Should I contact my mom’s therapist?

My mom wrote me an ‘amends letter’ as per Joshua Coleman (iykyk). It doesn’t seem very sincere, but she included the names and numbers for 2 therapists she saw. She said she also plans to contact Kreed Revere from the Estranged Heart podcast, which I actually listen to as well and find a lot of her advice helpful and balanced.

I’m wondering if it’s a good idea to contact the therapists to ask: how long she’s been in therapy, and what big picture stuff she’s learned. Like if there’s hope for her being accountable in the future. I know she would have to sign a HIPPA form, I’ve done that with my own therapist so she could speak to my husband about my progress.

Has anyone done this? How did it turn out?
