Meet our instructors

Our instructors are not only horse professionals, but they are interested in the overall well-being of both our horses and our students, treating both with respect and care.   They are interested in helping our riders develop a true love and respect for the horse and horsemanship, understanding the horse's needs while learning leadership skills that apply to both horsemanship and to life.  

sara kreps

Although she never had horses of her own, nor any consistent opportunities to ride, Sara Kreps fell in love with horses in the fifth grade and never outgrew them, much to her parents' chagrin. After high school and a six year stint in the U.S. Navy as a linguist, she pursued her childhood dream and went to study horses at Meredith Manor International Equestrian Centre in West Virginia, receiving her Riding Master VI certificate as well as her Level I Instructor's qualification.  

Sara is California born and bred, but transplanted to Tennessee in 2006 to share her love of horses at Hidden Hills.  Aside from horses, she loves to cave, swim, SCUBA dive, ski (just about anything with water), read, write, travel, sleep, etc.  As you can tell, her interests are varied and she tries to stay active.  

The two things that haven't changed is her love for Christ, Who has so far kept her more or less safe in all her endeavors, and her love for horses, who have, at times, challenged that safety.  But in her opinion, that just makes things more fun!

Tara Hills

Tara loved horses as long as she can remember, and was lucky enough to have parents that got her a horse when she was 12.  She learned all the basics on that horse, from horsemanship to life, proudly calling herself a "backyard horse girl."  In college, she earned her Certified Horsemanship Association certification and taught horsemanship at a summer camp in South Carolina.  After college, she managed the stables and horse program at a resort in North Georgia for several years.  

In 2003, it was a dream come true to return home to the Chastain Farm and begin her own horse farm, Hidden Hills Farm, on the property.  Bagel was her first lesson horse.  

It brings her great pleasure to share the love of horses with others, helping others learn to feel, ride, and live the rhythm of horses.
