Former leaders and members were among those who attended the event in Cranagill Methodist Church.
The company was formed in September 1983 by the late John Greenaway and Rev Brian Fletcher with three sections - Anchor Boys, Juniors and Company – and over the years it has gone from strength to strength.
The company is now under the leadership of current captain Bobby Dawson, with a full itinerary of activities on offer and the opportunity for members to take part in various competitions within the Portadown Battalion.
Photographer Tony Hendron went along to the anniversary service to capture some of the moments of this special occasion.
