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.
