The plant staff was on hand Thursday to give tours to community members and the families of employees.
On Friday, tours were available for high school students in the morning and for community members again in the afternoon.
Among those attending Thursday evening were Wayne and Bev Buller. Wayne founded the company in 1987 when he started selling buildings from his home in Albion. The plant started in Albion and was later moved to its present location east of Albion. The staff has grown over the years.
In 2000, Sentinel was purchased by Global Industries, Inc. and is now one of five subsidiaries of that company.
Several plant expansions have taken place through the years. The plant currently operates with 60 to 70 employees.
