Flyers general manager Paul Holmgren announced the extension Wednesday. Terms of the deal were not disclosed.
Laviolette has compiled a 122-73-26 record since taking over for John Stevens in December 2009. He led the Flyers to an appearance in the Stanley Cup finals that season after Philadelphia bested Boston in the conference semifinals despite losing the first three games of the series.
The Flyers collected 47 wins in each of the last two seasons only to be knocked out in the Eastern Conference semifinals, most recently by the New Jersey Devils.
Holmgren says Laviolette has done "a terrific job" to earn the extension.
I had one really not-good game. I came back to the hotel and he [his father] was on Skype. My mother called first and said, 'Your father wants to talk to you.' So he moved my mother away, and he yelled at me for like 30 seconds. I understood him, and then he said, 'I'm done.' And he was gone. The next game I got my first shutout.
