SomaYoga is a gentle, therapeutic mind–body practice that supports nervous system balance and whole-body healing with gentle, therapeutic movement. SomaYoga blends somatic movement, breathwork, and some classical yoga to help calm and retrain the limbic system, encouraging a shift out of chronic “fight-or-flight” patterns into a more regulated, parasympathetic state that supports healing. Your 60-minute, one-on-one sessions are personalized to your body and goals and include postural assessment, breath regulation, and gentle somatic practices to reduce tension, ease pain, and improve body awareness. This approach is especially supportive if you’re experiencing chronic stress, inflammation, trauma patterns, or nervous system dysregulation.
