I work with individuals and groups using positive psychology approaches and yoga therapy. I also design programs for healthcare facility residents, people with chronic diseases, caregivers, and clinical staff.

Our Clients Say

I enrolled in a series of yoga classes with Stefanie. After several weeks, I became more body-aware, even outside the yoga class. For example, I would notice my shoulders tensing while sitting in traffic, and I could release them, take a deep breath, and feel less stressed out. This positive new habit has stayed with me years later!
