About
Hello! I’m Dr. Jonathan Thomas-Stagg, a licensed clinical psychologist based in Illinois. I also have the Authority to Practice Interjurisdictional Telepsychology through PSYPACT, so I’m happy to work with individuals across 43 states.
One of the things I enjoy most about psychology is getting to know people and helping them better understand themselves. Every person has a unique story, and I believe that understanding that story is often the key to making sense of the challenges, strengths, and patterns that show up throughout life. Often, people seek psychological services because they feel there is something “wrong” with them; please always know there is far more right with you than wrong with you.
Many of the people I work with have spent years wondering why certain things seem harder for them than they do for others. They may be exploring questions about autism, ADHD, anxiety, relationships, or simply trying to understand themselves more clearly. My goal is to create a space where you can talk openly about your experiences and feel genuinely heard, respected, and understood.
I see assessment as much more than a process of checking boxes or assigning diagnoses. It’s an opportunity to step back, look at the bigger picture, and better understand how your experiences, personality, strengths, and challenges fit together. Whether an evaluation results in a diagnosis or simply provides new insight, I hope you leave with a clearer understanding of yourself and a greater sense of confidence moving forward.
About myself, I’m a father of two teen boys, who present the most amazing challenges and joys in my life. I’m deeply interested in philosophy, cosmology, and art. I love to cook. And though I am fairly introverted, I enjoy 1-1 connections with the people closest to me in life, learning about others, and understanding the world through others’ lenses.
I’ve always been fascinated by the different ways people experience and make sense of the world. Throughout my career, I’ve worked with people from many different backgrounds and life experiences, and I’ve found that some of the most meaningful conversations happen when someone begins to understand themselves in a new way.
I enjoy working with autistic and neurodivergent adults because the assessment process can provide clarity around questions people may have carried with them for years. For some, that means finally having an explanation for experiences that never quite made sense. For others, it’s an opportunity to better understand their strengths, needs, and the ways they interact with the world around them. Regardless of the outcome, my goal is to help you leave with a deeper understanding of yourself.
I don’t believe people can be reduced to a diagnosis. We are all shaped by our experiences, relationships, successes, setbacks, and the ways we’ve learned to adapt throughout life. While assessment often focuses on understanding challenges, I think it’s just as important to recognize strengths, resilience, and the qualities that make each person unique.
My approach is collaborative and grounded in curiosity. I bring my training and experience, but you bring expertise about your own life. By working together, we can build a more complete understanding of who you are—not just what you’ve struggled with, but what has helped you succeed and what makes you who you are.
My hope is that you leave the process feeling understood, with greater self-awareness and practical information that helps you move forward with confidence.
