About the Method

Nysa Therapy integrates specific techniques from many therapy models with the specific purpose of effectively treating personality disorders. This includes solution-focused, psychodrama, relational, strategic, psychoanalytic, DBT, family systems, interpersonal, Jungian, transactional analysis, client-centered, and feminist therapies. We have combined these approaches in order to enact specific wellness exceptions within the therapeutic relationship that simultaneously deconstruct defensive structures and manifest self-sustaining individuation experiences.

About Nysa

The Nysa Therapy Story

Nysa Therapy was formed out of necessity from the personal experiences of Dr. Stephen M. Diggs. It came at a time when he was struggling with his own personality disorder and found that even with a PhD in psychology he was unable to manage his thoughts and inclinations towards self-destructive behavior. After seeking help from a number of qualified professionals and making little to no progress he set out to find a way to treat these disorders and concurrently himself.

Dr. Stephen M. Diggs turned to the great theoreticians in psychology including Freud, Jung, Rogers Erickson, Satir, DeShazer, Millon, and Masterson to find new ways to imagine these disorders and discover unique interventions to bring about real, significant, and permanent change. The model of Nysa Therapy integrates specific techniques from many therapy models including solution-focused, psychodrama, psychoanalytic, client-centered, and feminist therapies in order to enact specific wellness exceptions within the therapeutic relationship that simultaneously deconstruct defensive structures and manifest self-sustaining individuation experiences. This unique and integrated approach to treatment is at the foundation of Nysa Therapy and informs our practice at the Nysa Therapy clinic every day.

Dr. Stephen M. Diggs started Nysa Therapy with the assistance of training coordinator and administrator, Mary Wittenberg, in 2015 to continue the mission of treating and curing personality disorders. The clinic expanded in 2016 with a new office in Chico, CA and the addition of two new clinicians Adam Aaronson, MFTI and Ta’Shanne Horn, ASW. With the addition of two clinicians and the continued training of mental health professionals in the area we are constantly expanding the development of Nysa Therapy, growing more skilled, and getting ever-closer to a cure of personality disorders. As we continue to grow, we hope to effectively demonstrate the positive outcomes of our method through expanded use of valid and reliable measures, bring on more clinicians to work directly with us, and expand our training to a fully functional online learning management system.
