Immediately after completing his solicitor's education in Newcastle Upon the Tyne in 1961, he proceeded home to assist the newly created nation of Ghana.

George L. Lamptey's service in the judiciary allowed him to witness dramatic transitions in Ghana's political ideology. He has attended several conferences both at home and abroad. He has presented at colloquiums and workshops at the Commonwealth Association of Magistrates and Judges. His presentations vary from Law on juveniles, Jurisprudence and the Administration of Justice, Human Rights and Peoples Rights law, and Intellectual Property Laws. Lamptey was named to the highest court of the Republic of Ghana in July, 2000. On December 7, 2000, Lamptey -- and fellow nominee, Mr. Justice Theodore Adzoe -- took their oaths of office. In many ways, Lamptey's desires to maintain high credibility for the Court and the law, the result of a general perception of judicial unity, has contributed greatly to his success in serving on Ghana's highest court. He is a devoted Methodist and preaches in selected churches.
George and Mary are blessed with three children, Esther, Gifty and Francis.
