My wife and I spent several hours up at Paraiso del Caballo, again, talking with and learning from Angela and Guillermo and getting information striaght from the horses mouth... so to speak.
To answer the OP and with the permission from Angela and Guillermo.
They both have studied and apply the Parelli methods. Angela worked with Monty Roberts, author, in Solvang CA as well as others. (The name means nothing to me as I am still learning.)
They also have studied and use Shiatsu for the horses. I had seen the book in French, open on a table, but wanted to verify their and my understanding before posting.
They do have riding classes and will provide the horse and tack if you do not have. I do not know the charges. We saw lessons with a young lady under 10 years and another being 14 years of age, each at different times and had the full attention of Angela that spent a lot of time and patience on the interaction between the horse and rider. I will also take lessons, Paso Fino riding is different from my long ago cowboy style riding.
They do not have email at their place at this time, so they go to an internet cafe when they can, so emails may not be answered. Phone numbers: 829-216-1006 and 809-507-4013. French, Italian, Spanish and a very little English.
We look forward to a long association while re-learning and having fun.
