Yoga Lineage

Our approach to Yoga adapts the tools and techniques of yoga to the individual and group. Our philosophy is to keep the time-honored and authentic tradition of yoga alive and relevant for the modern context. We transmit teachings consistent with the lineage of Viniyoga™, as transmitted to us by Gary Kraftsow of the American Viniyoga Institute. Gary’s teacher was TKV Desikachar, the son of “the father of modern yoga,” T Krishnamacharya.

Distinguishing features of this approach include:

– breath-centered movement

– use of repetition and stay in postures (asana)

– functional benefit of the posture (asana) over an exact form

– safe and intentional sequencing of practices

– adaptation of yoga tools and techniques for the practitioner and group

– a comprehensive set of yoga tools to assist the practitioner including asana, pranayama, meditation, sound, yoga philosophy, nyasa, mudra and more

The trademark for the term, Viniyoga is the property of Gary Kraftsow and the American Viniyoga Institute.


The journey in the 200 hr. Yoga Teacher Training begins with a focus on you and your personal practice as a means for understanding and living yoga. From that foundation, you will learn and practice the most important skills for teaching so that you can facilitate yoga for individuals and groups.



The 300 hr. Advanced Yoga Teacher Training is a springboard for deepening knowledge, personal practice and teaching skills for asana adapted to the individual and groups, pranayama, meditation, sound, mudra, nyasa and  other symbolic aspects of yoga practice.

What Participants Said Was the Most Valuable Aspects of the 300-hour Advanced Teacher Training:

Our Sangha

Mary letting us know that we can be who we are!

The ‘shifting” that I can sense is happening because of the program and all the resources you shared

Mary made me feel welcome and part of the group.

I loved the sutra lessons and chanting taught in an accessible way.

Breath ratios and techniques

The homework after the lectures and book resources, to learn more deeply and integrate the teachings.

I did like the continuity with the same students from start to finish.

Having a safe place to go beyond my comfort zone, even beyond my ‘window of tolerance’ to fin my current edges.

What Participants Said About How They Developed as a Yoga Teacher as a Result of the Training:

I see more possibilities.

I learned more about taking care of myself so I can show up for students.

Increased confidence and ways to build confidence.

Developing sequences

Finding ways to develop an idea using teaching principles so it is digestible.

A deeper understanding of what is important to me and how to care for myself with tools of yoga.

Taking care of self to be able to teach others.

Practicing and studying the sutras is helping to ground me more in my teaching.  Reflecting more deeply on the sutras and their meaning and application in life has strengthened my teaching.

I plan my classes both sequence and breath and add other things like philosophy that I never did before.

I feel confident offering new things and have learned so much.  I feel like I have people with me and backing me as I teach.  The sangha is with me at my studio; before I felt more alone and not supported and that kept me from sharing deeper teachings.

More experience with deeper teachings.  More confidence to teach these deeper teachings to others.
