Teebi spent years on the editorial boards of medical and scientific journals, including the Editorial Board of the American Journal of Medical Genetics (2004–10) and Clinical Genetics (2005–10). He was a Founding and Editorial Board member of Clinical
Dysmorphology (1991–95). Teebi founded the first Arab neonatal screening program in
Kuwait. He also advanced the activities of Kuwait Medical Genetic center. The center was started in February 1979, and was inaugurated in November 1980.
