Hi Gail -- how are you!?! I don't "know" about the resources I'm going to suggest because I don't live in MA. But given that the ARC model for intervention was created in the Boston area, I have to believe there are practicing therapists there somewhere who are using this. I realize there's been upheaval of JRI and the originators, but is there anyway you can access through their information to clinicians. https://arcframework.org/
Also wondering if Adoption Journeys can give you any meaningful help in finding vocational resources/coaching/training. This is a HUGE problem for our developmental trauma population nationwide. ATN has volunteers with young adult children struggling to find meaningful transition services in many states. I've personally been "lucky" that the private transition provider our voc rehab assigned our daughter to (experts in high functioning autism) have been a good match for her and recognized in the first 2 weeks that she, in their words "doesn't really appear to have autism...or there's something else" -- they've been very open to learning about developmental trauma and working with us.
We have a LONG way to go advocacy-wise for the children/young adults who have been the most significantly impacted by their trauma. We at ATN share your concern about the lack of understanding/awareness around addressing attachment issues (dare I say disorders) in addition to the impact of trauma. We advocate for the inclusion of DT in the DSM, and we love networking with/working with our colleagues at ACEs Connection because we agree that knowledge about attachment theory, attachment disorders and attachment-focused parenting are critical components to help heal early childhood trauma. We also advocate for those focusing their missions on building resilience to understand that the most crucial building block for resilience is healthy attachment - which means the most crucial change agents for our children are those parenting them! Equipping and supporting parents is a huge solution to helping this national trauma epidemic!
