Chelsea’s passion for yoga began over a decade ago when she first experienced the benefits of yoga. This initial infatuation inspired her to complete a 200 hr RYT certificate from Soul of Yoga and begin teaching in 2005. Her interest in health and wellness led her to earn a BS in Kinesiology and a 500 Hour RYT certificate from Radiantly Alive in Bali, Indonesia.The journey as a Yoga instructor has allowed Chelsea to teach at a wide range of studios and gyms, host yoga destination retreats, and provide private instruction for students of all ages. Her practice is a blend of Hatha yoga with Anusara principles. Through positive affirmations and breath work, she enables her students to achieve a meditative flow. Chelsea pays special attention to students’ needs through observation as she watches them closely to give insight for adjustments and modifications to promote pain relief and prevent injury.
