You don’t need to have it all figured out to start therapy—just a willingness to explore change, even if it feels uncertain. I support clients experiencing depression, anxiety, trauma, burnout, or challenges with sleep, focus, or relationships. Together, we work to stabilize symptoms, build resilience, and create healthy coping skills. My goal is to help you reconnect with purpose, find balance, and move toward healing—whether that’s feeling more joy, improving daily functioning, or safely managing medications.
I offer comprehensive psychiatric assessment, diagnosis, and individualized treatment planning with a focus on shared decision-making. My approach includes medication management when helpful, as well as holistic strategies like sleep, nutrition, and mindfulness to support lasting balance and well-being.
I know reaching out for help isn’t easy. If you’re feeling anxious, overwhelmed, or just not yourself, you don’t have to go through it alone. I’ll listen without judgment and at your pace. Together, we’ll create a plan that honors your goals and strengths. There is hope, and I’d be honored to support your journey.
