Founder

Adrienne Heim, M.S.Ed.
FOUNDER & EXECUTIVE DIRECTOR

Adrienne is the founding executive director of Green Generations. In just five years, GG has grown under Adrienne’s vision and direction from a concept to thriving partnerships with eight schools throughout New York City and programs for hundreds of children.

An educator for 15 years, GG is Adrienne’s life project built on an educational foundation that began in the South Bronx in 2002 where she worked as a bilingual elementary Teach for America corps member. She then continued teaching at Living School, an award-winning Ashoka school in Paris, France, as the lead English teacher and administrative coordinator. Adrienne has always been passionate about transforming public education and putting into practice holistic, whole-child centered education. Green Generations marries these two passions to help children realize their potential and effect social change.

Adrienne has a Master’s of Science in Education with an extension in bilingual education. She is also a New York State certified elementary teacher (Pre-K – 6), holds a certificate from New York University’s George H. Heyman, Jr. Center for Philanthropy and Fundraising, is a certified yoga teacher for children, and participated in NOAA’s Teacher at Sea program.

Previously, Brook worked as the managing director of a large, 24-hour emergency veterinary hospital in Connecticut where she oversaw day-to-day operations and helped in strategic planning for the future expansion of the practice.

Brook holds a Master of Public Administration in Environmental Science & Policy from the School of International and Public Affairs at Columbia University and a Bachelor Degree of Science in Biology and Environmental Science from Fairfield University.

joelle-charles

Joelle Charles, B.Ed.
GG FACILITATOR

Joelle has been an educator since 2006. Having grown in up a household that began its own educational nonprofit, Joelle has experienced both sides of the coin: life as a student and life as an educational leader. From this beginning, she has adopted a teaching philosophy which identifies children as the most valued participants in a classroom. She believes in the domino effect where one’s action has a ripple effect. Because of this, she purposefully makes her actions full of kindness, respect, patience, and integrity.

Joelle’s interests in emotional well-being, feminism, and communal healing make their way into her classroom by way of art projects, movies, games, and yoga instruction. She cares deeply about creating spaces for children to be able to learn, grow, and make mistakes without the fear of being judged or ranked.

With this being her first year at Green Generations, Joelle looks forward to carrying on the mission of giving to students the tools they need for emotional management. She is confident that her time with GG will be full of laughs, love, and raising awareness about the importance of student confidence and mental health.

muriel estevez

Muriel Estevez, M.A.
GG FACILITATOR

Muriel has always followed her passions: first for higher learning which led her to pursue a Master’s in Psychology in Education at Columbia University in 2015; then, for volunteering her efforts to help develop New York City’s environment and undeserved youth, specifically in Harlem; and finally for yoga, which eventually led her home to Laughing Lotus, where she discovered Lotus Flow and Ayurveda. Muriel completed her 200-hour yoga teacher training at Lotus in 2016. With a master’s degree in Spirituality, Mind and Body, Muriel loves to infuse her classes with themes that arise from her studies in psychology and her training in yoga therapy, which includes launching a “Kindness Club” for middle schoolers at a community garden in Harlem. She is continually inspired by how these practices bring people together and create community. She believes deeply that the practices of yoga, mindfulness and intention can teach us to live our lives with balance, and grace, if we are willing to do the work.

As a native New Yorker, Muriel is thrilled to bring her passions to Green Generations and give back to children in the public school system.

Ally T

Ally Tufenkjian
CURRICULUM ADVISOR

Ally originally came to New York to pursue an acting career, but began to feel that her work should serve a higher purpose. While studying Theater and Psychology at Eugene Lang College in the New School for Liberal Arts, she tackled weighty topics such as privilege, systemic oppression, and cultural insensitivity. Inevitably, she saw these issues infiltrate her work as a theater practitioner, educator, and activist.

Ally found that education offered the most promising pathway for change. She first entered the urban education scene in 2011 as a founding member of Healthclass 2.0, a fitness and nutrition program dedicated to serving low-income public schools. Remaining passionate about the arts, she began working as a Teaching Artist in 2013, working with organizations such as the CUNY Creative Arts Team, the Young Players Theater, and the Community-Word Project. She was also a Trainer at Global Kids, Inc. where she built curriculum and led workshops on youth leadership, human rights, and environmental awareness.

In 2015, Ally became a Green Generations facilitator and moved to Texas to pursue her M.F.A. in Drama and Theater for Youth and Communities at The University of Texas. She continues to offer her expertise in curriculum development to GG.

After earning a B.A. in Women’s and Gender Studies at Columbia University, and completing her research as a Graduate Fellow at the Consortium on Gender, Security, and Human Rights in Boston, Julie returned to New York City with aspirations to combine her analytical and academic background with her love of teaching children. She did so most recently as a Trainer at Global Kids, Inc. where she worked with middle school youth in Washington Heights, creating and facilitating interactive workshops that broke down complex environmental and social justice issues.

As a visual artist, Julie believes that aesthetics have tremendous power to promote peace and wellness. For nearly 2 years Julie was a Green Generations facilitator and is thrilled to continue contributing as she pursues her M.Ed. at Temple University.

laura-epperson

Laura Epperson, B.S.
CURRICULUM ADVISOR

As an artist and educator, Laura is passionate about empowering young people to find, cultivate, and use their innate creative voices as they collaborate to build engaged, active, and compassionate communities. While studying Theatre Performance at the University of Evansville, Laura ran an after-school theatre program at a local elementary school and began to explore her interest in alternative education at organizations including Living History Farms and the Santa Fe Opera.

Since moving to New York, Laura has been on a constant quest of finding ways in which she can simultaneously use her artist, educator, and activist selves. As a result, she has gotten to work with incredible young people all around the city. From in-school, drama-based literacy residencies with the Creative Arts Team, to after-school, arts enrichment classes with Wingspan Arts and SOOP Theatre Company, Laura’s work aims to exercise participants’ empathy as much as their confidence. In addition to facilitating classes and workshops, Laura recently created an original emotional health curriculum for NaliniKIDS. This 10-unit, grade-specific curriculum aligns with the Common Core to teach Elementary students emotional agency, mindfulness, self-love, and gratitude.

Laura was a Green Generations facilitator for a year and continues to offer her expertise in curriculum development. In 2017, she joined GG colleague Ally Tufenkjian to also pursue her M.F.A. in Drama and Theater for Youth and Communities at The University of Texas.
