After receiving my bachelor's in psychology from SUNY New Paltz in 2013, I worked as a medical assistant with individuals with developmental disabilities. From there, I recognized the need to promote mental health and a balanced way of living. I completed my master's in clinical Mental Health Counseling through Walden University in 2021. My goal is to guide individuals towards cultivating their own sense of independence, ability to utilize healthy coping strategies, and regain control over their lives. I work with children, adolescents, teenagers, adults, couples, and families as they begin their journey through processing adjustment changes, anxiety, depression, anger, grief, trauma, among other symptoms. Through the therapeutically proven interventions from CBT, DBT, person-centered therapy, and mindfulness, we can begin to explore triggers, symptoms, and challenges in a safe, respectful environment.

Donna begins each therapeutic relationship by establishing trust and safety, encouraging honest dialogue around personal and family challenges. She integrates education, reflection, and resource sharing on topics like communication and conflict resolution. Together with patients, she develops personalized short- and long-term goals rooted in their individual and cultural values, ensuring therapy supports meaningful and lasting growth.
