In brief: Best, most professional training and instruction in the DMV area. The owners live on the property and are completely devoted to the horses. Lots of individual attention and customized care. If you’re at the barn in the late evening… you might notice Jen or Sam coming out to check on the horses, tuck them in, and give them a flake or two of hay for«midnight snack.» The lessons are simply THEBEST. Thoughtful goal-setting… specific feedback and exercises aligned to your goals… and a totally positive, encouraging, yet demanding atmosphere. No matter your level, you WILL become a better rider and you WILL feel better about your riding. Lots of opportunities to compete, but no pressure if you’re not interested. Barns are notorious for drama and craziness… so much so that a certain degree of barn drama comes to seem inevitable. Not so at ACSH. The vibe is professional and friendly. In six months, I have heard zero critical comments about anybody else’s riding or handling or anything else. You’ll get lots of feedback but it will never feel negative. Drawback: The facility is not pretty nor in particularly good repair. The tack room is crowded and poorly lit… but the water buckets are SPOTLESS. It’s all about the priorities, right?(: FWIW: I’ve boarded at four different facilities in the area… ridden at five… and taught at four. ACSH wins the blue ribbon for everything but looks.
