I live and train in Cincinnati there’s a lot of great trainers here for a variety of price points and show levels.
David Beisel and his assistant Allie do a great job. David is on the road with his circuit riders most of the time, he’s home more now thanks to WEC but Allison is the home based trainer who runs the home program and takes students to all the shows within the greater Cincinnati area.
New Hope is one of the best if you can afford it and that’s the barn lifestyle you’re looking for. Incredible horses, incredibly expensive. I have a friend that showed with them a few times, you better have $$ to train with them (I think a week at a KY horse show ran her $4000+ not including her show bill). They are on the circuit, winter at WEF, all the major finals etc. They are a very serious AA top level show barn and are priced accordingly with similar expectations for the horses they work with.
I am unfamiliar with Hathaway Hill they must be very new.
Jordina Thorp is new to the area with Maple Wood Equestrian and she’s very good. I tried a horse with her and all her horses were fat and shiny and happy. Her riders seem to do well at shows.
Aubrey Hunt-Sears with Milestone Farm does a good job with hunters and I know some other adults that ride there that really enjoy her.
Karen Reid is another good choice.
I board at Apple Creek with Brigette Myers and she does a great job being budget friendly and has a very family friendly no-drama atmosphere with a large contingency of young professional boarders. We are full right now with a wait list but I can’t speak to what that list looks like, you’d have to speak to Brigette.
It depends on what kind of barn lifestyle you’re looking for. I’ve been riding in the Cincinnati horse scene since 2011, message me and we can talk about the area, shows, different barns, price points etc.
