He obtained his West African School Certificate in 1965 and his Higher School Certificate in 1967.

He subsequently earned his Bachelor of Laws degree from Ahmadu Bello University in 1973 and a Master of Laws degree in 2001.

His engagement with public institutions also included service as Legal Adviser to the Benue State newspaper, Popular Voice. He was subsequently appointed by the state’s Military Governor as Chairman of the Benue Printing and Publishing Company Limited.
