Kate Vasquez
Executive Director & Founder

Most people take years, or even a lifetime, trying to figure out what makes them happy.  This is not so for Kate Vasquez.  As an Autistic individual herself, she’s known since early on that she wanted to combine her love of horses with her desire to help others like her with special needs. As early as elementary school Kate enjoyed assisting with activities in the special education department rather than enjoying recess with her classmates.  About that time she attended a summer bible school camp where she especially liked the horseback riding activities.  Kate had found her niche — horses and helping those with special needs.

Even at that tender age, Kate had a dream, and she set out to make it a reality.  She volunteered at a Therapeutic Riding Center in TX.  A valuable asset to the program, she was put on the fast track for her certification as a therapeutic riding instructor for adults and children with special needs, which she achieved soon after her high school graduation.

Majoring in psychology and minoring in special education, Kate then attended Texas A&M University San Antonio full time, but never gave up her duties at the Therapeutic Riding Center.  She taught a full load of classes there and also took time to attend and take classes at PATH international’s (Professional Association of Therapeutic Horsemanship) conferences throughout each year.

With PATH she first became a registered therapeutic riding instructor, then a certified equine specialist in mental health and learning instructor.  She was allowed into the latter program early, due to many letters of recommendation extolling her maturity and dedication to those with special needs and horses.

Towards the end of her college career it was time for Kate to continue chasing her dream, so she found and started Open T.R.A.I.L. (Therapeutic Riding Actively Improving Lives) Ranch, her own therapeutic riding center.  She owns majority of all of the horses and has specifically trained them to be used in her program for therapy.

Graduating Summa Cum Laude in 2012, the ever over-achieving young lady continued accruing academic accolades.  She also minored in Sign Language, and has completed and received her certification for her equine therapeutic vaulting instructor’s license.  Both specialties aid Kate in helping different types of children and adults with special needs.  She also is a registered Mentor for PATH International, able to aid those wanting to go through the same process she did and help them achieve their dream of becoming a therapeutic riding instructor.

Gabrielle (Gaby) Perkins
Occupational Therapist

Gaby’s riding career started as a 7 years old in Virginia. Her parents co-bought a small pony, Peanuts, and brought him home in the back of a pick-up truck. Neither family knew much about horses, but that pony was the first of many ponies and horses to come.

She was very active in Pony Club and graduated as an H-A from Difficult Run Pony Club. She rode competitively in eventing up to preliminary level and dressage up to 2nd level. She does not currently own a horse but is still passionate about them.

Gaby graduated from Radford University with a degree in Political Science. Shortly after graduation she discovered therapeutic riding. She attended a certification program at the CHEFF center in Michigan, and became a NARHA certified therapeutic riding instructor. She worked for several years for several small programs in Virginia and became the head instructor at the Rainbow Therapeutic Riding Center.

There she was responsible for scheduling and teaching lessons, training volunteers, and training horses. It was during this time she met an occupational therapist who influenced her to return to school.

Gaby graduated from the University of Puget Sound and became a licensed occupational therapist. She has worked in a variety of settings such as a birth to 3 center, home care, hospital pediatric inpatient and pediatric acute care and private clinics, in Washington, Colorado, Kenya and now, in Texas.

Gaby recently completed her AHA, Inc. Level 1 and Level 2 Hippotherapy Treatment Principles courses and is now a PATH Intl. Registered Therapist. She is very excited to join Open TRAIL Ranch to learn from her patients, horses and volunteers.

When not working as an occupational therapist, Gaby is a wife and a mother of 2 children, Caleb (13) and Amelia (11). Amelia enjoys coming out with her mother to help out in the barn. Gaby and her husband, Rick also compete in triathlons and are proud of their Ironman accomplishments.

Nellie Schmidt

Growing up as the youngest in a large family, Nellie’s love for animals began at a very young age, surrounded by dogs, cats, goats, donkeys, rabbits, chickens, geese and eventually horses. She began riding at 9 years old when her older sister received horseback riding lessons for her birthday, and like your average younger sibling, Nellie tagged along. Throughout middle and high school she participated in many drill teams, including riding for the Tejas Rodeo Rough Riders for 3 years.

Nellie then took her love for horses to Asbury University in Lexington, Kentucky, where she double majored in Equine Studies and Psychology, focusing on Equine Facilitated Mental Health. While in Kentucky, Nellie participated in the school’s Police Mount training program and taught therapeutic riding lessons for class credit. As a lifelong learner, Nellie has dabbled in almost every discipline of the equine field: re-schooling Off-The-Track Thoroughbreds at The Secretariat Center, working with Road to the Horse competitors, Ken McNabb & Stacy Westfall in ranch horse and reining training, leading trail rides at youth summer camps and training extensively in natural horsemanship.

Upon graduation, Nellie moved to NW Houston where she worked as Equine Manager & Trainer at a PATH Intl. Premier Accredited Center, and received her certification as PATH Intl. Therapeutic Riding Instructor (CTRI) in the fall of 2018. Her love for the Hill Country brought her back to San Antonio, and her passion for connecting amazing horses with amazing people brought her to Open T.R.A.I.L Ranch! When not at work, Nellie can be found hitting the trail with her rescue mutt, Cappuccino or playing laser tag with her kitten, Hazel.

Pam McGonagill

Pam McGonagill was born and raised in Texas and is known as a West Texas girl. She grew up riding a mesquite tree horse and pretended to rope her brothers. Her interest in horses grew with a scrapbook titled “Horses I Love” of drawings and pictures. Things change as you grow up and she adventured to numbers which led her to becoming a bookkeeper.

Her experience has many twists and turns which include, working with insurance companies, oil and gas companies, two bankruptcy trustees on business cases to non-profit organizations.

As the bookkeeper at Open T.R.A.I.L. Ranch, it brought back memories of her scrapbook, “Horses I Love”. As Pam readies herself for retirement; she’s looking forward to becoming a volunteer here to fulfill the dream of loving horses and getting misty-eyed watching the OTR participants and the families
beam with joy and pride of changing a life, one ride at a time, including hers as she watches these awesome riders.
