Cognitive Therapy Center Staff - New York State Licensed Clinical Psychologists

Dr. William Sanderson and Dr. Janet Klosko have Co-Directed the Cognitive Therapy Center of Long Island since its inception in 1988. They are both New York State licensed clinical psychologists and Founding Fellows of the Academy of Cognitive Therapy.

The staff of CTCLI practices cognitive-behavioral therapy, a short-term form of therapy that has been scientifically demonstrated to significantly help many psychological disorders, such as depression, anxiety, excessive anger, sexual problems, eating problems, physical stress symptoms, insomnia, impulse-control problems, social skills problems, and relationship problems.

The staff also practices schema therapy, a longer-term psychotherapy that focuses on healing lifelong self-defeating patterns, such as one finds in personality disorders. Schema therapy addresses eighteen schemas, including Mistrust/Abuse, Abandonment, Emotional Deprivation, Defectiveness, Social Isolation, Failure, Dependence, Undeveloped Self, Vulnerability to Harm, Subjugation, Self-Sacrifice, Approval-Seeking, Pessimism, Emotional Inhibition, Unrelenting Standards, Punitiveness, Entitlement, and Insufficient Self-Discipline.

In addition to Co-Directing the Cognitive Therapy Center of Long Island, Dr. Klosko is the Senior Psychologist at the Cognitive Therapy Center of New York. She also has a private practice at the Woodstock Therapy Center, in Woodstock, New York.

Dr. Klosko received her Ph.D. in clinical psychology from the State University of New York at Albany, and interned at the Brown University School of Medicine. While at Albany, she worked with David H. Barlow, Ph.D., researching and treating anxiety disorders with cognitive-behavioral therapy. She won the Albany Award for Excellence in Research, and the Dissertation Award from the American Psychological Association Section on Clinical Psychology as a Science. She is a Founding Fellow of the Academy of Cognitive Therapy.

Dr. Klosko has published a number of professional and self-help books: Reinventing Your Life (Young & Klosko, 1994); Cognitive-Behavioral Treatment of Depression (Klosko & Sanderson, 1999); and Schema Therapy: A Practioner’s Guide (Young, Klosko, & Weishaar, 2003). She has also published many scientific articles on the assessment and treatment of anxiety.

Dr. Klosko has a M.A. in English Literature from McGill University, and a B.A. in Comparative Literature from Union College.
