Jak Cooper
Volunteer Peer Support Specialist

Bio

She was born in the United Kingdom and has been living in the US since 2017. In February 2023, she was diagnosed with cirrhosis, then admitted for a Liver Transplant at Stanford Hospital in May 2023. Having experienced the work of the Addiction Medicine team firsthand, she knew that she initially wanted to help make a space for those like her, either pre- or post-transplant, to ask questions without judgement, just as she had with the peer support specialists who supported her on her journey in the hospital. One year post transplant, she joined Stanford’s Peer2Peer program as a Mentor for patients undergoing liver transplants. In Fall 2024, she completed training to gain a Peer Support Specialist certification in the hope of offering volunteer hours to AIM to support others with Substance Use Disorder. She has been sober since her cirrhosis diagnosis and has been active in the sober community since recovering from Transplant.
