Laura Ahrens

Yoga & Meditation, Faculty

In her work, physically challenging asana kindles the fire of transformation and focuses strong attention into meditation. Storytelling, metaphorical language, and precisely directed options for alignment teach the tale of our becoming more human.

Laura loves teaching others to be discerning practitioners who synthesize information for themselves. In that spirit, she co-created The New School of Yogic Arts, a teacher training school for those who want to learn to teach the practice of yoga as a living system that breathes differently in each body. Her current work is a melding of all the different truths of moving and living in yoga that she has had the privilege of learning. Her teaching is an approach to practice and is not style focused. Her classes and other offerings prioritize attention to breath and commitment to the inner work necessary for personal evolution. Laura’s greatest commitment is living the practice of yoga in the world, and to teach others to do the same.

Her 500 hour training with her teacher Sarahjoy Marsh concentrated on yoga therapeutic concepts at the intersection of tradition and science, emphasizing neuroscience, interpersonal neurobiology, adaptive yoga, and yoga psychology. She also holds a 200 hour certification in Hatha Vinyasa, 200-hour and advanced certifications in Forrest Yoga taught by Ana Forrest, and completed a year-long mentorship under the guidance of Dr. Heidi Sormaz. She holds a BFA from The University of the Arts, where she honed her own use of story and song, which, since ancient times, has served as instruments of connection and community. Her teachers have paved her path, and she is forever grateful to them and to the teachers of the teachers.

Cameron Davis

Cameron Davis

Environmental Art, Faculty

Cameron Davis (Cami) is a Senior Lecturer with the University of Vermont’s Department of Art and Art History. She teaches painting, drawing, and courses on art, ecology and community. Her own work includes painting, performance, installation and community art activist projects exploring issues of conscious perception as fundamental to living sustainably in a warming world. She considers her painting to be her primary conversation from which the wider community projects evolve.

In 1999 Davis and artist Sally Linder created the community art Temenos Books Project and event For Love of Earth, A Celebration of the Earth Charteras a way to introduce the Earth Charter, an international document that outlines principles for building a just, sustainable and peaceful global society. With over 22, 000 participants, Linder designed and painted the Ark of Hope as a holding place for the Temenos Books. They traveled to four continents including Johannesburg South Africa for the World Summit on Sustainable Development, Bangalore India for the 2005 International Women’s Conference, and to the Netherlands, for the Earth Charter +5 event, where 8000 children and Queen Beatrix participated in creating books.

Davis continues to collaborate with artists, filmmakers, poets, students and the public including the Quantum Community Project, a participatory ecological event of film, poems, veiled drawings, and yoga practice, created with Metta Earth Institute Co-Director Gillian Kapteyn Comstock.

Davis’ solo and community work addresses climate change. Waxwing Medicine 2006, Messages to Earth 2007, Let Ours Be a Time Remembered 2008, and the Dear World Project 2009, part of the Human=Landscape, Aesthetics for a Carbon Restrained Future exhibition at Burlington City Arts, Burlington, Vermont, were all responses to climate activist events.

In 2013 Davis created 12 large scaled paintings titled Endless Spring as the stage set for the Emergent Universe Oratorio composed by Sam Guarnaccia. The work represented a three-year collaboration between Sam Guarnaccia, Paula Guarnaccia and Davis collaborating with writers on the Oratorio’s content to articulate a “new story” of shared purpose and emergent possibility at the threshold of the Anthropocene era, where human’s impact is now the major evolutionary driver of Earth’s future. They worked closely with Mary Evelyn Tucker and John Grim using the book and film, Journey of the Universe by Brian Swimme and Tucker, as the framework for the Oratorio.

Currently Davis is working with Ben Bach, Cinematographer, and Fletcher Bach, Creative Technologist, on The Orchard Project: video sketches for the 2015 exhibition, Eyes on the Land, 14 Artists Paired with 14 Vermont Land Trust Properties, Pizzagali Center for Art and Education, Shelburne Museum, Shelburne Vermont.

Hasita Agi Nadai

Hasita Agi Nadai

Ecological Leadership, Faculty

Hasita Agi Nadai was born in Vienna, Austria, grew up in Italy, and immigrated to the USA in 1953. Her deep connection with Nature started in her early childhood. She has spent most of her life enjoying Nature through mountaineering, trekking, skiing, and canoeing.

The desire to investigate Nature in all its dimensions led her to earn a Master’s Degree in Cell Physiology at Columbia University and in 1987 to a Master’s Degree in Geology at the City University of NY. She taught and did research in both fields. She recently retired as a project manager for the U.S. Environmental Protection Agency. In 1987 Hasita became involved in Yoga. She is a Professional Level Kripalu Yoga Teacher and  since 1994 she has taught at the Rivertown Center for Yoga and Health for adults and children. She teaches yoga privately and also as a substitute in other centers.

In 1990 she became involved in the Deep Ecology movement. She trained with Joanna Macy and follows the teachings of Thomas Berry and Brian Swimme where ‘our story’ is the story of the evolving universe. Hasita has created Yogagaia, which is about connecting with our body and to our story, based on science – the story of the Universe. Through asanas, dance and meditations, we reawaken the memory of our Kosmic Journey (Kosmic=matter, body, mind, and spirit). It is a journey filled with miracles, and Yogagaia brings to our consciousness our place in the web of life and how we are all co-creators of the irreversible evolutionary spiral of the universe. Hasita gives Yogagaia workshops to various audiences; at the Loyola Marymount University, Lehman College, and several high schools, at the Green Mountain Monastery, Hebrew Learning Center, and organizes programs such as ‘Yogagaia and Hiking’ in the Italian Alps.

Since 1992 Hasita has been facilitating courses on Deep Ecology, Voluntary Simplicity, and Sustainability, developed by the NW Earth Institute at the Environmental Protection Agency. In 2001 she created the  Green Yoga Sangha in Westchester County, New York, which meets monthly to discuss selective readings to deepen their understanding of the journey of the universe, to learn about their impact on the health of the planet led by the present world economy, and to explore how they can evolve into healing our planet.

Hasita is co-founder of the Green Yoga Association

Since 1994 Hasita has been involved in the energetic healing arts. She is a Reiki Master and is trained in Energy Medicine Healing as taught by Jacque Tombazian.

Mikki Raveh

Mikki Raveh

Yoga & Meditation, Faculty

Mikki Raveh is a mother, a teacher, who values the importance of stepping outside the everyday and exploring the energetic possibilities of the world that surrounds her. Mikki met Russell and Gillian in 2007 when she spent her first summer in Middlebury. From the moment she visited Metta Earth she fell in love with everything about it and knew that she had to share this sacred place with others — Mikki has been co-creating magical retreats with Gillian and Russell ever since. 

Mikki currently lives in New York City, and spends her summers in Middlebury, where her husband teaches at the Middlebury Language Schools.

She completed her yoga teacher training at Baptiste Power Yoga Institute with her Boston mentor, Gregor Singleton. In the summer time she teaches yoga in Hebrew at the Middlebury Language Schools, studies with Russell, and works closely with Gillian and Russell at Metta Earth. It was in Vermont that she was also first introduced to the Iyengar system, and upon her return to New York City in 2010 Mikki began her practice and study at the Iyengar Institute. Mikki is also inspired by Marco Rajas’ teachings and continues to grow from his influence.

In addition to her yoga training, Mikki was certified in the Pilates method in 2001 through Physical Mind Institute, Power Pilates, and the Pilates Method Alliance.

Ossi Raveh

Yoga & Meditation, Faculty

In 1992, Ossi Raveh was a high school student. She was a serious dancer, a gymnast and part of the theater crowd.  While working on the lighting for the schools play Ossi stepped on a weakened section of a catwalk which gave way beneath her.  She fell 40 feet and landed on a concrete floor.  Ossi suffered many major injuries including, a concussion, compound fractures to her wrist and elbow, two broken knees, a pelvis fractured in four paces, broken jaw & sinus bones and shattered teeth. After multiple surgeries, weeks in the hospital and many painful hours of rehabilitation Ossi was told she would never dance again, let alone walk without a limp.

Ossi refused to accept this.  In the spring of 1993 she was introduced to Pilates as a form of movement therapy. Pilates was a game changer. Within months Ossi was not only able to walk without a limp, she was able to dance again!  Pilates not only helped her to recover, but it acted as a stepping stone to other movement based modalities. Over the next decade Ossi would become a certified  Pilates instructor through The Pilates Studio, Inc. and also complete her training in the Gyrotonic Expansion System and Gyrokenisis with Julio Horvath. While traveling to Thailand she studied Thai Massage, reflexology and upon her return became a certified Doula.

In 2004, while studying to become a Licensed Massage Therapist,  Ossi took her first Heated Vinyasa Yoga class and has been back to her mat every day since. The pace and fluidity of the heated vinyasa flow helped her build strength, hold on to her flexibility and calm her mind. More importantly it forced an alignment in her body that helped soothe her injuries.   After many years of receiving this multi-faceted practice from many inspiring and incredible teachers Ossi completed her Level 1 and Level 2 yoga teacher training with Baron Baptiste.

Now, with nearly twenty years of teaching various modalities under her belt, Ossi had the desire to take her students further and explore movement beyond the Asana. So she created a flow based on all the modalities she has been teaching and practicing for almost half of her life. It utilizes the core strengthening of Pilates, the spiraling energy of Gyrotonic and the grounding movement, meditation, and heat of yoga. This combination brings a naturally balanced energy to all of her classes and creates a flow that is adaptable to all students.

In the winter of 2014 Ossi brought her flow to the Carroll gardens neighborhood of Brooklyn and opened the Brooklyn Yoga Project. It is not just another yoga studio.  It is an intimate, boutique-style space offering daily heated and low-heat yoga classes, workshops, teacher trainings and community gatherings where the eight limbs of yoga are studied, shared and celebrated. It is a safe and personal space to explore, breathe, move and experience all that yoga has to offer.

Ossi truly believes that a yoga practice doesn’t start and stop on your mat. It is something that merges your mind, body and soul and spreads into every part of your life.
