Mackenzie Parks

Owner and Head Instructor

Mackenzie learned to ride with Nancy and Twin Oaks from a young age, and returned after college to teach lessons and camps at Twin Oaks. In April 2015, she acquired the business from Nancy and has continued to provide quality lessons and camps and taking excellent care for the Twin Oaks horses.

Mackenzie continually improves upon her riding skills and adds to her equestrian experience by actively competing and training with talented trainers Holly Wilmoth and Paul Ebersole with her horse Moe. Her experience includes:

  • 10+ years teaching experience with children, teenagers, and adults
  • Currently showing in Eventing at Training/Preliminary level
  • Certification and experience working with children on the autism spectrum
  • BS degree in Psychology from Brigham Young University

Mackenzie concentrates on teaching correct equitation and proper horsemanship to all her riders to create a well rounded equestrian education.

Katie Lorenzen


Katie became enchanted with horses with her first lesson in Upstate New York at age 5. Much of her early experience was with Pony Club, and she has achieved her C3 rating and competed at Pony Club Championships. She discovered what a joy it is to teach others and build confidence with beginner riders! Katie has competed up to the CCI* level in Eventing and is now bringing up her young off-track Thoroughbred "Risk It" as an Eventing prospect. In addition to her equestrian endeavors, Katie is working towards a degree in Veterinary Medicine.

Susan VonHoene


Susan began riding at a young age and has been riding and working at Twin Oaks for over 10 years. She is an integral part of our Summer Camp program and serves as the head camp instructor. Susan is also a dog trainer with Sit Means Sit Training!

Our Equine Staff


I am a Pony of the Americas who is 18 years old and 13 hands tall. Check out my awesome color pattern, especially on my backside! I have been a lesson horse before and a great teacher for beginner riders. My talents include finding food, teaching riders to be assertive, and keeping my stall tidy.


I am a Connemara cross, 10 years old, and am really friendly. I like to whinny "hi" to horses when they walk by my stall. I love jumping, and have a lot of fun with my riders! I love my friend Peaches.


I'm a dark bay pony that's about 13 hands tall. I am great with beginners and riders learning to canter and jump. I'm a little shy, but everyone says I'm so cute!


I'm a Connemara and everyone says I'm really cute. I'm 15.1 hands and have a nice, thick tail. I'm pretty easy going and friendly! When I get bored I paw at the ground to get your attention.


I'm a 15.2 hand Thoroughbred, and I love to jump! Before I came to Twin Oaks, I competed extensively on the A/AA Hunter circuit. Now I am enjoying a quieter kind of life with the lesson students here. I am mostly ridden by the more advanced students, but I'm very sweet and love visitors.


I'm about 15 years old and an Appendix Horse. I'm a fleabitten gray. I am great with riders who are learning to jump. I have a nice canter and like my new life here! I came to Twin Oaks in December 2017.


I am a tall Bay Thoroughbred with really nice gaits. I am great for learning to jump and I take care of my riders. Let's be friends!


I'm a cute POA pony, like Appy, but I'm a leopard Appaloosa. I have fancy gaits and even though I'm small, I jump really well! Come meet me in my stall and tell me I'm pretty.


I'm a chestnut Morgan/Quarter Horse gelding. I am really friendly and laid back! I'm very social and like to be with my friends. I have smooth gaits and riders feel very comfortable on me, and I love being here!


I am an off-track Thoroughbred who raced until I was 7. Even though I raced a lot, I'm super calm and love my new job! I am ridden by more experienced riders and like going on trail rides, jumping, and going cross country.


I'm a Thoroughbred/Cleveland Bay and have lived at Dancing Horse for a long time. I'm a pretty bay color with no markings. I'm the tallest horse at Twin Oaks, standing at 16.2 hands. I have a nice slow trot and steady canter and take care of my riders.


I have been a lesson horse for many years and am now enjoying my retirement with new friends and a nice big field in Purcellville! I am 30 years old and super sweet.
