About ME


My name is Maria Sullivan, and I am a Licensed Clinical Social Worker (LCSW) practicing in Pennsylvania, New Jersey, and Delaware. My therapy practice is dedicated to providing comprehensive mental health support, including individual and group therapy sessions, insightful blogs, and valuable resources. Whether you're seeking support for yourself or a loved one, I'm here to guide you on your journey toward improved well-being.


I hold a Master’s in Social Work from the University of Pennsylvania (2015). During my studies, I gained invaluable experience through internships that shaped my therapeutic approach. At the University of Pennsylvania Hospital's Medical Intensive Care Unit, I assessed and coordinated care for patients, honing my skills in crisis intervention and patient advocacy. Additionally, I worked with teens and adults with developmental disabilities at the Jewish Family and Children's Service, where I developed a deep understanding of diverse needs and inclusive care strategies. These experiences provided me with a strong foundation in both medical and community-based settings, enabling me to offer comprehensive and compassionate support to individuals.

Work History

I have extensive experience in outpatient mental health and addiction treatment settings, serving a diverse range of individuals across the lifespan. My work involved counseling individuals, couples, and families, as well as facilitating group therapy sessions focused on mental health and substance use disorders.

I have advanced training in Dialectical Behavior Therapy (DBT), and my team and I created and implemented an evidence-based DBT program. Through this program, I had the privilege of helping clients gain essential skills to manage their emotions, improve their relationships, and enhance their overall quality of life.

My Approach

I specialize in supporting individuals facing grief and loss, trauma, anxiety, depression, life transitions, and substance abuse. My approach integrates Dialectical Behavior Therapy (DBT) with Cognitive Behavioral Therapy (CBT), providing a comprehensive framework for emotional regulation and personal growth. While CBT focuses on changing negative thought patterns and behaviors, DBT emphasizes learning skills for mindfulness and emotional regulation. Additionally, my holistic approach addresses physical, emotional, mental, and spiritual aspects of well-being. Using evidence-based techniques combined with holistic practices, I am dedicated to helping you on your journey.

I provide individuals with the tools and resources they need to cope and thrive by fostering a supportive, comfortable space where you feel genuinely seen and heard. Guided by empathy and respect, I cultivate a nurturing, non-judgmental environment. I am committed to building a strong therapeutic alliance based on trust and mutual understanding, empowering clients to explore their inner selves, discover their strengths, and navigate their path toward growth and resilience.


Contact me to take the first step toward a life of meaning, growth, and well-being.
