Power Vinyasa Yoga Instructor

Ishmael’s yoga practice prioritizes self-awareness, breath, and reactions. In 2010, he received his Power Vinyasa Yoga certification in Aliso Viejo, CA. His yoga journey began at the end of a long career in Chemical Engineering. He wanted change, and it came unexpectedly in the form of a layoff, bringing confusion, doubt, and fear.

People, events, and life challenges can trigger these reactions, but Ishmael found stability in yoga, where balance came with the learned ability to adapt and remain flexible—both to external situations and changes within himself. Learning how to stay calm and focused in any symbolic storm is why Ishmael shows up on his mat, both to practice and to guide others. His classes integrate poses (asanas), breath work (prana), and intention setting, helping students cultivate resilience on and off the mat.

Ishmael’s favorite pastimes are hiking and spending time with Charlie (Labradoodle) and Max (Retriever). At the end of every trail, he marks the moment with a selfie in a yoga pose. He views life experiences and people like the stones on a hike—some offer temporary support, some fall away, but those that remain become smooth, familiar, and foundational.

Join Ishmael in a Vinyasa Yoga flow, where the lessons learned on the mat become tools for your journey beyond it.

For Toni, yoga is more than just physical practice; it’s a tool for creating safe, transformative spaces for those most marginalized in this industry—especially survivors.

Clare is originally from Wales in the UK, they moved to San Diego age 20yrs old. 

Clare has been practicing yoga since 2015. What started off as “needing to stretch” after fitness classes at the gym evolved into a much needed grounding practice when personal life circumstances took an unexpected turn and became volatile and unstable. Having worked through personal trauma, with yoga at the very center of the work, Clare took their first 200hr YTT at OG yoga, a trauma informed certificate. 

The first classes Clare taught were “under the tree yoga” a free offering for neighbors and friends! Following that, they were encouraged to take another 200hr training through Modo Yoga, leading to a full-time teaching position. Since then Clare has completed multiple continuing education programs to add skill sets in vinyasa flow, sequencing, Pilates, and Yin yoga. 

Clare strives to offer everyone the same gift Yoga gave them - a pathway to self, connection with one’s own body, the autonomy to find choice and confidence on the mat that then leads to those same things in real-life off the mat. An invitation to go within and rediscover individuality, supporting self-love and self-care.

Outside of studio life, Clare loves to do reiki, tarot and astrology based things with friends! They love early morning beach walks, hanging out with plants in their garden, and speaking Welsh to their cat Momo.
