Benzo taper provider Massachusetts or southern New Hampshire

My daughter needs to find a new prescriber in Massachusetts or southern New Hampshire for her Valium taper.  She just found out today that her therapist is leaving to start her own private practice.  This therapist has really connected with my daughter so they have already made plans so she can stay with her.  However the therapists will no longer be affiliated with a prescriber.  Can anyone recommend someone?

I've read members say that nurse practitioners can be helpful if you can't find a doctor.  This organization attempts to keep a list of cooperative doctors.  https://www.benzoinfo.com/doctors/
