As a Peer Recovery Support Specialist at River City Recovery, I bring both professional expertise and lived experience to patient care. My personal recovery journey since 2018 is the profound foundation of my passion for helping others find hope and healing. This work is truly a calling, and supporting individuals walking a path I know personally is one of the most meaningful aspects of my life.
