Louis Mary Shea was an American Dominican friar who spent 19 years in Kenya doing social ministry in Kisumu, after having spent 38 years in Nigeria (1953-1991, mostly in Gusau and Sokoto).   He was well trained in financial accountability and had a ministry of financial counseling to small business owners, families concerning their family financial planning, and developed a sort of cooperative union.    He gave a lot of retreats and was a very edifying preacher and spiritual director.  He died of cancer in Kisumu in February 2010.
