University of Miami in Coral Gables, Florida, in 1991. He received his Master's (1994) and Doctoral degrees (1997) in clinical psychology from the Catholic University of America in Washington, DC.
During his professional training, he had placements at the Alexandria (Virginia) Mental Health Center and Affiliated Community Counselors in Rockville, Maryland. His predoctoral internship was at the Woodburn Center for Community Mental Health, Fairfax County's (Virginia) main mental health center. At the Woodburn Center, he worked with both the English and Spanish-speaking population at all age levels, co-led therapy groups, conducted psychological testing. He also completed rotations in the county's Emergency Service, and the Juvenile Forensic Psychology Unit of the Juvenile and Domestic Relations Court.
After completing his doctoral degree, he worked as a Staff Psychologist at the Lab School of Washington. The Lab School is a school for children with learning disabilities, from kindergarten through high school. Dr. Díaz worked with Lab School students in individual and group therapy, consulting to the teachers on classroom management issues, helping develop Individual Education Plans (IEPs), and helping students benefit from classroom instruction. He also participated in the Lab School's outpatient assessment services, providing psychological testing to members of the community, both adults and children.
Dr. Díaz has been in full-time private practice in Northern Virginia since 2000. His practice is bilingual (English/Spanish). The bulk of his practice is devoted to psychotherapy with individual patients. He works with children, adolescents, and adults, as well as working frequently with families and couples. He specializes in the assessment of learning disabilities in both English and Spanish, as well as ADHD. In general, he believes psychological testing to be a very useful process for understanding how individuals learn, as well as for understanding psychological functioning. Testing can guide treatment, educational placement, and provide information that cannot be acquired through clinical interview alone.
Areas of particular interest/specialization include working with children and adolescents, learning disabilities assessment, bilingualism and acculturation, men’s issues, post-deployment adjustment for members of the Armed Services, and the clinical needs of Roman Catholic clergy. He also works with language minority clients (mostly recent immigrants), often through local social service agencies. Also works with couples, including those dealing with bicultural marriages. More details on his testing practice can be found here.
In addition to his private practice, Dr. Díaz has taught doctoral-level courses in local graduate programs. He lectured on issues of assessment and cultural diversity at the American School of Professional Psychology (now Argosy University). He also taught the Practicum in Assessment in the Catholic University of America's Clinical Psychology Doctoral Program for several years. This course is for advanced clinical psychology students developing more sophisticated skills in psychological assessment. Finally, he continues to teach several courses on bereavement and counseling for the Diaconate Formation program of the Archdiocese of Washington.
Dr. Díaz is available for presentations to the community. Recent presentations include a mental health primer for the judges, staff, attorneys, clinicians, and probation officers of the Alexandria Best Practices Juvenile Court; a presentation on cultural awareness in working with immigrants and refugees for the National Association of Social Workers (DC Metro); a presentation on culture and ethics for the mental health staff of the St. Luke's Institute in Hyattsville, Maryland; and presentations on attachment and on understanding mental health assessment reports for the Virginia State CASA (Court-Appointed Special Advocate) Conference in Roanoke, Virginia. Most recently, Dr. Díaz presented on working with immigrant populations at the Virginia State-Wide Best Practices Courts Conference, also in Roanoke, Virginia.
In addition to his private practice, Dr. Díaz is an avid runner and has completed three marathons (Marine Corps twice and Chicago once), nine Ragnar Relays, and a number of half-marathons. He volunteers with service members through Give an Hour, has coached youth soccer, and volunteers with his sons' Cub Scout pack and Boy Scout troop.
