About

Sam Lashley, Ph.D. Licensed Clinical Psychologist

Dr. Lashley is a licensed clinical psychologist with over twenty years of experience working with children, teenagers, adults, couples, and families. He completed his undergraduate degree at Washington University is St. Louis in 1989 and his doctoral degree in clinical psychology at the Catholic University of America (CUA) in Washington DC in 1998. While a graduate student, Dr. Lashley’s research focused on couple communication and conflict. In addition to the years of mentoring he received from Clifford Notarius, Ph.D. at CUA, he was fortunate to have the opportunity to train in John Gottman, Ph.D.’s lab at the University of Washington on a couple interaction assessment system. Training with and using this “microanalytic” coding system for his dissertation research became an invaluable part of his foundation as a couple therapist. After completing his clinical internship as a Harvard University Fellow at the Brockton VA Medical Center outside of Boston Massachusetts, he spent several years teaching and doing research on family conflict at Bowling Green State University in Ohio. Upon returning to the DC area, Dr. Lashley worked as a staff psychologist at the Lab School of Washington, providing psychotherapy to students of all ages, participating in IEP development, and conducting psychoeducational testing with children and adults from the community. He opened his private practice part-time in 2001 and full-time in 2004 where he provides a full range of assessment and psychotherapy services to children, adults, couples, and families.
