My son started ABA with Keystone while they were still starting up. We had never had ABA before, and learned of them at a SPED meeting with the school district. In the beginning they were absolutely wonderful. They were attentive to my then-10 year-old son (who has ADHD and PTSD), and really showed us a different way to help him be his best. Initially his BCBA was attentive and his RBTs were compassionate yet firm - exactly what he needed. All of that changed the bigger (read more successful) they got. When their center first opened we were heavily pushed to have my son there half of the time. We agreed as we believed greater social interaction would help. It all snowballed from there. The busier they got, the less attention to detail they showed and a steady decline in accountability grew more apparent. What we were being told would happen would not happen. There were numerous times they were unable to have a therapist to work with my son due to scheduling conflicts. Other times they completely forgot to pick him up from school (which they claim they afforded as a luxury to our family but I learned later that they did the same for other families). Per their protocol, a meeting with the BCBA was supposed to happen every month. The majority of the time she ended up cancelling stating that something more important had come up. The BCBA herself offered to help my son in the mornings to get ready for school, then she claimed we were too demanding when we asked for accountability. We were told that my son's team would be limited to 5 RBTs. At the end they pushed it to 7. There were therapists that were most unhelpful with my son and when we mentioned this we were told that we were the problem. At this point they demanded that ALL of my son's sessions were going to be in their center - read out of parental sight/supervision. We adamantly refused as this started sounding very suspicious, and ever so conveniently coincided with their center expansion project. Immediately thereafter, our son's BCBA started telling lies about our son and our family - all of which we could prove otherwise. During a meeting with their President, Todd, he told us that he only cared about his staff, not the children or their families. At that point we fired them. It is a true shame that this organization became what it did. They truly started off wonderfully. I referred other parents that I knew had kids who would benefit from them to Keystone. I was one of their biggest supporters. Now, I wouldn't refer my greatest enemy to them. While their RBTs are mostly wonderful, the administration is to be avoided at all costs. There are many other organizations who offer ABA - some are worth looking in to.
