Branigan and his family moved to the United States when he was seven and settled in Nutley, New Jersey. In 1993, he graduated from Nutley High School. He attended Rutgers University where he was a 1996 Third Team All American soccer player.
On February 1, 1997, the Dallas Burn selected Branigan in the second round (sixteenth overall) of the 1997 MLS College Draft. The Burn released him during the preseason and he signed with the Orlando Sundogs. When the Sundogs began to experience financial difficulties, the team released Branigan and several other players. He played three games for the Carolina Dynamo. He then joined the Worcester Wildfire for the remainder of the 1997 season. In 1998, he signed with the Hampton Roads Mariners and remained with the team for three seasons.
Branigan is now the coach of the James Caldwell High School boys soccer team, of which he has coached for the last 5 years.
