Inspection Committee

After much discussion, the ATA has changed its approach for inspecting ATA horses to be much more in line with the Trakehner Verband. We have hired Dr Christian Schacht as Breed Director  

Christian Schacht will consult with the ATA as Breed Director. In that capacity, Mr. Schacht will oversee the ATA’s inspection process, and will personally participate in all of the ATA inspections this year.   For those of you that do not know Christian, or did not see his presentation at last year’s annual meeting, he is an internationally recognized trainer, rider, and evaluator of sporthorses.  His family has been breeding and raising Trakehner horses for decades, and he has a deep and abiding love for the breed.    Previously, Christian served as Breeding Director for the ISR/Oldenburg registry.   We believe Christian will be a tremendous asset to the inspection process, and help us improve the standing of the Trakehner breed in North America.    

Please welcome him as one of our own.  

Our Previous Inspection Committee members were:

  • Brad J. Kerbs, Chairman
