Callie Eisenhart - Osteopathy Associate

Callie Heinle was raised in Pennsylvania, where she acquired her love of horses at a young age due in part to her mother’s role as head trainer at North Arabians. She grew up riding hunters for much of her childhood, then transitioned to reining horses in her teen years. As an adult, Callie strives to further her horsemanship and knowledge by studying under some of the top horsemen in the industry. She regularly travels the National Reining Cow Horse Association (NRCHA) circuit with nationally ranked trainer Trevor Carter.


In 2016, Callie attended Animal Dynamics in Ocala, Florida obtaining a certification in Massage and Electro-Acupressure which led her to apprentice in osteopathy with Dr. Hancock in 2018.

Callie’s other interests include: hiking, camping, and traveling. She is an avid reader who enjoys collecting various equine and history books.

Debbie Romero - Human Bodyworker & Customer Care

Debbie began her career with a National Certification in Therapeutic Massage. In 2005, Debbie added Certification in Orthopedic Massage and maintained a full time private practice specializing in injury and surgical rehabilitation of connective tissue (soft tissue, muscle, tendons, ligaments and fascia). From 2010-2012 Debbie became the lead instructor at the Virginia School of Massage, sharing her extensive knowledge of human anatomy and movement. Seeing a need to help people move pain-free in daily activities, Debbie became a Certified Alexander Technique practitioner in 2014.

How we use ourselves in our daily activities can affect our bodies in a positive or negative way (pain, tension, stress). It is in movement where we need to re-educate people on how to use themselves well to remain pain-free and fit. Debbie is passionate about teaching others how to move with ease.

Debbie lives on an organic farm in Central Virginia with her husband of 40 years where she loves to practice Alexander Technique while riding her horses.
