Hello, I'm Jessica Peterson, an Associate Professional Counselor (APC) at Thriveworks in Cumming, GA, supervised by Hannah Funderburk. I earned my M.S. in Clinical Mental Health Counseling from Troy University and specialize in offering compassionate, evidence-based care to children, teens, and adults. I work with individuals facing anxiety, ADHD, OCD, depression, eating disorders, grief, and other life concerns. Whether you want to master practical self-regulation tools or simply need a safe space to be truly heard, I offer a warm, empathetic environment dedicated to helping you heal and move forward.

Therapy is a collaborative healing process—not a one-size-fits-all model. I draw from CBT, DBT, IFS, play therapy, sand tray therapy, and a variety of other therapies to meet you right where you are.  I help you uncover your strengths, develop realworld coping tools, and process past experiences so you can navigate life with better ease and clarity.

Reaching out for support takes immense courage, but you don't have to navigate this season by yourself. Whether you are seeking practical coping strategies or a compassionate place to process heavy moments, I am here to support you every step of the way. I invite you to take the first step toward regaining your footing and schedule your initial session.
