Meet Kelsey

Raised around horses in Carson City, Nevada, I found early on that healing often begins in safe, steady connection. I specialize in trauma, sudden loss, and dissociation, integrating EMDR, Deep Brain Reorienting, experiential play, and equine-assisted therapy to support clients in finding a calm, centered way of being.
