Dr. Larry Shapiro, Ph.D. — Licensed Psychologist & Founder of Quantum Behavioral

Dr. Larry Shapiro earned his PhD in Clinical Psychology in 1990 and has spent more than three decades helping adults overcome anxiety, depression, trauma, substance use concerns, relationship difficulties, and other complex emotional challenges. Throughout his career, he has pursued advanced training in trauma treatment, military psychology, severe anxiety disorders, and psychedelic-assisted psychotherapy.

His therapeutic approach evolved from a simple belief: psychotherapy should help people get better, not merely learn to live with symptoms. Treatment is active, structured, and focused on identifying and changing the patterns that keep people stuck, with the goal of creating meaningful and lasting improvement.

In 2022, Dr. Shapiro founded Quantum Behavioral, LLC, a telehealth-only psychology practice serving adults in Missouri, New Jersey, and more than 40 states through PSYPACT. He has found that telehealth often allows people to engage more comfortably and authentically in therapy, creating greater opportunities for insight, progress, and lasting change.

In addition to his clinical work, Dr. Shapiro serves as an Adjunct Instructor of Psychiatry at Washington University School of Medicine and as a clinical advisor to the Center for Holistic Interdisciplinary Research in Psychedelics (CHIRP). He continues to remain actively involved in education, consultation, and emerging evidence-based approaches to mental health treatment.

Sometimes the mind becomes stuck in patterns that make situations feel more threatening, hopeless, or overwhelming than they actually are. We may expect the worst, overestimate danger, or treat temporary setbacks as permanent problems. These patterns can contribute to anxiety, depression, trauma-related distress, low confidence, relationship difficulties, and other emotional challenges. Over time, they can interfere with work, relationships, decision-making, and overall quality of life.

My approach focuses on identifying unhelpful patterns of thinking, understanding the emotions they create, and changing the behaviors that keep the cycle going. The goal is not simply to “think positively,” but to think more accurately, respond more effectively, and develop greater psychological flexibility and freedom in daily life.

Drawing on more than 30 years of clinical experience, I integrate evidence-based psychotherapy with both traditional and emerging approaches to treatment. My work is particularly focused on helping adults with anxiety, depression, trauma, and treatment-resistant conditions, especially when previous therapy, counseling, or medication has provided only limited relief.

Therapy is active, structured, and collaborative. Rather than remaining stuck in understanding problems, we work toward resolving them and creating meaningful, lasting change.

I chose the name Quantum Behavioral to reflect my belief that small, deliberate changes in thinking and behavior can lead to significant improvements in how people feel and function. In clinical practice, I have found that meaningful change does not always require years of therapy or repeated insight into the past.

Many adults seeking treatment for anxiety, depression, trauma-related distress, or long-standing behavioral patterns are looking for more than understanding—they are looking for change. In my work, progress often comes from applying a clear psychological framework with structure, precision, and accountability to directly interrupt and change unhelpful patterns.

When thinking patterns and behaviors are identified and addressed in a focused way, long-standing emotional cycles can begin to shift. The goal of this approach is to help people achieve measurable improvement in daily life, greater emotional stability, and more effective ways of responding to stress and challenges.
