About the Instructors
Lonnie Stanton (Yoga) first discovered yoga while studying at the Boston Conservatory where she received her BFA in Dance. Post graduation, she was drawn to yoga classes as cross training to her dance career and realized the practice was providing much more than physical benefit; she was hooked. Lonnie firmly believes yoga is for everyone and provides needed space; space found physically through posture and breathing techniques, mentally through a guided meditative flow, and emotionally through the individual choices made on your mat. She is sensitive to providing options that cater to where each student is that day and values music as an atmospheric aid and driving force in each class. Her hope is to guide individuals to experience a heightened level of body awareness that can translate to a greater self awareness beyond the studio.
Jessica Smith (Pilates Mat) is a comprehensively certified Power Pilates Instructor. Jessica relies on Pilates to keep her professionally-dancing body strong, injury-free, and available for new opportunities where movement information as well as everyday life encounters are concerned. She completed her Pilates certification in North Carolina and has been teaching since 2012, most recently for the last three years in Jamaica Plain and Cambridge. Jessica firmly believes that Pilates is for every body. Whether you are looking to improve your posture or you are training for the next great athletic achievement in your life, a regular Pilates practice will only increase your chances for success! Joseph Pilates said “In 10 sessions you will feel the difference, in 20 sessions you will see the difference, and in 30 sessions you will have a whole new body.”

Alice Heller (Nia)  has been dancing for most of her life. Her focus for 2017 is on Nia, early movement education and African dance. She has been working with children and adults for over 20 years. Starting with the classic dance genres, she moved into African dance and studied seriously for 25 plus years performing and teaching. She teaches at schools, public studios and privately.

Besides African-based dance and drumming, Alice’s studies moved her to work with children in preschools and private class settings. She has taught jazz, creative movement, hip hop, improvisational dance, gymnastics and in the past 5 years, internal martial arts and  The Nia Technique (Blue belt instructor).

Eva Sevian Sklaver (Yoga + Family Yoga)

Eva grew up in Boulder, Colorado, loving the fresh air and Rocky Mountains. She grew up dancing, first: Ballet and then was fortunate enough to be a part of the the early years of Modern Dance. As an early teenager she began to run competitively and left the dance world for the running trails of cross country running. After many years of running, and multiple injuries, training for marathons and half marathons, she came to yoga when she was pregnant with her first of three children, 16 years ago, and fell in love with yoga.
Eva has continued on her yoga journey for the balance that it has brought to being a mom, informing preventing injury so that she could continue to move in a healthy, happy way, and sheer joy of loving the practice of yoga and the constant growth yoga offers on multiple levels. She got her 200 yoga certification at South Boston Yoga and is now working towards her 500 hour yoga certification at YogaWorks, and has been regularly teaching for a few years.Eva is a former Special Education teacher and brings to yoga patience, understanding, and a deep appreciation for all that walk into the room wanting to learn to strengthen, and grow on their yoga mat and walk off with that depth, growth, and deeper understanding that yoga had brought to their lives, and into their world.
In addition to practicing and teaching yoga, Eva is also an artist. She have dabbled in many art forms, painting, drawing, small metal and ceramics.  She has designed and made jewelry for many years and sold my work in 18 stores and galleries in the Boston area for about a decade.
