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.

Kimberlin was one of Hidden Hills' early students who has returned to share the love of horses with others who come to the farm.  When she bought her first horse love, Leona, she began to study eventing, centered riding, and natural horsemanship practices with advanced trainers.  Sadly, Leona developed cancer and was laid to rest at Hidden Hills.  Kimberlin now continues to hone her skills on Maggie, an amazing Thoroughbred/Percheron cross. 

Kimberlin finds the relationship between horse and human is the most important aspect of horsemanship in any riding discipline.  She loves groundwork where the relationship often begins and develops  most, and loves helping her students find that rewarding relationship as well. 

With a degree in Music, Kimberlin loves to sing and performs in local theater productions on the side.  She also enjoys softball and hanging out with her Great Dane, Coraline.

Tara Hills


Tara loved horses as long as she can remember, and was lucky enough to have parents that got her a horse, Bagel, 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/youth camp 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.  

You can reach Tara at 423-488-3993 or email her at

Kristen has been around horses for most of her life.  From trail riding to jumping and dressage, Kristen loves anything horses and has always enjoyed sharing her passion with others, especially little kids.

She started working at Hidden Hills at the age of 10 as a volunteer and Tara hasn't been able to get rid of her since.  She threw lots of hay bales and cleaned lots of water tanks as she developed her riding skills, becoming one of Hidden Hills' first Junior Instructors at age 15.  She proved her abilities as she involved herself in as much as possible, helping with pony rides, schooling shows, summer camps, and other farm events.  Now a regular instructor, she continues to refine her teaching style into a fun and educational experience for her young riders.

Kristen's horse Dublin is a tall, dark and handsome Percheron Thoroughbred who puts up with all the crazy events that she drags him to, like Christmas parades and Easter pageants. 

In the rare occasion that Kristen isn't at the farm, which she considers her second home, you will either find her in school or outside on some adventure.  She enjoys backpacking, camping, rock climbing, and spending time her family and friend.  She hopes that one day she will accomplish her dream of becoming a large animal veterinarian--maybe caring for the horses at Hidden Hills!

Meaganne has been riding for over 30 years.  As a youngster, she enjoyed lessons and showing in huntseat and hunter/jumpers.  As she grew, she was a work to ride student, spending every free moment at the farm doing everything from A-Z. 

When she was 13, Meaganne got her first horse, a retired throughbred race horse named Jumanji.  Her next horse was a sweet bay pony named Sudden Impulse, "Impy".  With him she discovered her love of teaching little ones how to ride.

In 2003, she earned her NARHA certification and became an instructor for special needs riders, where she found how incredible horses are for our physical and mental well being.  She enjoyed teaching special needs kids for several years until motherhood merited a break. 

During her "break", she enjoyed teaching Pilates and spin classes.  In 2017, after her 8th child was born, Meaganne began feeling the pull of horses on her heart again, and has joined the Hidden Hills staff.

Megan came to Hidden Hills as a college student in need of place to volunteer to ease her study-burdened brain.   Having worked for 3 summers as a wrangler at a summer camp and with her Certified Horsemanship Association certificate, she proved herself both willing and able to do anything that was asked of her, from farm work to horse work. 

After graduating with her BS in Business Administration, Megan became Hidden Hills' 2018 Summer Camp Director.  She now serves the Farm in a variety of ways, from trail guide and website management to hospitality services and farm organization. 

Megan loves working with horses because you never can tell what you're going to get from them - a whole lot of sweet or a whole lot of sass. Or a mixture of the two that proves how much like people they can be.
