Leah MacClellan, PhD, MSPH, is a facilitator, educator, and guide

whose work explores the relationship between nervous system coherence, sensory intelligence, embodiment, and human potential in a rapidly changing world.

With advanced training in public health and epidemiology, Leah began her career within the Veterans Administration, focusing on rehabilitation research, neuroplasticity, and the body’s capacity to adapt and heal through chronic stress and trauma. This scientific foundation continues to inform her deeply integrative approach to healing and human development.

Through years of personal practice and study in yoga, meditation, breathwork, nervous system regulation, and contemplative traditions, Leah’s approach bridges science, physiology, perception, emotional integration, embodiment, and conscious living.

She is the co-founder of Seaside Power Yoga in Jacksonville Beach, Florida, where she serves as a RYT-500 yoga teacher, educator, and Yoga Alliance Continuing Education Provider. Leah leads yoga teacher trainings, breathwork facilitator trainings, retreats, workshops, and immersive experiences centered around regulation, coherence, emotional integration, sensory intelligence, and embodied leadership.

Leah’s work has expanded internationally through her role as a facilitator and educator with Elemental Rhythm Breathwork, as well as through private coaching, retreats, leadership development, and nervous system-based programming for veterans, first responders, mental health professionals, corporations, and nonprofit organizations focused on resilience, mental health, and human development.

Married for over 25 years and the mother of three, Leah brings both scientific rigor and grounded lived experience to her work, creating intelligent, compassionate, and deeply human spaces for transformation, healing, connection, and expanded awareness.
