Conleth Gilligan's six points helped Ballinderry deservedly edge out Dromore in Sunday's AIB Ulster Club SFC clash.
Michael McIver - the brother of Dromore manager Paul McIver - notched Ballinderry's goal in the first minute.
Four Paddy Montague points helped Dromore move ahead 0-7 to 1-3 but Ballinderry responded to lead 1-6 to 0-7 at half-time.
Dromore could never get closer than two points down in the second half as Ballinderry held on at Healy Park.
McIver notched Ballinderry's goal after only 48 seconds after Ronan McNabb had dropped a long ball from Ryan Bell.
Eoin McCusker quickly replied with a Dromore point but Ballinderry remained three clear by the eighth minute after Gilligan had scored the first of his six points.
However, Dromore dominated the next 15 minutes as they hit five out of the next six scores to take a 0-7 to 1-3 lead.
Dromore's fourth to seventh points all came from Montague but Ballinderry regrouped to hit the last three scores of the half to lead by two at the break with Gilligan, Enda Muldoon and Raymond Wilkinson on target.
Ballinderry twice stretched their lead to four in the 10 minutes after half-time as they led 1-8 to 0-7 and 1-9 to 0-8.
During the remainder of the match, the boot of Eoin McCusker helped Dromore cut Ballinderry's lead to two points on a couple of occasions but closer the Tyrone champions could not get.
In truth, Ballinderry wasted chances to put the game beyond reach with Muldoon and Colin Devlin in particular guilty of missing routine point-scoring opportunities.
Both teams had a player dismissed in the closing minutes of the game with Ballinderry's Martin Harney getting his marching orders for two bookings and Dromore sub Adrian McCaffrey receiving a straight red card for a bad tackle on Ryan Scott.
Ballinderry's win sets up a provincial semi-final meeting with All-Ireland champions Crossmaglen.
