With over 30 years of experience, I help adults manage sleep, stress, anxiety, depression, and ADHD. People often describe me as kind, perceptive, with a good sense of humor. My approach combines active listening, mindfulness, CBT, and applied neuroscience. We'll work together to create a plan tailored to your needs to help you focus and move forward with confidence. I'm an LCPC, Board Certified in Neurofeedback, with a certificate in CBT-I for insomnia and other sleep concerns.
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.
