Yes, I think, it would. Usually, when other cases are reported any additional case is taken into consideration or so I was told. But, in that case, the perpetrator ( the therapist) would still be investigated on the basis of the evidence from other cases, I think. So, it would not be the OPs case that would decide the outcome. But, it'd still help to report it if there are other complaints. It just gives the board more reason to take the reported violations seriously. If the perp gets punished, who cares how it happens, right? Whether it is the OPs or someone else's case that becomes a decisive factor, the justice would be served then. But I don't know if OP knows of other such cases reported.
