As a licensed clinical therapist and international psychologist with 15 years of experience, I work with adults experiencing anxiety, depression, and trauma. I view the therapeutic relationship as collaborative while still recognizing the journey is yours.
I have a fundamental belief in the transformative power of therapy. I come to this belief not just as a practicing therapist but as someone who was profoundly shaped by therapy as a young man. Having started my own journey with doubt and hesitation, I deeply respect the courage it takes to begin this work. Talking about therapy can feel tricky as jargon and platitudes often dominate the conversation. What I can say is this: I believe in your capacity—within a therapeutic relationship that intuitively feels right to you—to become a better version of yourself defined on your own terms.
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.
Often, struggles can become gateways to transformation. Many of the clients I work with are navigating low self-esteem, anxiety, depression, chronic stress, trauma, grief, or major life transitions that leave them feeling overwhelmed, stuck, or disconnected. You may be experiencing racing thoughts, emotional exhaustion, relationship difficulties, loss, or uncertainty about your direction in life. When we begin to explore these experiences with compassion and curiosity, new perspectives and meaningful change can emerge.
I believe telling your story in a safe, supportive space can be deeply healing. I want to hear about your hopes, dreams, challenges, and losses. My goal is to help you better understand your experiences, develop emotional resilience, and move toward greater clarity and self-acceptance. You are not alone, and I am here to walk alongside you as you move forward on your journey toward healing and growth.
