German Licensed Dressage Trainer

Jasmin ("Yaz") began riding hunters and jumpers in 1975 and competed in eventing during her college years. After earning a Masters Degree in Environmental Policy and a stint as an environmental consultant (continuing her dressage training as well), she decided to commit herself full time to a dressage career in 2003. Building on contacts in Germany, she established Mane Imports, LLC, focused on finding and importing sales horses for clients in North America, Europe and Japan. Clients included Cesar Parra, Sue Blinks and Karen Pavicic.  

In Summer, 2005, she traveled to Germany to continue her dressage training, rapidly earning her Basispass, Small Bronze and High Bronze medals. She then earned her Trainer's License in September 2006 achieving a grade of "Excellent with Distinction" for dressage teaching. She is currently competing her new horse, Flirt, at Gran Prix.

Jasmin combines her extensive experience with a true love of teaching. She welcomes riders at all levels and is a terrific addition to our training program. Please see Jasmin's website for more information:
