There are scores of yoga teacher training instructors in Denver, too many to count. Every trainer is unique and hopefully has something very valuable to share with you. Here is the list of our primary instructors. Perhaps you can see yourself learning from what they have to offer.

Derik Eselius (ERYT 1000) – Lead Trainer

I first encountered yoga in 1991, just after High School, on an extended journey around the globe.  India was one of the stops, where I first met Baba Hari Dass, a lifelong yogic adept. I had arrived at the inception point of a lifelong commitment and quest.

Since that time, I also studied asana with world-class teachers including; Ramanand Patel, Tias Little, and Richard Freeman.  I credit Yogarupa Rod Stryker (whom I met in 2011) for teaching me tantric Hatha Yoga practice. Baba Hari Dass taught me the internal practice of Raja and masterfully demonstrated the spirit of karma yoga.

Both Baba Hari Dass and Yogarupa elevated my practice spiritually and taught me to live more graciously in the world, be more loving, and contribute more fully to society and students.
