Rachael’s teaching reflects her personal practice which is guided by curiosity and is always evolving, like everything else in life.
She sees the physical practice of yoga as an opportunity to rediscover and awaken the body through mindful movement so that a greater sense of awareness can emerge. Following the example provided by her mentors, she seeks to serve her students by encouraging them to pay attention to their own experience and respond with intention rather than conditioned habits. Students of all levels are welcome in her classes.
Rachael’s path has been influenced by a network of teachers including Tom Zelle, Hilaire Lockwood, and more recently, Diane Long and Donna Farhi. She’s on the delightful, ever-going journey of adopting an Ayurvedic lifestyle.

Katrina Grendzinski
Katrina is a 500-hour Registered Yoga Teacher (RYT) with advanced training under Hilaire Lockwood through Hilltop Yoga’s 750-hour teacher training program—a lineage rooted in the YogaWorks tradition of Maty Ezraty, blending the precision of alignment-based Iyengar yoga with the dynamic flow of Ashtanga.
Katrina strives to incorporate all eight limbs of yoga in her teaching to offer students not just mindful movement, but a framework for resilience, self-discovery, and embodied freedom. With a passion for yoga’s transformative impact on the nervous system, Katrina creates space for students to integrate past experiences, soften habitual survival responses, and cultivate a lasting sense of safety—both on and off the mat.
Initially, Katrina was drawn to a yoga practice because of its ability to adapt to the highs and lows of being human, while free from judgement or expectation. Since then, it has become an integral part of her healing journey back to a space of authenticity and joy. Now teaching classes as an invitation to quiet fear, reconnect with the body’s wisdom, and step into personal empowerment.

Alaina Streberger
Alaina’s passion for yoga grew from an interest in holistic wellbeing. As a competitive runner, she was led to yoga for the low impact strength and flexibility benefits. As her knowledge of the practice grew, she began to appreciate the profound clarity of the collaboration between breath and movement. She believes the physical practice (asana) is essential to rediscover the innate intelligence of the body and cultivate mental clarity. With a gentle approach and an emphasis on alignment, Alaina encourages her students to tune in and listen to what their body is telling them. She creates an inclusive, welcoming environment for students of all experience levels to explore yoga.
Alaina began teaching in 2017 after completing her RYT200 at Living Waters Yoga in Detroit. She completed her RYT500 in 2025 at Hilltop Yoga Chicago and is also trained in Restorative Yoga. She founded a yoga club in college and led weekly classes to help students with stress management and wellbeing. She enjoys teaching yoga to all ages and ability levels. She uses her training as a Registered Nurse to inform her teaching.

Katerina Popova
Katerina is an RYT500 and trained in prenatal and 1000hrs YT. Katerina still remembers her first encounter with yoga: she was a teenager and a professional tennis player living in Moscow, Russia, who was drawn to something that was considered a strange religious ritual (back in early 2000s). Her mom only agreed to let her take some yoga classes because it would help her be more flexible for tennis but she knew in her heart there was more in it for her. One day, out of the blue, Katerina told her grandpa that she felt yoga would be a major part of her life. Fast forward to today, yoga has been with her ever since. When Katerina stopped playing competitive tennis, yoga was what gave her space to just do what felt right for her body and soul instead of constantly competing and pushing herself beyond her limits. During Katerina’s yoga teacher training with Hilaire Lockwood, yoga became this compass in life to learn about inner and outer worlds. It helped Katerina understand herself and truly trust her inner voice.
Yoga is a journey – one that is never linear but always therapeutic in the end. And it’s a journey that takes place inside yourself. It’s not about making major changes in your life but rather enabling you to find beauty in this imperfect world and your own internal universe. We don’t see the world as it is but as we are.
In Katerina’s classes, you can expect to explore and learn more about yourself through meditation, softening, strengthening, and accepting the present moment in its current form or shape. Never stop exploring your inner and outer worlds! Katerina approaches teaching from a curiosity to explore inner and outer worlds. It’s never a linear approach as yoga practice changes as we change. Expect in her class to learn more about yourself through meditation, softening, strengthening, and accepting the present moment in its current form or shape.
Bailey Zyer
Bailey is a RYT-500 certified teacher, trained under Hilaire Lockwood at Hilltop Yoga. As a former dancer, Bailey once felt apathetic toward yoga, dismissing it as “just stretching.” She was eventually drawn to the practice while searching for a way to manage her ever-present anxiety and the competitive pressures of being a modern young woman—and she hasn’t stepped off her mat since.
Bailey’s personal practice and teaching are inspired by one of her favorite yoga sutras, Sthira Sukham Asanam, which means that a posture should be both steady and comfortable. She approaches yoga as a way to feel at home in your own mind and body, finding a balance between strength and softness—not just physically, but energetically and spiritually as well.
Bailey finds it most empowering—both in teaching and in her own practice—to stay open to trying new things, to play, and to seek the balance between building an inner fire and embracing stillness.editation, softening, strengthening, and accepting the present moment in its current form or shape.
