Meet The Instructors


Mairin Ryan

Mairin was first drawn to yoga for its physical benefits. Not long after  she began to appreciate the mental clarity and calmness she found at  the end of each practice. Wanting to further her practice and share its benefits with others she completed her 200 hour teacher training and is finishing up her 500 hour certification. When Mairin isn’t teaching she enjoys just being a yoga student, especially in any flow or yin style class. She believes that yoga is for everyone and encourages her students to have fun and come to class ready to practice and play.



Anne Grzywa

Anne came to yoga 5 years ago for a stress reducer, but quickly realized yoga’s mind, body, and spirit connection embodied her outlook on life beautifully and became hooked on its philosophy. She spent her college years diving her own practice before getting her 200-hr certification in Costa Rica the summer of 2016 where she studied vinyasa, hatha, and meditation traditions. Her classes are designed to combine breath and movement to create heat and mobility in the body. She believes that if you can breath, you can do yoga. Students of all levels are welcomed to come tune in and sweat it out in her yinyasa flow classes!








Jackie Peters

Jackie has been practicing various styles and teachings of yoga since 2006.  In 2017, craving more knowledge of the yoga practice, she completed her 200-hour certification at Yoga One in Milwaukee.  She has found yoga is filled with physical, mental and emotional benefits that have influenced her life and she looks to help others find these benefits for themselves. Her vinyasa flow classes allow students to build up to a peak pose to receive the greatest benefits of the asana practice by joining breath and movement. She enjoys sharing a thoughtful flow class with students that are new to the practice as well as with those that continue to grow in their practice.







Kat Macdonald

Kat began her yoga journey when she was 12 years old. Her mother signed her up for a preteen yoga class where she first learned the community, and spiritual side of yoga. Since then, yoga was always in the back of her mind. Kat got more serious into her practice in 2013 while she was working full time and going to college in Illinois, as a stress relief. Finally, when Kat moved to Milwaukee she completed her 200 hour yoga teacher training at Core Essence with Shayna and Ali. This training challenged Kat in many ways, including improving her Asana physical practice, as well has deepening her understanding of Pranayama (expanding the breath). Since then Kat has had the opportunity to teach power vinyasa flow, slow-flow, yin, introduction to yoga, and chair yoga for seniors.



Mike Chirchirillo

I was originally drawn to yoga as a way to round out my work-outs during the week to stretch and recover but quickly became captivated by the mind-body connection that yoga can bring to one’s life.  The mental strength and development that yoga offers has been one of the more rewarding aspects and by-products that I wasn’t expecting but is definitely the biggest draw to keep me coming back.  Then I tried Yoga Up…and it was game over for me.  This type of HIIT work out is right up my alley that combines strength training, cardio, core, balance & yoga…it doesn’t get much better than that.  I am currently pursuing my personal trainer certification and incredibly grateful for the opportunity to become a Yoga Up Certified Instructor to help other’s achieve their personal physical and mental health goals that they may have.  I hope to see you all in class!
