Name the actual offering
A public riding lesson at a stable is closer to a community class. Hippotherapy is a clinician-therapy subcategory and needs the therapy evidence stack, including a physician prescription before funding.
Kit should not relabel a trail ride as hippotherapy, or the reverse.
Credentials matter here
Therapeutic riding and hippotherapy have PATH or license facts that a generic stable homepage will not satisfy. Missing credentials stay missing.
One useful answer
If the stable says they work with OPWDD, is that enough?
It is a lead. It is not a route decision and not a substitute for the public offering facts or the clinical documents when those are required.
