Cornerstones: A Passionate Journey with Leslie Thomas

Nestled in the peaceful countryside of Sherkston, Ontario, Cornerstones is more than just a small farm—it’s a place of transformation, healing, and growth.
Our mission is to create a safe and welcoming environment where individuals can explore their personal journey through equine facilitated learning. Led by Leslie, whose methodology is marked by empathy, inclusivity, and a deep commitment to personal development, Cornerstones offers a unique approach to learning that goes beyond traditional coaching. Her background includes a lifetime with horses, 10 years working with vulnerable populations in homelessness and addictions and eight years as an EFL coach. Leslie's education includes a B.A in Psychology, Social Service Worker Diploma and certifications in EFL practice including The HERD Institute and Equusoma Level 1 - Horse Human Trauma Recovery. Leslie combines theoretical concepts with hands-on experience, inviting participants to engage with horses in ways that foster self-awareness, emotional regulation, and interpersonal connection. Each session is carefully customized to meet the individual’s needs, ensuring that participants not only gain insight into their own behavior but also develop practical tools for navigating life’s challenges.
The horses play a central role in this process, providing non-judgmental feedback, helping individuals identify patterns, break down barriers, and ultimately build stronger, more confident relationships with themselves and others. Participants leave with a greater sense of clarity, empowerment, and emotional resilience—tools that can be applied to both personal and professional life.
At Cornerstones, we believe in the transformative power of horses and the deep, often life-changing connections they help foster. Here, we walk beside you on your journey of growth, one hoofbeat at a time.

Our Herd

Introducing the heart of Cornerstones EFL.

These four horses form the heart and soul of Cornerstones. Each of them has a unique history, skill set and personality. Each brings their own singular talent into relationship building within EFL sessions. Below you will find their biographies.

Star is a Quarterhorse mare who was bred and trained to excel in the western show ring. Following a serious injury while in training at four years, Star was retired to broodmare status. In 2018, at 16, Star officially retired from broodmare to EFL specialist. Star excels at teaching how to set and hold boundaries.

Lily, born in 2000, is a Quarterhorse who was bred and trained to be a western show horse. Lily also retired to broodmare status at a young age before coming to Cornerstones at age 18. Her loving and patient nature gives her the ability to hold space in session, to bear silent witness for us and to teach us that there is value in each of us.

Sophie was born in 2012, most likely in a "PMU" (Pregnant Mare Urine) operation somewhere in Alberta. PMU is used in the manufacture of Premarin, a hormone replacement therapy for women. Sophie was likely about 3 months old when first sold at auction in Alberta before being shipped to Ontario at 9 months where she again went through the auction ring. Sophie joined Cornerstones at 1 year of age. Sophie is a mixed breed with Quarterhorse and draft horse features. Sophie will draw your attention to details.

Maddie is close to 30 years old with a wealth of experience as a rodeo horse. Maddie took her previous owner to the Canadian National Rodeo finals in the "heeler" postion of team roping. Maddie has Cushings disease which impacts her hormone levels. She is nearly fully blind but incredibly skilled at navigating territory around the farm. Maddie teaches us to uncover our own innate sense of resilience and hope.

Mouse, along with her nearly twin sister Machka, found a home here at Cornerstones after being rescued from under a sea container at a local tire shop. They are our resident mousers and snugglers.

Ranger is our 13 year old shepherd mix who came home with me from our hay supplier when I went to pick up hay and "accidentally" picked out this pup from the litter. Ranger is a love bug who will never tire of chasing balls and making toothpicks from sticks on our living room floor!

In Loving Memory...

While no longer with us in the physical world, these souls continue to have a meaningful impact on the work we do.

Omega Red Dog aka Buddy. Buddy joined Leslie at 3 months of age and chose to stay until his 31st year. He was a master of subtle communication, a peacekeeper in the herd and the most authentic relationship Leslie ever experienced. His calm nature offered a peaceful presence for all who interacted with him.

Trigger defied all definition of Border Collie. He had no desire to herd or chase balls. His favourite passtime was visiting the neighbours for treats. This beautiful canine soul spent his 16 years bringing a calming presence and gentle pressure to slow down and smell the roses.

“Horses are incredible teachers of forgiveness, acceptance, and unconditional love.” – Shannon Knapp.

Our horses come from all different backgrounds and each have a unique personality. Each member of the herd contribute to the program in their own way.

They offer healing and compassion. Whether it's through gentle nuzzles, patient listening, or simply standing by in silent solidarity, our horses have an innate ability to connect with people on a profound level.

Together, they form a tapestry of healing and hope, offering countless individuals the chance to experience inner growth and healing. Our clients often leave with a renewed sense of peace, having been touched by the gentle grace and enduring strength of our beloved herd.
