Education
University of Pennsylvania School of Social Policy as Practice, Master of Social Work, Clinical focus, 2015 — I hold a Master's in Social Work from the University of Pennsylvania, where I specialized in clinical social work and maintained a 4.0 GPA.
Work HistoryThroughout my career, I have worked in outpatient mental health and addiction treatment settings, providing therapy to adolescents, adults, and older adults facing a wide range of challenges. My experience includes individual therapy, group therapy, and supporting families through difficult life transitions. This work has allowed me to help individuals struggling with anxiety, depression, trauma, PTSD, grief, relationship difficulties, substance use, life stress, and emotion regulation. I practice from a trauma-informed perspective, recognizing how past experiences can shape the way we think, feel, and respond to life's challenges. My goal is to create a safe, supportive environment where clients feel understood while learning practical skills to move toward lasting change. One of the most meaningful experiences in my career was helping develop and implement an evidence-based Dialectical Behavior Therapy (DBT) program alongside a team of clinicians. Through this work, I led DBT skills groups and helped clients build healthier ways of managing overwhelming emotions, tolerating distress, improving relationships, and becoming more mindful in their daily lives. These skills continue to be an important part of my work because they empower clients with practical tools they can use long after therapy ends.
