I highly recommend Jess with Resilient Equine. She worked on several of my lesson horses, and each one has its own body issues and they always ride happier afterward. Notably, my 14.3 Mustang who jumps 3'6" had some knots in her neck, making her less willing to balance herself correctly in turns and she would brace against the bridle. After being worked on by Jess she was markedly improved and much more flexible and willing to accept the riders aids and cues. She is also very very patient with those horses who are unsure about bodywork. She really takes time to get to know the horse and their personality to make it a pleasant experience and get the best results.
Jess has that magic touch that helps horses feel their best and overcome huge amounts of tension in their muscles and joints!
