About Sari Lessard, Ph.D.

Dr. Sari Lessard earned her Bachelor of Arts Degree in Psychology from the University of California, San Diego. She received her doctoral degree in Clinical Psychology from the Pacific Graduate School of Psychology in Palo Alto, California in 2004. As part of her training, Dr. Lessard completed her predoctoral internship and postdoctoral residency at Riverbend Community Mental Health, Inc. in Concord, New Hampshire where she provided outpatient psychological services to children, adolescents, and adults, including psychological testing and psychotherapy.

Dr. Lessard brings with her experience in treating individuals and families who struggle with issues of depression, anxiety, trauma and abuse (victims), parenting stressors, relationship problems, difficulty adjusting to life changes, grief and loss, child and adolescent behavioral problems, and self-injurious behavior. Dr. Lessard has also received specialized training in Dialectical Behavior Therapy (DBT), which helps individuals increase coping skills, emotion regulation skills, and interpersonal effectiveness skills, and in child sexual abuse treatment. In addition, she is a member of the American Psychological Association, and the New Hampshire Psychological Association.

Dr. Lessard utilizes a cognitive behavioral approach to treatment, which focuses on the relationship between thoughts, feelings, and behaviors, in conjunction with a psychodynamic and interpersonal approach to help clients eliminate or control troubling and painful symptoms so that they can more fully understand themselves and their environment, improve the quality of their interpersonal world, and return to previous levels of functioning. Dr. Lessard also values and respects the importance of genuineness, empathy and acceptance in the therapeutic relationship. She believes that these factors are necessary components to foster an environment of healing, insight, and growth.
