Many Seventh-day Adventist business lay persons in the Nairobi and Central Kenya  Conference are members of Adventist-laymen's Services and Industries (ASI).

ASI members believe that their vocations can and should be a ministry to aid in the advancement of the great gospel commission (Luke 19:13; Testimonies vol.4, p. 469).

They are also committed to supporting the Seventh-day Adventist Church and its various outreach programs including, health,education, evangelism, community services, family concerns, and special projects.

The ASI philosophy promotes a Christ-centered lifestyle, manifested by a commitment to be in daily partnership with God. Members seek to live out God’s love in their own lives and share that love with the millions of people they encounter in their business and professional activities each year.
