Support groups on campus? Specifically for someone who’s suffered a concussion

I’m trying to help find resources for a student who’s recovering from an MTBI and generally deals with mental health struggles. The therapy they’re getting atm isn’t really sufficient due to it’s infrequency and I figured there would be group sessions on campus that they could join. If anyone knows of resources that pertain to their situation and could share them on here it’d be really helpful, thank you! :)
