I am a Licensed Clinical Social Worker (LCSW) and one of the founders of Waves Psychotherapy Group LCSW, P.C. with extensive experience supporting individuals, families and children navigating life’s challenges. My approach is rooted in compassion and understanding, tailoring treatment to meet the unique needs of each client. While I utilize a variety of therapeutic modalities, my practice is deeply grounded in trauma-informed care, recognizing the profound impact that adverse experiences can have on emotional and psychological well-being. I am committed to creating a safe and supportive space for healing and growth.
Whether you are seeking support for trauma, coping with illness, or striving for personal growth, I am here to help. Together, we can explore your strengths, build resilience, and work toward a more fulfilling and balanced life.
In addition to my work in trauma, I am oncology certified and have specialized experience in treating patients and their loved ones throughout the cancer and chronic illness continuum. From diagnosis through survivorship or end-of-life care, I offer support to help navigate the emotional, psychological, and practical aspects of the cancer journey.
