Derel Lee Twombly, the creator of Ponies for Parties, had a unique idea in the 1970s that has since become a widely popular service. To save up for college tuition, she began giving riding lessons and occasionally scheduling pony rides for birthday parties. After earning enough money, she was able to focus on her chosen profession, teaching students in the equine disciplines of Dressage and Hunt Seat Equitation. Today, Ponies for Parties has maintained its professional image by providing trained, uniformed pony walkers who lead each pony individually. Additionally, the company has employed horse transport vehicle operators to transport the ponies from dawn to dusk year round, to accommodate the high demand for their services.
