From the time she was a small child, Alexis Ells remembers rescuing injured animals and bringing them home for care.

“Healing has always been innate to me,” says Ells. “It’s been a calling, a passion. I was one of those blessed people who always knew what I wanted to do.”

By continuing to follow this innate passion, Ells is fulfilling her life’s dream as the founder of the Equine Sanctuary, a non-profit organization that rescues, rehabilitates, and re-trains injured performance horses that can no longer compete.

Ells says reaching her dream meant facing life’s inevitable uncertainties and taking action now, not later.

“So many people are waiting for that perfect moment,” she says. But “that right moment never shows up. We have to create that moment. Our destiny isn’t about fate, it’s about a choice.”

Ells’s life has been fraught with great challenges, including a serious illness and a car accident in 1988 that ended her competitive riding career and left her with a serious brain injury. But she believes her success is built on her attitude that being challenged in life is inevitable; being defeated is optional.

“I think it’s about perception and perspective,” she says. “If you give yourself the freedom to know that anything is possible, and you keep having faith, belief, and perseverance despite the odds, you will eventually arrive at the top of the mountain.”
