yoga instructor

Our instructors draw from the many disciplines of yoga so our students are able to explore and develop a practice unique to themselves. Each and every one of our experienced yoga teachers bring their own distinct flavor to their classes, yet all contain the fierce passion for and commitment to sharing the practice of yoga with others, and supporting  their students' evolution and growth on (and off) the mat.

The Team

​​Amy Pastore

Amy’s Yoga story began after years studying fitness and martial arts. She stepped into her 1st yoga class at the gym looking for a good stretch and found that it wasn’t exactly love at first down dog. It wasn’t until she became more familiar with the asana and began to use her breath that she began to experience how profound the practice of yoga could be. “When I started linking the movement with the breath, the practice became magical. I had an aha moment and it quickly became apparent that this practice was much bigger than anything I had done in the gym. I was learning how to pause and flow, cultivating an awareness and concentration that would not only serve me on my mat but gave me the tools to act in my life off the mat in a way that was life affirming.”

Amy traded in her boxing gloves for a yoga mat, her gym membership for class packages at her favorite Yoga Studio, Yoga Synthesis and found her first and most influential teacher Raji Thron. Amy’s teaching draws from her many influences. Amy generously shares with her students what has been valuable and what has worked for her from her vast experience. Her most important message to her students, “This practice is a metaphor for life, the mat is a mirror. Each time we come to the mat, it’s an opportunity to learn something about ourselves. Everything we learn on the mat we can take and apply to life.”

Adina Kelman

Yoga found Adina almost 10 years ago. Unwillingly, she let a friend drag her to her first class convinced that this would be the first and last time on a yoga mat. By the end of class she was hooked.
Initially, yoga allowed Adina the strength and flexibility she needed to balance out her passion for running, but she soon discovered that this ancient practice offered more than just a physical workout.
Through the study of philosophy and pranayama, she found a healing practice that has inspired and transformed her, centered and saved her. Adina received her 200 hour training from hOMe yoga with an additional 30 hours in children’s yoga and 50 hours restorative, certifying her as a restorative yoga teacher. She is currently crafting her 300 hours at Laughing Lotus in NYC.
Adina guides students through an active asana practice, providing a well balanced physical workout that ultimately creates space for breath, centeredness, acceptance and connection.

Ann Turi

Ann Turi began practicing yoga in 2008. Focusing on Bikram Yoga for the first two years of practice set her foundation. In 2016 she completed her 200 hour Yoga Teacher Training certification and in 2018 she completed her 500 hour certification both led by Sri Dharma Mittra in New York City. Dharma Yoga is a graceful, yet challenging form of yoga based on Sri Dharma Mittra’s almost fifty years of practice of classical yoga. The practice is appropriate for students of all levels, from beginner to lifelong practitioners and accessible to so many because it meets each student where they are and according to their condition. As students move through the different series, they are encouraged to go deeper and experience the practice in a meditative and spiritual way.

Ann has practiced yoga all over the world. Her practice led her to an ashram in 2013 where she studied at the Kaivalyadhama Yoga Institute, Lonavla, India.

Ann is the mother of two boys, lives in Franklin Lakes, NJ and serves as In House Counsel to a London based pharmaceutical company.

Ben Wisch

​​Ben Wisch

As a multiple Grammy Award Winning Producer and Artist, Ben brings his unique blend of artistry and musicianship along with his passionate commitment to finding the gift in each day to his Yoga Classes, Workshops, and Teacher Training Programs. Formally trained in both Iyengar and Anusara Yoga, he has a strong background in classical alignment and technique and teaches from the perspective of finding optimal balance of strength and grace in the asana practice.

Ben's greatest source of inspiration comes from his ongoing curiosity about his own Dharma and exploration in the laboratory of his own life. His gift is in giving his students the safe, supportive environment to be themselves with all their faults and imperfections and to use their practice as a way to feel and heal, and to embody the realization that what they seek is already inside them; that the practice of yoga is an opportunity to be reminded of the beauty that pulses through each of us in a uniquely individual way. We practice as a community so we can remind each other what we constantly forget.


Eileen Costello

As a student of yoga for over a decade, Eileen can say with confidence it has changed her entire outlook on life, physically, mentally and spiritually. "I was hooked after my first class and have found that as my life has evolved, so has my yoga practice."

After completing her 200-hour Registered Yoga Training with Ben Wisch in 2017 at Flow Yoga Studio she can say with confidence her journey as a student will never end. The idea of taking a traditional practice and making it work for everyone is Eileen's passion.


Eileen incorporates Functional Yoga into her classes, which allows her students to practice postures and movements that will fully support them off the mat. In the end, it's not about touching your toes, doing a handstand or being flexible. It's about supporting your body as you move throughout your daily life, living and feeling really well.⁣

Erica Stanzione

Growing up as an athlete, Erica always felt a strong connection to physical movement. It wasn’t until her mid-twenties that she desired a stronger connection to her emotional self and a deeper sense of fulfillment within that movement. The second Erica stepped onto a yoga mat, she knew that her gym memberships were a thing of the past; She had found that connection she had been yearning for. The sense of release and freedom that she felt after a class was something she knew that she had to share and continue to discover. Erica completed her 200 hour teacher training in March 2014 and dove headfirst into her journey as a yoga teacher. Her hope is that her mistakes and life challenges inspire and awaken something within every student that she crosses paths with. Her passion to serve, love and heal is what feeds her emotionally and forces her to continuously grow as a teacher.

Erica has a tremendous amount of gratitude for her teachers along the way who have challenged her, shaped her and opened her eyes to living a meaningful life. Lastly, she would like to express a very big thank you to her students who allow her to guide them and trust her to hold space for them while they move towards their highest self. Being able to witness the vulnerability and courage of her students has helped Erica realize her purpose in this life and for that, she is eternally grateful.

Jessica Bush

Jessica began practicing yoga in 2001 while living in New Mexico. When she moved to New Jersey in 2002, she walked into a local yoga studio and had the most wonderful feeling of being home. She started to practice more frequently and intently, spending as much time as she could at the studio, even working the front desk while attending graduate school. With the encouragement of one of her teachers, Jessica took a teacher training with David Swenson and began teaching Ashtanga yoga in 2004.

In 2006, she completed a 200 hour training at the Yoga and Healing Center (in Scotch Plains, NJ) and has been teaching ever since.

Jessica's teaching style is rooted in the Ashtanga tradition and incorporates vinyasa flows that build to a particular pose or focus. She strives to create a class that challenges each student yet allows for success no matter what the experience level.

Jessica's yoga practice carries her through every aspect of life helping to keep her strong, healthy, centered and grounded and she finds that it has been a great source of joy to be able to share these incredible benefits with others.

In addition to teaching yoga, and her role as mother of two, Jessica holds an M.S.Ed in Museum Education and spent over a decade working for The New Jersey Historical Society and Ellis Island.

Josh Ehlin

Josh started his yoga journey when his wife asked him to come to a hot yoga class, saying “You’ll love it.”  With some trepidation, he attended his first class.  He was instantly hooked, from the moment he started the class in a peaceful Savasana, a powerful flow, and ending in a sweet and sweaty Savasana.   Loving how yoga made him feel, both on and off the mat, he wanted to be able to share his heart for yoga by teaching.  Josh took his 200 hour YTT certification with Ben Wisch.  With the support of his family, friends, and classmates he finished his training, diving right in to sharing the gift of yoga throughout the community. Josh leads a powerful flow with emphasis on the developing a strong foundation and core strength.
