EGTI Inc., Dale Jeffrey, Principal

Principal & Head School Master

Dale Jeffrey            

Dale has been in the equine gnathology business for over 39 years.  He was the original founder of the IAEDT, Horse Dentistry and Bitting Journal and the Academy of Equine Dentistry.  Although no longer affiliated with the Academy of Equine Dentistry he is proud of the fact that he has had something to do with the training of hundreds of the successful practitioners of today.  Dale and his brother Lloyd own and operate World Wide Equine Inc., a company building over 300 quality equine dental instruments that are shipped to over 60 countries.  Dale always wanted to help horses and found his niche as a practitioner, author, teacher and mentor. 

 He is well traveled and has worked and lectured in many countries.  He is the author of many published gnathological articles and seven books on equine gnathology (dentistry).  One of his latest texts, over five years in production, “Oral Health in Equidae” is EGTI's course text book covering fundamental equine gnathology.   It is the text used by EGTI and several other popular equine dental schools.  He is also the author of the "Advanced Equine Dental Guide" used in EGTI's advanced classes. His primary goal is to help horses and the people who care for them by teaching the least abusive time tested gnathological methods.
