I n s t r u c t o r s

Linda Castronovo                           Venmo: @Linda-Castronovo-1

I discovered yoga while still in high school in a 1979 Runner's World article. I followed the directions and tried the postures because the author promised improved strength, flexibility, and injury prevention. It was just a handful of postures: warrior, triangle, cobra, downward dog, and child pose, but I immediately felt calmer, more centered, and more alive. 

I studied exercise science in college and graduate school, worked as a personal trainer, a wellness/fitness director, and field hockey and lacrosse coach. I was certified as a Kripalu Yoga Instructor in 1991 and continue my study of yoga with many teachers, including Patty Townsend. My personal practice has evolved over the years and now includes daily meditation, pranayama, and asana. I value every opportunity to practice yoga on and off the mat.


Now in my sixties, my classes are moving meditations designed to build strength, flexibility, mobility, and balance. I teach an eclectic mix of many traditions, but my aim is to guide you to your own deep well of gratitude, compassion, and self-acceptance.

Maria Kovalenko                                              Venmo: 

I studied Math, Physics, and Engineering in school and started my career as a programmer before shifting into sales with Microsoft and Oracle. In 2006, I began an in-depth study of Hatha Yoga. The result was stunning. I credit my practice for my second pregnancy because doctors told me I could not have any more children.

Since then, I have been deeply engaged in Kundalini yoga and completed 250 hours of Hatha Yoga at the Moscow Yoga University. In 2019, I completed an 8-week Mindfulness course (MBSR) with Rebecca Eldridge, who trained at the Center for Mindfulness at UMASS Medical School.

I moved to Amherst in 2021 and teach at Hampshire Athletic Club and at Christopher Heights of Belchertown.

In 2022, I completed certification as a Neuro Graphica Instructor/Master and Aesthetic Coach.  This is a unique approach to art and stress reduction. Learn more here: here:

Erin Schifferli                                 Venmo: @Erin-Schifferli

Yoga arrived in Erin’s life in the year 2000. The practice brought healing for her shoulder pain and a newfound sense of wellbeing. She was both inspired and curious! Breathing, balancing, and most powerful of all - being - fostered greater awareness and attentiveness in her life. Discovering this was part of her impetus to deepen her practice and attend teacher trainings to gather further insight. From the first pause on a mat, she sensed the power that Yoga has to offer individuals, communities, and the world. Erin
understood that Yoga impacts the practitioner, as well as the planet; the ripples of the connections continue to grow ever outward. Part of her ripple expansion is to share the practice.

Meditation, movement, and time outdoors in the wonders of Nature support her as a whole person, partner, mother of four, and business owner. Erin is grateful to have learned from many teachers and mentors over the years. She maintains a 500 HR E-RYT with continual life study and an ever evolving daily Yoga practice. Currently residing in Amherst, MA, she offers both in-person and virtual classes, private sessions, Yoga Therapy, Nutrition Education / Counseling, and Doula Birth Services, including birth education /preparation.

Pierre Rouzier                                                  Venmo: @Pierre-Rouzier

Pierre Rouzier is a primary care sports medicine physician is his mid 60s who’s been practicing yoga for over 15 years.  He was introduced to yoga at age 50 by his then college football playing son who started with yoga for injury prevention.  Several years later when his younger son completed yoga teacher training after a number of soccer injuries and said “Dad, I think you’d really like doing this”, Pierre went to the Nexus Institute in Costa Rica for his 200 hour YTT.


His interests lie in yoga for fitness and injury prevention and to help people understand the scope of their injuries and learn adaptive asansas to accomplish their goals.  Pierre has used breathwork for working with anxiety, depression and performance enhancement.  He committed himself to learning more about the chakra system and integrating this into his practice and teaching.  


Pierre’s medical career has focused on “Exercise as Medicine”, helping people make lifestyle changes and work with their injuries.  He is the author of a patient education book, “The Sports Medicine Patient Advisor”, and a children’s book, “Henry Gets Moving”.


One of Pierre’s hobbies is long distance adventure cycling.  He rode from Oregon to Boston in 2016, from New Orleans to Canada in 2018, from Vancouver to the Mexican border in 2022, and from Lands End England to the northern tip of Scotland in 2023.


His classes will be energetic and enthusiastic (regardless of your level and which asanas you choose) and they’ll work on nearly every muscle group and joint in your body.

Ilana Beigel

Ilana Beigel                                            Venmo: @ilanabeigel

Ilana was first introduced to yoga in 1991 in high school gym class, and was instantly enamored with the peace and tranquility the simple yet profound practice offered. She was in awe of the transformation she felt in her body and mind, and while she didn’t yet know the role yoga would play in her life, she knew the story had just begun. 

She formally pursued the field of Psychology and a career as a Medical Speech Therapist, all the while engaging in self-study of yoga, meditation and spirituality. She eventually enrolled in a 200 hour vinyasa yoga teacher training at the Kripalu Center for Yoga & Health - simply because she wanted to learn more, not to actually become a yoga teacher … but as John Lennon said, “life is what happens to you while you're busy making other plans”. 

Now, in addition to leading classes, workshops and private yoga and mindfulness/life coaching sessions in Amherst and online, she teaches on the online platform 'The Thread Yoga Collective' and works as a faculty member at the Kripalu Center where she teaches classes and works in the School of Yoga.


She believes yoga is a way of life - not simply something you do on the mat - and she aims to inspire you to live with more purpose, joy, ease, and flow. In her classes, she encourages you to deeply connect with yourself and her hope is that you will leave practice feeling more vibrant and strong in your body, more calm and relaxed in your mind, and more open and spacious in your heart.

Robin Kassis                                     Venmo: @Robin-Kassis-1

I love that yoga, which is such an integral part of my life, is so portable. I can take it anywhere, whether it's the red rocks of Sedona, the  beaches of Cape Cod, or inside a studio. My practice has deeply informed and transformed my life, and it is a gift to be able to share that with my students, both privately and in classes. I currently teach two group classes on Monday and Thursday mornings at 10:00 and two individual classes over Zoom, as well as occasional workshops. 


My training and certification was completed 25 years ago through the Kriya tradition. But my personal practice began in my early twenties, and became more focused in my forties, when I decided to become a teacher. My style is to address individual needs for correct alignment and respectful engagement. Classes incorporate pranayama or breath practice, which  supports depth in each pose, allowing a student to listen and find his/her edge without going beyond the body's acceptable range.

I love teaching yoga and my hope is to instill that passion and care to my students as they open to transformation in body, mind and spirit. 


In addition to yoga, I am a Usui Reiki Master and am available for private sessions for Reiki and sessions that combine yoga with energy work. As a certified Wholeness Energetics practitioner, I offer spiritual counseling and energy work to support change and empowerment in unpacking old patterns and beliefs. I pull in the methodology of Donna Eden's energy medicine to complement these healing modalities.


Meditation, hiking, reading, singing and spending time with loved ones is the foundation of my life. You can learn more about my work at

Molly Aronson           Venmo: @Molly-Aronson-2


Molly Aronson (they/she) came to yoga and meditation as a way of finding gentle connection with their body and accessing their intuition. Their teaching is informed by the idea that we all have unique, varied, and sometimes complex relationships with our physical bodies, and there is no universal or correct way to be in relationship with a body. Their 200 hour training was with the Tree Yoga Cooperative, a social justice focused and trauma informed studio that empowers students to cultivate their internal guidance both on and off the mat. The Tree focuses on contextualizing the modern practice of yoga within the race, class, and cultural structures we live under today. Molly practices gentle vinyasa, yin, and restorative yoga and weaves elements of these together in their classes. They intend to honor the roots of this ancient practice while also making yoga accessible to a wide range of bodies and minds. Off the mat, you can find Molly birding, biking, cooking, foraging, or playing drums. 


Michael Silverstone           


Michael is a daily home practitioner of yoga, and other meditative practices including Yoga Nidra guided relaxation. In 2020 he trained and received instructor certification in a 200-Hour RYT Vinyasa Yoga program.

He began a daily home practice in response to the challenges of the pandemic, and found in yoga a source of well-being, resilience and calm that drew him to outdoor community practice. As a yoga instructor, he delights in being able to encourage and support the practice of yoga in an outdoor setting, and in providing modifications that offer opportunities for both easier access to poses and for challenge.

A lifelong teacher, Michael is a lead Montessori classroom guide in a Lower Elementary classroom.  In addition he works with adult learners seeking Montessori certification in his role on the teaching faculty of the Montessori Elementary Teacher Training Collaborative (METTC).
