Following years of being active and training, a back injury and the demands of life caused Ron to stray from weight training for a while.  Then he met a personal trainer who showed him how to strengthen his back, glutes, and hamstrings, as well as how to move correctly alleviating his back pain.  With the pain gone and newfound energy, Ron left the corporate world to work in an environment he loves.  His desire is to help others overcome similar challenges and reach their fitness goals.  

Outside of the gym, Ron enjoys coaching youth sports and being with family.

Meghan is a lover of movement, breath, and the powerful peace of awareness.  Originally she wanted to be a Physical Therapist but ended up in the world of Tech & Business.  Yoga became her refuge during a health crisis as a young adult and is still her anchor as she mothers her twin daughters and navigates life.  Meghan is passionate about helping her students honor their body, mind & spirit by connecting to their inner wisdom.  Their wisdom knows when it’s time to rest, challenge or stay steady, but can be hard to hear without consistent practice.

Shagufta Rahmen


Shagufta first came to yoga during college, taking classes as they were available. This basic introduction to yoga was enough for her to pursue a more regular practice and during this time she came across one of her mentors Barbara Rich of Kripalu who taught a very meditative,
breath-focused sequence that resonated deeply with Shagufta. This foundation of breath-work
would become a guiding light for her during a time of loss in her family and helped her begin her journey into a formal training of mind and body. Yoga saved her!

Shagufta completed her 200-hour Yoga Alliance Fluid Yoga certification program under Kevin Gale and his extraordinary team of teachers in May 2016. She loves to share the psychological and physical benefits of Yoga with everyone around her. She has also completed her Yin Yoga Teacher training under the guidance of Anne Dries of Buddha Nest yoga in May of 2018. While her classes are technically in the style of Vinyasa Flow, her Yin approach to
teaching encourages focusing on mindfulness and breath, and she hopes her classes can serve as a restorative time for mind, body, and spirit.


Julie Hanagan 

Yoga, Lifestyle Wellness 

Julie is a registered yoga teacher from the Kripalu Center for Yoga and Health. She received her 200 hour certification in 2020. She is also a Certified Nutrition Health Counselor from the Institute of Integrative Nutrition and Reiki Practitioner. Her yoga journey started later in life when she was experiencing painful arthritis and stress. She consistently attended yoga classes and fell in love with how it made her feel! The balance of class that incorporated postures with centering meditation and breathing techniques allowed her to bring her attention inward. This helped to manage stress while enhancing physical strength, flexibility and well being. Her classes are geared towards beginners or those who have been away from yoga for awhile and could use a refresh. Julie truly believes that yoga is for everyone and it's never too late to begin!

Melissa has been a practicing yogi for over 25 years.  She views the limbs of yoga as her life compass helping her to ground, balance, focus, develop strength and stay true to herself.  She completed her 200-hour yoga teacher training under Cindy Boulter in May of 2019.  She has additionally trained in Yin Yoga under Theresa Murphy and the anatomy of yoga with Susi Hatley. 

Melissa draws on her counseling background to acutely tune into her students and thoughtfully communicate her cues.  Her classes encourage students to link breath with movement, quiet the mind and be present in their practice.  Turning awareness inward allows students to hear the signals their body is sending and move in their own pain-free range of motion.  Through her classes, she hopes to pass on all the joys and gifts that yoga has brought to her life both on and off the mat.

Yoga is about balance to Evelyn. As a mom who loves to backpack, ice, and rock climb, she is always on the go and yoga provides the perfect opportunity to seek out stillness or simply move quietly. She is trained in Yin, Restorative, and Hatha Yoga.

Amy Saunders 


Amy received her 200HR training through Fluid Yoga School in the spring of 2023.  She has been regularly practicing yoga since ~2017.  Amy came to yoga initially to have a physical movement practice, but quickly discovered the mental and spiritual aspects of a yoga practice.  Having a regular yoga practice during the pandemic was especially valuable in dealing with the pandemic and stress from working at Moderna.


Some fun facts, Amy is married to her partner James (10 years in 2024!) and they have been living in Lowell for about 12 years.  They have a rescue lab/shepherd mix dog named Whiskey and a cat named Puck. When she is not on her mat or teaching, Amy loves traveling, hiking, and spending time with family and friends.  Favorite books or ones that had the most personal impact: The Joy of Living: Unlocking the Secret and Science of Happiness by Yongey Mingyur Rinpoche and Lord of the Rings Trilogy by JRR Tolkien.  Current books she is reading: Reality and Wisdom by Lama Migmar Tseten and also some Brian Sanderson novels.

Lelia Leary

Lelia was unprepared to discover the power of yoga when she signed up for a class as a way to add mobility to an exercise regimen. Very quickly she learned that yoga was something extraordinary. She dove into true practice and has never looked back. Her most valuable lesson was cultivating the power of the yogic breath to become more responsive and less reactive.
She’s a mom, a science teacher, and a nature lover. Currently, her passion is training Brazilian jiu-jitsu. She completed her 200-hour training at Revolution Community Yoga. She offers a challenging yet compassionate practice to build strength, flexibility, and balance. All levels are welcome with modifications to ramp up or tone down the offerings. Expect to feel calm, grounded, and restored from the practice.
