Dr. Nathan McClelland is a clinical psychologist who specializes in providing individually tailored, evidence-based psychotherapy with a focus on increasing self-understanding – the way one makes sense of their own history, thoughts, feelings, and behaviors – and the examination of how and why individuals often engage in distressing or ineffective behaviors.  Dr. McClelland assists patients in improving their awareness of these patterns, and in the process make changes to allow for a richer and more meaningful life.

Dr. McClelland works with individuals, couples, and groups, from late adolescence throughout the adult lifespan, and treats a range of presenting concerns, including (but not limited to) depression, anxiety, life transition issues, challenges of young adulthood, personality disorders, anger, and interpersonal/relationship difficulties.  Prior to joining Morris Psychological Group, Dr. McClelland completed his postdoctoral training as a Fellow of Psychology in Psychiatry at New York-Presbyterian Hospital – Weill Cornell Medical Center, where he developed expertise in both psychodynamic and cognitive-behavioral interventions for a range of behavioral issues.  Dr. McClelland has also gained specialized experience in Transference-Focused Psychotherapy for borderline and narcissistic personality disorders, Affect Phobia Therapy for depressive and anxiety disorders, and Exposure and Response Prevention for obsessive-compulsive disorder.

Dr. McClelland graduated summa cum laude from Boston University in 2008, earning a Bachelor’s of Arts in Psychology with a minor in Business Administration, before beginning graduate training in psychology at St. John’s University in Queens, New York. Dr. McClelland earned his Ph.D. in Clinical Psychology from St. John’s in September 2013 after successfully defending his doctoral dissertation and completing the Predoctoral Psychology Internship Program at Nassau University Medical Center in East Hempstead, New York.

Dr. McClelland has conducted research with the primary aim of understanding the process of psychotherapy – how and why it is helpful – and exploring the potential for improvements.  Dr. McClelland is a member of the New Jersey Psychological Association and Morris County Psychological Association.   Dr. McClelland is currently licensed as a psychologist in the states of New York and New Jersey.
