Dr. Pelham joined the University of Pittsburgh faculty in the Department of Psychiatry in the late 1980s, bringing with him expertise in the treatment of children with ADHD.  He recruited Dr. Brooke Molina to Pittsburgh where together they began the Pittsburgh ADHD Longitudinal Study (PALS) which continues today in its 30th year dating back to its first funding to Dr. Molina in 1994.  Dr. Pelham developed the Summer Treatment Program for ADHD (STP) that treated hundreds of children in the Pittsburgh area before he left in 1996 for SUNY at Buffalo followed by Florida International University where he founded the Center for Children and Families.  Children who participated in the STP in Pittsburgh have contributed in large numbers to the PALS which has made it a unique source of information in the US about long-term course of ADHD through adolescence into adulthood.  Dr. Pelham was a strong advocate for evidence-based treatment of childhood ADHD and he contributed massively to the scientific database in this regard and also populated the mental health field with many clinicians and scientists trained in his programs.  Additional details regarding his life and career may be found at FIU, the Pittsburgh Post Gazette, Legacy, and the New York Times.
