Pros
There are a lot of protocols in place that help behavior interns and early career BCBAs in learning skills that will make them better clinicians. They give good feedback and provide opportunities for growth (with some parameters). Depending on the location, the directors can be really supportive and will do their best!
Cons
There is not much support, at all, for people who are further in their career or are experiencing life changes. For being a company lead by a woman and where the majority of company leadership is women, they do not do much to support women or the families of their staff. They also demonstrate extreme favoritism towards anyone who works their way up in the company. If you come in as a BCBA without having worked their as a RBT or intern, you likely aren't going to get the same opportunities.
