Work History

As a Licensed Clinical Social Worker (LCSW) practicing in Pennsylvania, New Jersey, and Delaware, I bring extensive experience in outpatient mental health and addiction treatment settings, serving diverse individuals across the lifespan. With advanced training in Dialectical Behavior Therapy (DBT), I provide targeted support to individuals facing overwhelming emotions, unstable moods, suicide ideation, and panic attacks. Combining cognitive-behavioral therapy (CBT) with mindfulness practices, DBT offers a versatile approach to emotional regulation, interpersonal effectiveness, distress tolerance, and mindfulness skills. I have had the privilege of assisting clients dealing with intense anger, chronic feelings of emptiness, mood swings, and individuals struggling with suicidal thoughts or self-harming behaviors. My goal is to equip individuals with the tools and resources to cope and improve overall well-being. DBT's benefits extend beyond acute challenges, making it applicable to personal growth and improved well-being. Whether you are navigating relationship conflicts, stress management, self-esteem issues, or life transitions, DBT cultivates resilience, improves communication, and fosters a more fulfilling life. Guided by empathy and respect, I foster a nurturing and non-judgmental therapeutic environment where each person feels genuinely seen and heard. I am dedicated to building a strong therapeutic alliance based on trust and mutual understanding, empowering clients to explore their inner selves, discover strengths, and navigate their path toward growth and resilience. Are you looking for relief from anxiety, depression, grief, or loss? Perhaps you want more ways to cope and manage extreme emotions or moods. You may just recognize feeling "stuck" right now and are unsure what to do next. If you're seeking a compassionate and dedicated therapist, I invite you to contact me for a free 15-minute phone consultation. Together, we can determine if my approach to therapy is the right fit for you.
