North Shore Psychology & BehavIORal Medicine Associates

NORTH SHORE PSYCHOLOGY AND BEHAVIORAL MEDICINE ASSOCIATES (NSPBM) is a private group practice made up of highly experienced clinicians who provide personal, individualized therapy to children, adolescents, adults, couples, and families.

Founded in 1984 by Dr. Paul Greenfield, who was at the time a psychologist on staff at Winthrop hospital, the practice was expanded in 1989 to help fill a gap in mental health services in the North Shore area. Since then, the practice has grown to include nine mental health professionals.

Even with growth, our practice remains rooted in its original values: personal, compassionate care tailored to our clients’ unique needs. NSPBM is not a clinic; we are a group of multidisciplinary specialists who treat clients with a wide range of mental health needs including, but not limited to: anxiety, depression, ADHD, adolescent behavioral issues, grief, life transitions, parenting, and divorce/remarriage. We screen every new client in order to provide a good “fit” between client and therapist. Our therapists also collaborate closely with primary care or specialty physicians, other mental health clinicians, and area hospitals in order to ensure continuity of care.

NSPBM accepts most major health insurance plans; please contact us to find out if we accept your insurance.



Paul Greenfield, Ed.D, M.S.


Dr. Greenfield is the director of North Shore Psychology and Behavioral Medicine Associates (NSPBM). He received his doctorate in counseling psychology at Boston University and a post-doctoral degree in clinical psychopharmacology at the Massachusetts School of Professional Psychology (MSPP). He is a member of the Allied Health Medical Staff at North Shore Medical Center and Melrose/Wakefield Hospital.

Dr. Greenfield specializes in mood disorders, including anxiety and depression, as well as stress-related disorders and medical illness management. His practice philosophy is to meet clients where they are “at”; therefore, he uses a blend of evidence-based behavioral approaches including cognitive behavioral therapy (CBT), insight-oriented psychodynamic therapies, grief therapy, and short- or long-term psychotherapy.

Dr. Greenfield also specializes in behavioral medicine, an interdisciplinary field of medicine that integrates psychophysiological therapies such as biofeedback, hypnosis, relaxation training, and CBT. Behavioral medicine integrates knowledge from the biological, behavioral, and psychological aspects of health in order to create a holistic approach to treating physical and mental illness. Research suggests that physical conditions are influenced by stress and poor health behaviors. Changing behavior can cause improved health, coping ability, and wellness.

When appropriate, Dr. Greenfield employs a behavioral medicine approach to help clients manage chronic illness, medication, stress, and anxiety.
