Sherry L. Ackerman is a Professor of Philosophy , as well as an internationally acclaimed dressage clinician. Dr. Ackerman is one of the American dressage industry's leading proponents of dressage as a philosophical, spiritual, and artistic practice and of animal spirituality.

Dr. Ackerman lives at the foot of Mount Shasta, in California, and attempts in the silence of the woods to practice what Dressage in the Fourth Dimension teaches.  Living quietly with her horses and books, she studies, rides and writes, with a keen interest in applying philosophy to lived life.                                                                               

"Dressage in the Fourth Dimension was a groundbreaking publication when it first came out in 1997. It's the first book that addressed the spiritual side of riding, the 'Zen' aspect of dressage as a path to self-realization. The challenges and frustrations that are inevitable even for the most talented rider under the best instruction and with the best schoolmaster horses always present the rider with a choice between honestly facing his own weaknesses and shortcomings and to work on overcoming them or blaming something else and living in a state of denial. Only the first choice leads to enlightenment and true competence in the saddle. It is the  more difficult, but also the more fulfilling path.  Sherry L. Ackerman's book can help the rider find his way
through the pitfalls of ego and frustration to become a more well rounded, more balanced rider and a better human being, who gets more enjoyment out of riding and out of life."  - Thomas Ritter, Ph.D.
