I have completed my level 1 w/ both horses and have started the level 2. I got into Parelli because I bought both my horses as babies and wanted to raise/train them myself. The program does not recommend starting a horse until your level 4 but I chose to back my horses following the program. I am very happy with the results and look forward to learning more.
Although I follow the Parelli Program I also like to learn from other clinicians. I do not think I will ever be able to learn enough about horses. The journey continues!
