Rebecca Grunberger, M.A.
Advanced Doctoral Extern
Rebecca Grunberger is a fourth-year doctoral student in Clinical Psychology at The Chicago School and provides therapy under the direct supervision of Dr. Alice Zafiris at Peak Wellness Group. She understands that starting therapy can feel intimidating and works hard to make the process feel less like a leap and more like a relief.
Rebecca works with adolescents and adults navigating eating disorders, OCD, anxiety, depression, trauma, and life transitions that can leave people feeling overwhelmed, disconnected, or unsure of themselves. She is especially passionate about helping clients repair their relationships with food, their bodies, and themselves. She believes recovery is about more than changing behaviors—it is also about reconnecting with your identity, values, and the life you want to live.
Curious by nature, Rebecca approaches each client’s story on its own terms and tailors treatment to the individual rather than relying on a one-size-fits-all formula. Her integrative, evidence-based approach draws primarily from Cognitive Behavioral Therapy, Dialectical Behavior Therapy, CBT-E for eating disorders, Acceptance and Commitment Therapy, and Family-Based Treatment when involving a client’s support system may help move recovery forward. She balances acceptance-based approaches with practical, solution-focused strategies so clients leave sessions with tools they can actually use—not just ideas that make sense intellectually.
Rebecca has experience providing individual therapy to adolescents and adults with body-image concerns, trauma, anxiety, depression, ADHD, and OCD. She has also conducted comprehensive psychological evaluations, including ADHD assessments and broader evaluations incorporating cognitive, personality, and self-report measures. Earlier in her training, she worked in an adolescent residential treatment setting, supporting teens experiencing significant mood, behavioral, and safety concerns.
As a advanced doctoral extern at Peak Wellness Group, Rebecca receives weekly individual supervision and ongoing consultation from Dr. Zafiris. This allows clients to benefit from Rebecca’s warmth, dedication, and developing expertise, alongside the support of an experienced licensed psychologist. Above all, Rebecca strives to create a space where clients feel safe enough to be honest, say the things that are difficult to say out loud, and know they will be met with empathy rather than judgment.
