Krystal Ingerson

With High Horses Since 2020

Position at High Horses: Instructor and Assistant Facility Manager

Professional Background:

For the past 3 years Krystal has been an Equine Assisted Communications Class Facilitator, Ranch hand, volunteer coordinator and for a short time a basic horseback riding instructor for Horse and Family Institute and Anchored Ranch, Jacksonville, North Carolina. Before that, I mentored troubled kids through Upper Valley Pediatrics and worked as a Dairy Farmhand at Rocky Hill Farm. As a mentor, I was introduced to High Horses and started volunteering in between mentoring and farm chores. Krystal is the daughter of a country Preacher. She loves Jesus and helping her folks at church. has been involved in church youth ministries most of her life.

Hobbies & Interests: Hiking and kayaking, gardening, taking pictures, hanging out with her friends and family, especially her nieces and nephews are a few of her favorite pastimes… and as crazy as it sounds though she likes riding, Krystal loves round penning and lunging far more than riding… learning how horses communicate and learn, learning how that understanding teaches her how to communicate better with horses and even people and then imparting that knowledge in an understandable manner to other people (especially kids), watching them smile with those ah-ha moments is one of her passions. For that reason, my next goal is to improve my riding and train to become a Therapeutic Riding Instructor.

It wasn’t until 2000 when she moved to Putney, Vermont to raise her children that she was able to have her own horses and make them an everyday part of her and her family’s life.  When one of her sons was diagnosed with Asperger’s Syndrome and Sensory Processing Disorder at a young age, the resulting journey led her to Occupational Therapy and eventually to Therapeutic Riding and Hippotherapy.

Sienna Whitney

With High Horses since 2015

Position at High Horses:  PATH Intl’ Registered Level Instructor & Equine Specialist in Mental Health and Learning.

Professional Background: Sienna grew up in San Diego, California where she began volunteering at a therapeutic riding program, B.E.T.H (Bonita Equestrian Therapy for the Handicapped) in the late 80’s. The BETH program was founded and run by JoAnn Rangus who was a passionate, loving and empowering woman and brought out the best in people she came into contact with. Sienna greatly respected and admired her as well as Jo’s lead instructor, Amy Sheets. Over her eight years of volunteering, Sienna learned a great deal about working with horses, people with disabilities, and many life lessons that she carries with her today. She rode and worked at Blackland Farm which was a hunter/jumper stable in Bonita, California.

In the late 90’s Sienna moved to Vermont where she worked for four years for Rozo McLaughlin at Hitching Post Farm, which is a stable that hosts and competes in three-phase eventing. Sienna had the opportunity to work with the at-risk population at an alternative school run by the Clara Martin Center where she worked in the Elementary and Adventure Learning Program. She also had the privilege to work with children at the Barnard Academy. After a dozen years working within the schools, Sienna was drawn back to Therapeutic Riding. She received her Registered Level Certification through High Hopes Instructor Training Course in Old Lyme Connecticut.

Teaching Philosophy: Winston Churchill said, “There is something about the outside of a horse that is good for the inside of a man.” The horse is the greatest teacher, the instructor is only the facilitator and the volunteers are an extension of her. Together with the many other facilitators in our team, each of us has the opportunity to reach our full potential as we partner with our intuitive equine teachers. Sienna is proud to be a part of the process.

Lindsay Harris

With High Horses Since 2019

Position at High Horses: Instructor in training

Professional Background: From the beginning of my memory, I have longed to be near horses, but I grew up a frustrated suburban kid with few opportunities. As soon as I could, I got out west. Somehow, I made my way to a ranch in northern Wyoming, helping care for a herd of 50. I moved on to studying biology at Humboldt State in northern California and worked as a field biologist in Arizona and Alaska, trading chores for lessons and trail rides wherever I could. I finally settled down in Vermont in 2004 working as an aquatic biologist. I also worked and rode at a lesson barn, but it was not enough. I needed a farm! So, I put my biology education to use and figured out how to make a living grazing a herd of organic Guernsey cows. I sold milk, cheese, butter, pastured pork, and beef. I taught dairy processing and small farming classes and advocated on behalf of sustainable farmers in the Vermont legislature and nationally. FINALLY, at the age of 36, I bought my first horse; a fast, intelligent, spicy mustang named Ten Buck Trucker. After many adventures, he is retired, and I no longer milk cows. I still have Trucker and now four other horses, two donkeys, and two equine-loving daughters. For me, the horse and human connection is sacred. Whether they have been in your dreams forever or have more recently found you, their warm smell, the clippity clop of their hooves, their silky soft noses, and of course the miracle of power and speed that they share with us are the most generous of gifts. It is my deep honor to be a part of High Horses and help our two species work together towards healing.

She was a member of the UVM Horse Barn Cooperative for four years, where she served on the executive committee, learning how to run a horse facility and work with a wide variety of horses and people. Olivia has always had a passion for horses and for working with people with disabilities. Therapeutic riding is a way she can bring these two passions together. She began her journey at High Horses in 2019 as a volunteer while shadowing our trainers during her Senior Capstone Project, then came on board as an instructor a year later.
