat Guru.

Dennis Marriott

Success Architect

After serving in senior roles with multiple major holistic learning centers, Dennis decided to work for them all, and joined Retreat Guru. A voracious generalist, his management career has spanned technology, hospitality, arts and culture, and sport and leisure. He loves the journey.

Diana Garroway


Diana left the high-tech world 10 years ago to pursue a life with less stress and more fun. She filled her days with sun, ski, travel and ownership of a small hotel. Arriving in Nelson, she tumbled upon the team at Retreat Guru. She was so enchanted by the match of code and purpose, she dove right in.

Grant Cherwenuk

Customer Support

Grant's path has gone many places. He's pleased to have found a home in Nelson and a purpose at Retreat Guru. If he's not offering a smile and a helping hand to customers, Grant is often challenging himself in the mountains learning in the company of laughter and good times. He loves sharing their lessons in his interactions with everyone.

Rachel Selkirk


Rachel explored the professions of teaching and project administration before taking her love of problem solving and diving into to software development. Skier, mountain biker, climber, and thrift store enthusiast, she enjoys the good life in the Kootenays.

"Our communication and efficiency has greatly improved with Retreat Booking Guru now that we have the ability to accept credit cards online and schedule automatic notification emails."
