I’ll give you a few trainers from BC. I haven’t ever ridden or had much experience with Albertan trainers, so I can’t recommend any in that regard.
Georgann Gregory has a great rep. An old friend of mine used to ride with her when she was in Southlands, I believe Georgann has since moved to Langley. You could take a peek at her website here.
Justine Annandale of Sperabo Stables trains and teaches out of a place called Imperial Stables in Delta. I haven’t been in the show circuit for awhile, but she seems to have quite a few successful hunter/jumper riders and horses. Click here for her website.
I haven’t seen the new Thunderbird Show Stables facility in person. Their training and boarding facility looks very nice, though, and you’ve got to have heard of the Baliskys. I don’t imagine their services come cheap, but I’d imagine they’d be the people to get in touch with if you’re looking to develop a Big EQ or Big Hunter. Their website is here.
Mark Laskin and Brian Morton of Equimark come to mind, but I don’t know where Brian is training these days or if he’s taking on clients. Lindsay Uyesugi is great with starting youngsters and rides both Hunters and Jumpers. She was training out of her own place, Aquarius Equestrian Centre, but I’ve heard it’s sold and I’m not sure if she’s staying on as a rider or moving elsewhere. I’m sure you could get in touch with either of these two riders, it’d just take a bit more searching to find their current info.
Hope some of this helps!
