Registered Instructor

Adrianne’s love for horses began at an early age. She grew up taking English riding lessons and also enjoyed helping at the barn as often as possible. Just being around the horses has always been a positive and calming experience.  More recently, Adrianne became a volunteer and was amazed at the impact therapeutic riding can have, not only for the riders but for everyone involved.
Joining Simple Changes as an Instructor allows Adrianne to continue learning while sharing her enthusiasm and expertise with others. She is thrilled to have her PATH Intl. certification as a Registered Instructor. In addition to her passion for horses, she brings to Simple Changes a background in fundraising and communications.
