FineLine Stables

In our 40 years of history, TRI has always leased a facility to run our programming. We have crisscrossed the Miami Valley and in 2013, landed at a fantastic facility in Springboro – FineLine Stables. For the first time, TRI has access to our own arena meaning we can offer more lessons! Furthermore, this move expands our reach to Cincinnati. With the addition of staff and this large facility, TRI is serving more students than ever before spanning Southwest Ohio!
