Hi, I’m Dr. Tirrell De Gannes, a licensed clinical psychologist in New York City. I support adults and couples through challenges like anxiety, OCD, trauma, grief, substance use, and relationship struggles. I’m passionate about helping you find clarity, purpose, and deeper self-understanding as you move through emotional pain and uncertainty.
My approach is tailored to you, blending evidence-based therapies like Cognitive Behavioral Therapy (CBT), mindfulness, and humanistic-existential perspectives. I create a collaborative, culturally aware space where you feel empowered to grow. Whether new to therapy or continuing your journey, I’m here to support you fully.
With experience in schools, private practices, and community mental health, I’ve seen firsthand that change happens when we have the right tools, space, and support. I’m honored to walk alongside you as you explore your path and embrace new possibilities.
