Prana Das Yoga Teachers & Staff

Prana Das Yoga is proud to enlist a staff of practiced and accomplished teachers with a variety of backgrounds and diverse training focus. Unlike any other center in the area, our teachers have either accomplished or are working towards their 500-Hour RYT status or its equivalent in their healing arts field. We consider ourselves carriers of a long and honored tradition of yoga passed on over thousands of years by many elevated teachers.

With that mindset, we strive to provide the highest standards of teaching, to continue life-long training that may be shared with our students and to make yoga accessible for each and every person who comes to practice. We encourage you to consider this practice a lifelong journey and to take each day as an opportunity for continued education.

Meet Our Yoga Teachers

Nadia Hopkins

Student, Teacher, Adventurer

Nadia is grateful to her teachers, Mary Flinn, David Swenson, David Newman and Shelley Washington, for continuing to guide her through a lifelong journey in yoga. Over fifteen years of practice has enabled her to transform her life, body and connection to the Divine. She has a deep dedication to sharing these same joys with students through dedication to tradition, appreciation of fundamentals and experience of the teachings of the practice. Nadia has practiced with and learned from many spiritual gurus, including Kim Mazzella, Maleah Jacobs, Ainslie MacLeod, Lawrie Hart and Patricia Pearce, among others. This has included intuitive development, energy and chakra therapy, past life regression and reading, diverse combinations of affirmation and manifesting practices, aromatherapy, Native American dreamwork and journeying, prayer, meditation and self discovery. She has also worked extensively with those recovering from trauma, emotional turmoil, conflict and addictions to help them return to balance.

Derek Hopkins

Student, Teacher, Adventurer

Derek's own pursuit of self-actualization did not begin in a yoga studio. An accomplished athlete with a penchant for contact sports, Derek began mixed martial arts training at age 21. Soon thereafter, he started teaching Brazilian Jiu Jitsu and Muy Thai and competing at a professional level. At 23, Derek suffered a debilitating bucket meniscus tear and was told that invasive surgery was his only treatment option. Upon the convincing suggestion of a friend, Derek skeptically agreed to try yoga for the first time in an attempt to rehabilitate his knee and avoid going under the knife. Derek experienced marked improvement in the condition of his knee after only three weeks of yoga practice. Profoundly impacted by the physical results, he began to incorporate yoga regularly into his mixed martial arts training and teaching routines. In 2010, Derek decided to transition from student to practitioner and enrolled in an intensive Teacher Certification Program at Dhyana Yoga. Immersed in his training, Derek started to experience unanticipated and powerful meditative, restorative and therapeutic benefits. He began to enjoy a newfound feeling of global connectedness and mental clarity. Derek credits yoga with helping him to develop mindfulness and increased levels of emotional awareness.Derek has been instructing since 2010 in the Philadelphia area and hosting seminars on benefits of yoga and meditation. His teaching is significantly influenced by Tim Miller, David Swenson and Richard Freeman. Derek specializes in working with individuals dealing with a wide array of physical limitations and injuries to help them return to their optimum health. His team clients include the University of Pennsylvania Women's Rowing Team and the University of Pennsylvania Men's Wrestling team.

Vivi Mazzone

Prana Das Instructor

Yoga has been a part of my daily life for over 13 years. I have always been attracted to living and thinking differently, and was drawn to Buddhist Philosophies and practices from India as a child. I studied ballet for years, and I took my first Vinyasa Yoga class at Dhyana Yoga in 2004. From that point on I knew I had found something special, and immersed myself more fully into the philosophy and practice of yoga asana. I completed my first 200 Hour Training in Vinyasa Yoga at Dhyana Yoga in 2006, and a second 200 Hour refresher in 2014. Throughout the years my personal practice evolved into the practice of Ashtanga Yoga. I am proud to have a daily Mysore practice that continually evolves with all of life’s changes, and I am a student of Caroline Holt Casey in Mt Airy. In 2016 I completed 40 hours of Ashtanga Yoga Training with David Swenson, and 36 hours of training in Yin Yoga with Corina Benner in 2017.
I spent my twenties traveling the world with the newfound confidence I found in myself through my practice. I lived abroad in New Zealand and Thailand where I trained 100 Hours in Thai Yoga Massage at Wat Po, Bangkok and the Sunshine School in Chiang Mai, I traveled all over Asia, including India and Nepal many times to continue my studies in yoga and Buddhism, dabbled in learning Tibetan language and lived in a Tibetan Buddhist Nunnery for a time. I also worked and lived at Tushita FPMT Retreat Center in McLeod Ganj, current home of the exiled His Holiness Dalai Lama, where I was fortunate enough to attend multiple teachings by HH Dalai Lama, Lama Zopa Rinpoche, and Ling Rinpoche among others. Lastly, I finally traveled to the home of Ashtanga Yoga in Mysore, India to study with Saraswathi Jois, the daughter of the late Sri K Pattabhi Jois.
You can expect a creative flow with an Ashtanga backbone in my Vinyasa classes, with options to make the poses accessible to all levels and bodies. I am excited to be expecting my first child in May 2018. I am looking forward to furthering my studies of yoga with Saraswathi in Mysore, and continuing studies and travels abroad with my family.

Monika Brass

Yin, Meditation & Mindfulness

Monika specializes in Yin Yoga. Having lived in a Tibetan Buddhist Community in the hills of California for three years, she brings years of meditation practice that you can feel in the class.

Elizabeth Sitzler

Mysore Director

Elizabeth is a devout student, practitioner and teacher of Ashtanga Yoga. Her main teachers are Jörgen Christiansson and Sharath Jois.

While she was studying history and political science, applying to law school, and competing as a Division 1 tennis player, her father persuaded her to try yoga for the first time; thinking it might help her manage stress. The dynamism of the practice instantly drew her in and she quickly fell in love with the beauty of linking movement, breath, and mindfulness. Soon enough, she was practicing yoga every day; experiencing positive transformations in mind, body, and spirit.

As she delved deeper in the practice she discovered Sri K Pattabhi Jois’ Ashtanga Yoga, the Ashtanga Yoga School of Philadelphia, and her first teacher: David Garrigues. The integrity and structure of the Ashtanga Yoga system was a perfect and natural fit for her. Elizabeth taught at and helped run David's School, AYS Philadelphia, from 2013-2017. Elizabeth is always a student, striving to learn more about her self, the practice, and how she can guide others through their own journey

Carey Paris

Prana Das Instructor

Carey started practicing yoga in 2001. In 2014, after years of an inconsistent practice, she made a promise to herself to get on the mat everyday. Since experiencing the benefits and beauty of a regular practice she decided to pursue a long time goal of becoming a yoga teacher. Carey completed her 200 hour yoga teacher training at Prana House in 2016. She hopes to inspire her students as much as her teachers have inspired her.

Molly Petersen

Prana Das Instructor

After an ankle injury that prevented Molly from her normal workout routine, Molly rediscovered yoga after college and immediately fell in love. Coming from a dance background in jazz, ballet, tap, hip-hop, and modern, Molly felt deeply connected to the breath, flow, and movements of vinyasa and was inspired to pursue her 200 hour yoga teacher training. After completing her 200 hour training, Molly then received her Meditation Teacher Certification in June 2016. In the summer of 2016, Molly began coming to Prana House Yoga regularly and was deeply drawn into the Ashtanga practice. Molly started practicing the primary series of Ashtanga and began to embark on a more spiritual and meditative path. She is in the process of completing her 300 hour yoga teacher certification with Mary Flinn at Prana and will be a certified 500 hour yoga teacher in June of 2017. Yoga has found Molly at the most crucial points in her life and has saved her from stress, anxiety, and toxic relationships. In her classes she focuses strongly on the breath and incorporating that through present moment awareness and mindful movements that we all need to practice on and off our mats.

Anne-Marie Gutierrez

Prana Das Instructor

Anne-Marie takes great interest in the pursuit of yoga and has, over many years, slowly and concisely developed a deep understanding of the personal, social and spiritual benefits of a devoted practice. Initially starting in her teens, Anne-Marie’s practice only became consistent after returning from years of traveling. Coping with a change in lifestyle and the distance from good friends was made possible by a dedication to connecting to her body, breath and mind. That feeling of utmost connection kept her yoga practice regular and flowed into her daily life, allowing for more peace and happiness. Anne-Marie traveled to India in February 2014 under a scholarship which she received to attend the Ajarya School of Yoga in Rishikesh, where she fully delved into the world of Ashtanga, becoming an instructor. The acrobatic, energetic nature of the practice excited her and helped her achieve new goals. This same excitement continues today with her passing on that knowledge.

Ashley Hollander

Prana Das Instructor

Ashley grew up with strong values in being an advocate for her own health and well-being. So when faced with overcoming a stress and anxiety induced auto-immune disorder, initially, she looked to embrace yoga’s calming elements into her taxing lifestyle. She added the physical practice as a complimentary workout to her regular fitness routine and quickly became deeply connected to the mind-body experience. Not only did she feel the benefits of the practice, connecting breathe and movement, on and off the mat, but she instinctively wanted to teach and share the healing powers of the practice. After a year of practicing, Ashley began her yoga teacher training and finished her 200 RYS certification at Prana Das Yoga in September 2017. She is incredible grateful for the experience during this training where she not only felt a positive transformation in living with intention and calmness but also an empowerment to bring these healing elements to others. With great enthusiasm and newfound knowledge Ashley is honored to start teaching and guiding students to find their own happiness and freedom.

Aleta Rogers

Prana Das Instructor

Aleta found yoga in January 2013 after ACL reconstruction surgery. Yoga helped her knee to recover and she soon began to love the practice and its many benefits. She worked as an energy exchanger at Dhyana yoga for three years and that's where she met Derek and Nadia. They both were pivotal in helping her develop both on and off that mat. In September 2015 she began teacher training under their guidance. She finished her 200 hour RYS certification at Prana House in February 2016. Taking her newfound knowledge with her, started teaching a month later. She loves helping students to advance their practice, introducing yoga to people who are afraid to try it, and making yoga accessible to everyone even those recovering from injuries.

Jen Janesh

Prana Das Instructor

Jen’s Yoga journey began with curiosity; she was seeking to try something new in the realm of the physical, something that was more than just another mundane gym workout, that was more like play rather than work. Yoga quickly became the answer. In 2008, Jen’s yoga journey began at a Bikram Yoga studio in Columbia, MD and her curiosity led her quickly to Charm City Yoga (now YogaWorks) in Baltimore where she eventually completed her 200-hour teacher training under Kim Manfredi in 2011. Jen is passionate about teaching vinyasa style classes, heavily influenced by the Ashtanga Yoga tradition.

Beyond the mat, Jen has a driving passion for holistic wellness as it relates to whole body, mind and spirit. She has been studying and engaged in holistic healing for over 10 years and is continually learning and practicing- a perpetual student! She gains inspiration from all the wonderful people surrounding her and passionate about teaching yoga as a way to heal and come to life.

Jen moved to the Philadelphia area from Baltimore in 2016 with her husband, Andrew, and their two children, Marley and Xavier. Jen currently manages the Wellness Department at MOM’s Organic Market. She enjoys many other forms of physical activity (surfing, rock climbing, hiking, running, biking), playing with her friends and family, spending time outside, cooking & eating nourishing food, traveling, and getting crafty.
