History

Cumann Naomh Treasa CLG was founded in 1963.

The club enjoyed almost immediate success securing 3 Antrim Minor Football Championship titles in the years 1969-71. The success of these teams fed into the newly formed senior setup. The senior team enjoyed a meteoric rise through the Antrim football divisions rising from Division 6 to Division 2 in successive years.

Following a narrow defeat in the replayed senior county final of 1976, the club finally secured their first Antrim Senior Football Championship title in 1979, beating local rivals St Johns. Under Br Ennis, the team went onto to contest 4 more senior finals. However they were unable to repeat the success of 1979. An Intermediate Hurling Championship title was secured in 1977.

In the early 80s, focus turned to securing a permanent home on the Glen Road. In 1992, a 100 year lease was signed for a 10½ acre site. In 1998, two grass playing pitches were opened by Jimmy Barry Murphy and the Cork hurling team, named McDonnell / Doherty Park. Jimmy Barry later sent the club a note the following year after his team clinched Liam MacCarthy citing their visit to the Glen Road. Despite securing an Intermediate Football Championship in 1993, the senior football team slipped into Division 3 at the turn of the millennium.

It was left to the hurlers to keep the club name prominent. In 2005, a Junior Hurling Championship was secured. The feat was repeated in 2008. Not to be outdone, the footballers secured the 2009 Junior Football Championship, the club's first since 1970, to ensure a return to the Intermediate ranks. This success was carried into the Ulster Club Junior Football Championship where the team battled through the autumnal months to an Ulster final against Emyvale, only narrowly losing out in a replay. They remain the only Antrim junior side to reach an Ulster club final.

The club returned to Division 2 in 2012 after a 14 year absence. A celebration of 50 years in 2013, was capped with acclaimed success on the pitch. In the last club game to be played at the old Casement Park, St Teresa's defeated Shaws Road rivals Rossa in the Beringer Cup final. The senior ladies team won their first silverware with an emphatic win over St Comhgalls in the Antrim Junior B Championship. The season was rounded off when the senior footballers defeated Portglenone by the narrowest of margins in the Intermediate Football Championship final at Glenavy.
