Hi Brigitte
Have you come across Intentional Peer Support? It's a really great approach to peer support which fully fits with ACES and trauma-informed approaches. Have a look here and see what you think: http://www.intentionalpeersupport.org/
There's also a great report on trauma-informed peer support for women which you might find really helpful https://www.nasmhpd.org/sites/..._REVISED_10_2012.pdf
Good luck!
Angie
