Ministry in England involved work with troubled youth, and out of a desire to set up a centre for reconciliation and rehabilitation, he received the divine mandate to go home to Jamaica and establish a Christian Centre with the name Teamwork Associates. In 1971, 20 years after leaving Jamaica he returned and immediately got involved in the prison ministry with others from the Kingston Open Bible Church.
A centre was established in August Town and at his home base in Barbican, and the company Teamwork Associates was formalized in 1973. Again through divine intervention, the property now known as Teamwork Christian Centre was given to Teamwork Associates for the establishment of a Christian Centre. From January 1975 the work at the Centre progressed until now on a hillside in Torada Heights, stand a staff house, extended guest facility, conference room with dining room and kitchen, offices, a three storey school building and a church. All these testify to the faithfulness of God to those who are obedient to carry out his mandate. At 84 years old, Menzie Oban still serves in spiritual and practical ministry giving thanks to God for the strength to carry on.
Winsome hails from the parish of Manchester where she completed high school before moving on to the Mona campus of the University of the West Indies in 1964. She had become a Christian in 1962 and found opportunity for fellowship, spiritual growth and Christian service in the ministry of the Inter-Schools and Inter-Varsity Christian Fellowship. Having chosen teaching as a career, Winsome acquired a Diploma in Education at UWI and then taught at Wolmer’s Boys School in Kingston.
In 1973 she studied for an Advanced Certificate in Education at the University of Bristol in England and returned to Jamaica as a lecturer at the Mico Teachers’ College in Kingston. The call to full time Christian ministry was received in 1974 while attending the Lausanne Congress on World Evangelization in Switzerland, and was answered in 1976, when she was sent from Deeper Life Ministries in Kingston to serve in the ministry of Teamwork Associates in Montego Bay.
Alongside administration and education, Winsome continued academic work and earned a Masters in Christian School Administration from the Oral Roberts University in the USA in 1994 and a PhD from the University of Birmingham in England in 1998.
