    RYT200, Level 1 & 2 Reiki Practitioner, Cacao Facilitator

    Website: EricaYoga

      Hi. I'm Erica. I am dedicated to helping individuals who are seeking calmness and peace of mind, helping you find your inner strength through gentle yoga movement, Reiki, and Cacao. I am a 200-hour YTT, Level 1 & 2 Reiki Practitioner, and Cacao Facilitator. Reiki energy and yoga came to me after experiencing multiple losses, trauma, and depression. It has been a way for me to cope with life's challenges and find stillness within. Sharing my knowledge and energy of this with others has been an incredible journey, and I love continuing to share it with others who are open to finding stillness and peace of mind. In my spare time, I love being outdoors and traveling. I like hiking/backpacking, camping, live music, and snow sports. My favorite thing is spending quality time with my Boston Terrier, Oliver. I really enjoy meeting new people and connecting through yoga, Reiki, and a cup of Cacao.

      PT, Certified Yoga & Pilates Instructor

      Website: Rise Together Yoga

        I’ve been dedicated to the healing arts since 1994, when I became a licensed Physical Therapist after earning my degree from The Ohio State University. My early career focused on Orthopedics, Sports Medicine, Home Health, and work in Nursing Homes, giving me a broad foundation in physical rehabilitation and patient care. In 2003, my path began to shift as I discovered the transformative power of Pilates and Yoga. I became certified to teach Pilates through ProHealth and Fitness and began integrating mindful movement into my practice. This journey led me to a 200-hour Hatha Yoga Teacher Training at Bhumi’s Yoga in Strongsville, Ohio, in 2008. In 2005, I opened The Studio on Liberty, a yoga studio in Wooster, Ohio, which I operated until 2019. Throughout that time, I continued to work one-on-one with clients, blending the tools of Physical Therapy, Pilates, and Yoga to support their unique healing journeys. I found this integrated approach to be a powerful way to help people achieve optimal health and well-being.

        Hi, I’m Uli! I’ve always believed in the power of living a vibrant, mindful, and creative life—and I’ve spent the past 30+ years helping others do the same. I began my journey as a medical doctor in Germany, but over time, my passion for holistic wellness led me to become a certified Personal Trainer, Nutritionist, Tai Chi and Martial Arts instructor, and a teacher of Ikebana, the Japanese art of flower arrangement. I’ve taught health and mindfulness classes to adults and seniors, and I’ve loved bringing creativity and calm into the lives of kids through school-based art and mindfulness programs. I’ve been practicing Tai Chi, Karate, and Kobudo since 1993, and I hold a 3rd-degree black belt in Karate. I received instructor and examiner licenses from the German Olympic Sports Confederation and later earned my Tai Chi instructor license in Florida. In 2016, I was honored to receive the Yonkyu Shihan teaching diploma from the Sogetsu School in Tokyo. When COVID hit, I stepped in to help lead the testing and vaccination centers at Montana State University. It was a powerful reminder of how deeply I care about community and well-being. Born in 1967, I’m often mistaken for someone in my mid-forties—and I’ll happily take it as a compliment! I credit it to a life centered around balance, movement, joy, and purpose. My goal is to share that energy with others and help people of all ages feel empowered, strong, and fully alive.

        C-IAYT, ACSM

          I am an ACSM-certified exercise specialist, an IAYT 1000-certified yoga therapist, and a 500-hour RYT yoga teacher. For over 30 years, I’ve taught Functional Strength training and yoga to both groups and individuals. I’m passionate about creating opportunities for transformation and healing through movement and mindfulness. At Strength & Grace, I lead small group yoga therapy workshops focused on strength, balance, and mobility. I also teach Functional Strength for Women Over 40, empowering women to move with confidence and ease as they navigate life’s transitions. I love helping people discover how yoga, strength, and mobility can enhance their lives. My warmth, empathy, and humor are woven into my teaching, and I am deeply committed to blending the insights of Western science with the ancient wisdom of yoga to guide others toward transformation and healing. When I’m not teaching, you’ll likely find me exploring the beautiful trails of Montana or practicing meditation at the Bozeman Dharma Center.

          E-RYT500, C-iRest, LPF-CT

          Website: Turi.Yoga

            I help women cultivate strength, awareness, and grace through embodied movement, breath, meditation, and stillness—with practices that support living well through every season of life. I have lived and worked in the Gallatin Valley for more than 30 years. Since completing my first RYT200 yoga teacher training in 2011, I have continued to explore the intersection of ancient yoga teachings, modern psychology, and neuroscience through ongoing study and practice. My work today draws from yoga, Low Pressure Fitness, iRest Yoga Nidra, meditation, mantra, breathwork, and mindfulness. I offer group classes, private sessions, and, on a limited basis, in-home wellness sessions for women who prefer to practice in a familiar environment. Each session is shaped around the individual, with an emphasis on awareness, strength, mobility, ease, and connection. I opened Strength & Grace Wellness in 2025 as a space for whole-person wellness through movement, meditation, fitness, and mindfulness. I am also fortunate to collaborate with the team at Health in Motion Physical Therapy + Wellness and to teach in a variety of community settings throughout the Gallatin Valley. My training includes 500-hour yoga certification, Low Pressure Fitness, iRest Yoga Nidra, meditation, mantra and Nada Yoga, LoveYourBrain, Warriors at Ease, and holistic health coaching. I am deeply grateful to the many teachers who have shaped my path—and to the Gallatin Valley, the Valley of Flowers, that continues to inspire my work and my life.

            Hi, I’m Alfons. After decades in executive leadership roles at Amazon, Microsoft, BCG, and Montana State University, I made a major shift—to focus fully on my true passion: coaching people toward healthier, more balanced, and more fulfilling lives. Movement and mindfulness have always been at the center of my life. I’ve practiced Tai Chi, Karate, and Kobudo since 1992 and have been teaching martial arts and wellness classes to all ages since 1993. I hold a 4th-degree black belt in Karate and instructor licenses from the German Olympic Sports Confederation, as well as a Tai Chi instructor license from Komatsu-Ha in Florida. I’m also a Certified Personal Trainer and have written and published several books on Tai Chi, balanced living, and leadership. Born in 1966, I’ve never stopped seeking new challenges—whether it's helping someone unlock their potential or learning to rock climb in my late fifties. I love hiking, biking, skiing, and spending time outdoors with my family here in Montana. Whether I’m coaching in the gym, out on a trail, or writing a new book, my mission is the same: to help others grow, feel strong, and enjoy the journey toward lasting wellness.
