GHY Owner
Jennifer Witt
Chicago shaped my hustle; Wisconsin taught me how to breathe. After a decade in the fast-paced city, I moved to Milwaukee in 2010 and instantly fell in love with its grounded, easygoing rhythm. My career in Mutual Fund Administration and Compliance at U.S. Bank and my family keep me very busy, but yoga is where I reconnect with myself.
Movement has always been part of my life — especially gymnastics — but HOT power yoga lit a fire in me I didn’t expect. The heat, the challenge, the playfulness… I was hooked. That passion grew into a dream: creating a space where others could experience the same transformation.
Opening Tosa’s first HOT yoga studio has been one of the greatest honors of my life. GHY’s instructors have shaped what it has become today. Every day, I’m inspired by the strength, growth, and spirit of our community.
See you on the mat. Namaste.
Your Instructors
Ellen Joppe
RYT 200. I am a retired division one athlete and I started my yoga journey in college when my teammates would take yoga classes in between soccer practices. While having a competitive mindset, I started to increase my yoga practice and I strictly saw it as a posture-based activity. After college, I started to explore the practice of yoga even further. I realized that there was so much more involved in yoga than just the posture. As I grew deeper into my practice, I found internal happiness, mental clarity, and personal growth. I continue to step on my mat as an outlet to relieve stress and as a source of therapy. I completed my 200 hour certification under Jessica and Al Noche from Kramas Yoga in Madison. I hope to inspire other yogis to find personal happiness and growth, and become the best version of themselves!
Chandler Nies
Chandler brings her love of movement, music, and creativity into every class she teaches. As a certified yoga, yoga sculpt, and contemporary mat Pilates instructor, her classes blend strength, mobility, creativity, and connection in a way that feels equal parts empowering, grounding, and freeing.
She’s passionate about fostering community and creating an approachable space that takes the pressure and perfection out of yoga and movement. Expect creative sequences, intentional flows, upbeat music, and modern flares that make class feel fresh, challenging, and genuinely fun. Chandler encourages students to explore their edges, stay present, and connect with themselves and the people around them—leaving class feeling strong, energized, and centered.
Hailey Herro
Twenty years ago, a running injury forced me onto a yoga mat, and it was the best thing that ever happened to me. It was the only movement I could do while healing, and it completely transformed how I connect with my body and mind. Now, with 9 years of teaching under my belt as a 500-hour RYT, I am here to help you find your own balance of calm and strength. My classes are warm, inclusive, and fun, always designed to leave you feeling stronger and more grounded. Because I love movement, I am also certified in Barre, personal training, and nutrition. When I’m not teaching, I’m usually training for my next marathon, cuddling my animals, or exploring the local food scene for the next best restaurant!
Caitlin Moyer
Caitlin has always been passionate about sports, health and fitness. She grew up playing golf and is an avid runner, completing four marathons and several half-marathons over the past decade. After spending 18 years working for the Milwaukee Brewers, Caitlin started her own communications and marketing business and also chose to make fitness a priority. She completed her 200-hr yoga teacher training in Nosara, Costa Rica and went on to pursue her Level 1 and 2 Yoga for Golfers certifications. She currently trains the Marquette University Men’s Golf Team on a weekly basis. Caitlin is also a NASM certified personal trainer with a golf fitness specialization. Her classes focus on functional movement, designed to increase strength, flexibility, mobility and balance while enhancing recovery and mental focus.
Katherine Etta
Katherine, RYT-200, began practicing yoga regularly after moving to Wauwatosa for her career in mid-2023 and discovering Get Hot Yoga. Before her move to Tosa, yoga had been a part of her life off and on, but not consistently like it is now. Katherine specifically loves the presence and strength she feels both on and off the mat as a result of the practice. She completed a 200 hour teacher training program through Healium Hot Yoga in Bay View - Milwaukee in June 2026 and loves being able to share her passion for movement through her creatively designed classes. Katherine's teaching style is playful and supportive. She loves putting together a good playlist to pair with her flows!
Off the mat, Katherine enjoys adventuring around Milwaukee with her corgi (Ollie), reading, journaling, traveling, and enjoying iced coffee year-round regardless of the weather.
Susan Keefe
I have always been passionate about health and wellness and instantly fell in love with yoga since day one. I began practicing yoga in 2013 as a step toward self-love. With only the intention to deepen my practice, I enrolled in the 200-hour yoga teacher training through Satya Life School of Yoga in September 2019. I soon realized I wanted to share the healing power of yoga and the mind-body connection to others. In addition to teaching at Get Hot Yoga, I am currently working on my 500-hour teacher training through Yoga Renew.
Personally, yoga is about the balance between strength and flexibility, focus and breath. My classes combine strength and mobility work in a dynamic, challenging vinyasa flow style. I love it when the gifts we have learned on the mat are taken and incorporated outside of the studio and into our lives.
I am endlessly grateful to all of the teachers who have guided me to a better understanding of yoga, and I am honored to share this gift of knowledge with others. I will always be a student of the practice and am deeply grateful for the loving wisdom my teachers have shared with me.
When not on the mat, I am traveling or working as a licensed esthetician of 16 years and own a day spa in Brookfield.
Kim Peterson
An educator by trade, Kimberly (RYT 200) discovered yoga as a form of self-care in 2013. Through yoga, Kim has become stronger mentally, physically, and emotionally. She loves to share the gift of yoga with underserved communities as Kim wholeheartedly believes that yoga truly is for everybody!
Abbey Graffagna
RYT-200. Abbey's classes are known for strong, well-paced sequencing that builds heat and momentum while still honoring the foundational principles of the practice. Students can expect a faster-paced, more athletic flow designed to build strength and stamina, paired with the attentiveness and adaptability needed to support practitioners at every level.
Abbey approaches each class with the same commitment: to create a space where students can move with intention, breathe with purpose, and leave feeling stronger than when they arrived.
Sofia Ismali
My yoga journey began in 2008 and deepened in 2015 when I discovered the dynamic practice of power vinyasa. What started as curiosity became a meaningful part of my life—a space to build strength, cultivate resilience, and reconnect with my body and breath. After completing my yoga teacher training, I began teaching immediately with a passion for creating classes that inspire strength, balance, presence, and self-discovery. I believe each time we step onto the mat is an opportunity to explore, grow, and connect—both with ourselves and with one another. My teaching blends mindful movement, breath, strength, and intention, creating space for students to challenge themselves while honoring where they are. Off the mat, you can find me spending time outdoors, traveling, eating my way through new cities, and making memories with the people I love.
I hope to see you on your mat soon.
