As a Licensed Clinical Social Worker in Florida and Illinois with over a decade of experience, I specialize in supporting individuals navigating anxiety, depression, trauma, identity exploration, and relationship challenges. My therapeutic approach is integrative and trauma‐informed, drawing from Cognitive Behavioral Therapy (CBT), EMDR, Internal Family Systems (IFS), mindfulness‐based practices, and psychodynamic therapy. Across all modalities, my priority is to create a compassionate, grounded, and non‐judgmental space where you can explore your emotions, your history, and the parts of yourself that are seeking relief or connection.
My mission is to help you achieve your personal goals by providing you with healthy, productive, meaningful strategies. My experiences in substance use counseling inspired me to educate myself further and become a Certified Clinical Trauma Professional. My experience in different treatment modalities allows me to apply DBT, ACT, CPT, and CBT to assist you in promoting prolonged, positive change. As a CADC, I employ Motivational Interviewing to promote awareness, change, and education.
I have over 3 decades of experience working in the fields of mental health and social work. I work with youth, adults, and couples who are struggling with trauma, depression, anxiety, ADHD, autism, relationship issues, and school refusal.
I have spent my career learning and translating theories into practice with individuals, families, couples, and groups. For the last few years, I've gained deeper knowledge working with trauma, anxiety, couples, and the LGBTQIA+ population.
