I'd go to peterson and smith. The treadmill can be highly useful in helping to identify subtle lameness because the horse stays in the same spot and speed is controlled very specifically. So, say the horse doesn't really stride out trotting in hand, that's not a problem because on the treadmill they do each gait at different speeds which can help show where the horse is uncomfortable. What a great advantage to have down there! They also, have a bone scan if you get to that part.
I'd recommend either UF or Peterson and Smith, especially if you are in that general area. I've had good experiences with vets from both, and both have treadmills/advanced imaging capabilities if necessary. Not sure if P&S has an MRI though - I know UF does and they use it when needed/desired for lameness cases.
My pick: either Peterson and Smith or Craig Roberts just outside Gainesville. Dr. Roberts was Chief of Sports Med at Peterson and Smith and is now out on his own.
I will NEVER take any of my horses to UF again. All 3 of my visits there were NOT GOOD. I don't want students trying to diagnose my horse - I want professionals.
Really? A vet school where students do the diagnosing? Thats crazy! All the vet school's Ive taken my horse to they have one or two students, one or two residents and the faculty clinician all look at one patient and bounce ideas back and fourth and challenge each other, ultimately the faculty clinician approves everything. Thats why I think vet schools are the best place to take your horse. Plus you know the faculty clinician is one of the best in the world, you have to be to get that job, and the residents are top class too- getting a residency can be very competitive. Also, since public universities have a smaller caseload than private practices, and often are government subsidized- so you end up paying less because tax payers are covering the cost of the land, buildings etc... you end up paying less. Anyways, thats my big support shpeal for vet schools.
