Meet Our Instructors 

Amy Coombs (Yoga Teacher E-RYT500) has been teaching Yoga in and around NYC since 2008 at the YogaWorks and Ishta studios, as well as many classes for NYU. Amy empowers students of all ages and all abilities to find the appropriate level of effort. She prioritizes good alignment and a safety first attitude in the physical practice, which makes her classes ideal for beginners, even while Intermediate students are challenged with poses of increasing difficulty. The energetic world of the Chakras is thoroughly explored in her classes. Breath work, philosophy and mindful techniques are interwoven amid the postures, so students leave feeling renewed in both physical and subtle body. Amy believes a Yoga practice not only offers an immediate feeling of well-being, but also provides tools to navigate life’s challenges with grace long after having left the mat.
