Thacher’s program is very different from the ones mentioned above.
@GMC2918 indeed- especially for 9th graders, Thacher’s program seems to be more a key component of the school rather than a sports team, which is really cool
Thacher’s (amazing) program is part of their overall curriculum, and is not necessarily geared to experienced riders. My rough guess is that the majority of new freshmen at Thacher arrive with little to no experience with horses. So if you’re looking for a traditional equestrian program, Thacher isn’t quite right.
Understood, thanks @GMC2918
On the other hand, Grier’s varsity riding members make a very tight and strong community, often eating and spending free time together, and many of them take riding all the way to professional and college programs.
It has over 40 horses and many students bring their own horses too. It also has two indoor rings and two outdoor rings, which are all very well maintained. Considering it’s small size (300+ students total), one can see the focus that the school is putting on its riding program.
Sounds fantastic, thanks for the info @SculptorDad
I went to Fountain Valley for my junior and senior. Back then we had an actual working ranch on campus. They recently built a new riding ring and have both western and english programs. Definitely a different school that your traditional NE Prep School - (I did the all boys coat and tie thing for two years before transferring). I enjoyed my time there.
Thanks for the input! @RedSoxFan18 I checked it out and it seems like a very nice program
Check Hotchkiss - they might.
@sunnyschool unfortunately, they haven’t got one
FWIW- If you really love a school without a barn or riding program on campus, I wouldn’t write them off right away. There are many show barns in NE and beyond that may be in close proximity to a boarding school and there may be other students who have the school’s blessing to ride/ or board their horse off campus… instead of participating in another sport. Sometimes… they’ll only allow one season/term but I’ve seen allowances made when an athlete is exceptional.
It never hurts to inquire so I would recommend calling the AO to see if they have an off-campus program with a local barn/trainer. In this day and age there’s actually a good chance they do… especially if the school is located in horse country- which many are.
I rode at BS and when I switched schools from an on campus show/ eventing barn to a school that didn’t have a program. I brought my horse with me and commuted to a barn down the road after class. The school was very accommodating and it worked out really well. At that time, there were three other girls ( fellow refugees from all-girl schools 
) who did the same thing and it was great because between the three of us we were cleaning up on the weekends and the school started announcing our results with the all the other " school sanctioned " sports during morning meetings.
Some schools don’t have a boathouse or a robust crew program but they do have students who go off campus to race/train with a local rowing club. Always good to ask first before you write off a school you may love. 
Besides- I’m not big on choosing a school for a sport. If there’s a will… there’s a way : A great thread on the topic http://talk.collegeconfidential.com/prep-school-parents/1564851-choosing-a-bs-because-of-a-sport-%C2%97-pro-con-p1.html
All the best and good luck!
Great advice from @PhotographerMom – and the horse she rode in on. 
LOL @ChoatieMom … and fell off of multiple times.
Head meet 5ft Oxer … or let’s crash into some godforsaken " Water Feature " after a 4ft drop… Good times! I wish I was still that fearless… or stupid. Take your pick! Now that I’m an old woman, I feel every single fall when it rains.
I remember a crew coach from the early days informing me how expensive rowing is… and I then looked at him dead in the eye and said, You can’t scare me. I rode horses. Famous last words… Okay- Twelve years later… Uncle!! LOL. How about badminton, kids?
Haha, thanks for the advice! @PhotographerMom I’ll def look into off-campus riding options
My horse went to the Putney School as a school horse when I went off to a non-riding school. They do compete but not sure at what level etc. and you definitely can bring your own horse.
Thanks for letting me know! @chemmchimney
