Dr. Elizabeth Nellamattathil, PhD, LPC, LCPC

Over the years, I’ve had the privilege of walking alongside people through some of life’s hardest and most meaningful moments. My experience has taken me into many different settings, from hospitals and residential treatment centers to college campuses and private practice. Each space has deepened my appreciation for how complex, courageous, and deeply human the healing process is.

One of the most rewarding parts of my journey has been working with undergraduate and graduate students at Northwestern University. There, I supported students facing a wide range of concerns, including adjusting to new environments, managing academic pressure, navigating relationships, and figuring out next steps in their careers. These experiences reminded me just how much strength people carry, even when they feel lost or overwhelmed.

In my practice, I work with both individuals and couples who are navigating life transitions, relationship challenges, identity questions, and emotional struggles. Whether you’re feeling stuck, disconnected, anxious, or simply trying to find your way, I offer a space where you can feel genuinely heard, respected, and supported.

My approach to therapy is grounded in Person-Centered Therapy, which means I focus on building a relationship where you feel truly seen and safe. I believe that meaningful growth begins when we feel understood and accepted just as we are. Alongside this foundation, I also incorporate a range of evidence-based approaches tailored to your specific goals so that therapy feels both compassionate and effective.

Outside of my work with clients, I’m also a clinical supervisor and educator. I’m passionate about mentoring the next generation of therapists, helping them grow into thoughtful, culturally humble, and well-trained professionals who can offer others the same care and support.

More than anything, I believe therapy is a place to reconnect with yourself, your values, and your hope. You don’t have to have it all figured out. We’ll work together to uncover your strengths, build resilience, and move toward a life that feels more connected, purposeful, and true to you.
