Meet Dr. Peggilee Wupperman, one of our senior clinicians at AICT. Dr. Wupperman is currently a professor at John Jay College/City University of New York and an assistant clinical professor at Yale School of Medicine. Dr. Wupperman completed her pre-doctoral fellowship at Yale School of Medicine, attended a postdoctoral fellowship at the University of Washington under the direction of Marsha Linehan (founder of Dialectical Behavior Therapy; DBT), and returned to Yale School of Medicine for an advanced postdoctoral fellowship in the Psychotherapy Development Center.
Dr. Wupperman is the developer of Mindfulness and Modification Therapy (MMT), a psychotherapy that helps clients break free from impulsive or addictive behaviors and build more fulfilling, meaningful lives.
Dr. Wupperman has extensive experience providing mindfulness-based treatments, DBT, cognitive behavioral therapy, interpersonal psychotherapy, acceptance and commitment therapy, and motivation-enhancement therapies. She specializes in treating clients who struggle with anxiety and/or problem behaviors (issues with alcohol/drugs use, binge eating, anger outbursts, chronic avoidance, etc.) that interfere with living lives that fit their values. She understands that these behaviors are often used to cope with difficult emotions and may seem impossible to resist. Thus, she uses a compassionate and empirically supported approach to help clients decrease problem behaviors, address the urges and/or anxiety that often occur when the behaviors are decreased, and begin to live lives that feel more fulfilling and meaningful.
She is currently accepting new clients. Reach out today to set up a consultation.
