Many times you can find parelli/NH people that aren't neccessarily "starred" or certified or whatever.
That sounds "unprofessional" i guess, but there are a lot of really great people out there in any discipline that have been pursuing horsemanship for decades, and are just as good as "certified trainers." They may become your lifelong friends! And they don't charge nearly as much.
(my NH teacher is also a high school teacher, a single mom of three, and she's in Tyler, Texas right now for the National Drill Championships with our local, non-brand NH stable, Unbridled Spirit) Sorry I'm very very proud of them! :)
But the point is, she's not certified or on any NH-only sites.
However, she's 40 and been riding since she was a teenager! (First English, and now 8 years of NH) So she's a GREAT teacher.
I'd advise you to check out stables in your area for NH trainers that advertise there! Many non-brand offshoots have started all over my area, despite the grumblings of marketing I see on this forum!
Of course, be CAREFUL. If you don't like them, get bad vibes, or don't like their methods, you CAN get out of it. (Don't agree to anything long-term)
There are some oddball trainers out there, in any discipline! Keep your safety and your horse's firmly in mind. You may even find a NH-themed stable that you could take lessons at whenever you saved up enough.
I always love to see people interested in NH. I have found it pretty darn cool (I used to ride amateur amateur amatuer western, and I liked it), but I've read several books, and watched several youtube videos too!
But it's just not the same as having a wise mentor by your side. Because every horse is different.
I hope this helps, and if you have anymore specific NH questions please feel free to privately message and I'll do my best to answer them.
