Healy lead by example throughout but was well supported by the talents of Aongus Callanan, Niall Callanan and Derick Reilly who ensured the Connacht side reached their third All-Ireland final in a row.
Defensively Ger Mahon, Tadhig Linnane Joe Lee and David Kennedy all impressed, even if their opponents did manage to chalk up 2-16.
Tipp's ultimate failure stemmed from their attack which couldn't maintain their earlier scoring spree. Shane O'Brien with 1-1, and Dara Hickey (0-4) who dominated the opening exchanges were eventually taken off leaving Richie Ruth to pose the sole threat to the Galway defence.
The Munster champions enjoyed a dream start when, after 25 seconds, David Sheppard threaded through a great ball to Hickey whose effort was blocked by 'keeper Aidan Ryan. But O'Brien was lurking and made no mistake from five yards.
Hickey added a point 30 seconds later and Galway looked in serious trouble. However the westerners switched their corner backs with David Kennedy quickly canceling out the threat posed by Hickey.
At the other end, Niall Healy landed three points on the trot followed by a fine Niall Callanan effort. By the quarter hour Galway were just a point in arrears.
Tippeary attempted to quell the powerful Healy but to no avail as the Cruaghwell youngster continued to lead the Galway charge. Tipp managed to keep their noses in front and points by Ruth and an excellent effort by goalkeeper Dara Egan from his own 65, had the Munster champions 1-8 to 0-8 in front with half time looming.
Then came the game breaking phase. Aongus Callanan reduced the deficit to two before Derick Reilly began a mazy run from midfielder, finishing with a thunderbolt goal to give the Connacht champions a one point interval lead and more importantly shatter Tipp mentally.
Galway maintained their momentum into the second half with points by the hugely impressive duo of Healy and Callanan. Indeed only the thickness of the upright denied Healy a goal after another great run.
The pressure on the overworked Tipperary defence told in the 38th minute when Damien Kelly's long delivery broke nicely to Derick Reilly who goaled with ease.
Tipp, to their credit responded superbly as Ritchie Ruth fired two points in quick succession followed by a flicked goal in the 48th minutes to retain the lead.
But Galway, as was their style simply upped gears again. Healy knocked over two close in frees as the Premier resistance began to evaporate
