Born December 28, 1949, Tim was a 3-time All-State goaltender at LaSalle Academy. There, he registered a miniscule 0.92 GAA and 27 shutouts in 54 career games with the Rams before accepting a scholarship to play at Boston University.

Playing for BU, Regan won two National Championships and set single season records for both goals against average and save percentage. As a member of Team USA he was awarded a Silver Medal in the 1972 Olympic Games and named an NCAA All-American.

When Tim began his collegiate career at Boston University, freshmen were not allowed to play on varsity teams. In his freshman year he posted an 8–0 record and a 1.12 goals-against average (GAA) as the team went undefeated at 17–0.

As a sophomore Tim posted a 2.82 GAA, ranking him second in the ECAC East Division, as the Terriers finished third in the ECAC Championships. The following year, he helped the Terriers claim the National title while setting BU records for both GAA (1.77) and save percentage (.929), which still stand today.

In August 1971, Regan was invited to try out for the U.S. Olympic hockey team. He declined in order to maintain his BU scholarship. His education was foremost. In 1972, Team USA played Tim’s BU squad in an exhibition game in which Tim stood on his head in a 4–4 final score. The following day, Team USA head coach Murray Williamson asked Regan to join the team. This time he agreed on the condition that he be guaranteed a trip to Sapporo, Japan, site of the Games, and that if he was not playing he could return to BU should they need him.

He played in 10 exhibition games with the National Team and traveled with them to Japan. When Team USA declared the playing roster for the Olympic tournament Tim was left off. He returned to BU when their goalie sustained a year-ending injury. Tim would then lead them to their second consecutive National Championship and Tim was named MVP. After the Olympics, teammate Robbie Ftorek presented Tim with his Silver Medal.

Tim was drafted by the Buffalo Sabres in the 1970 NHL Entry Draft. He played three seasons in the Sabres organization, primarily with the Cincinnati Swords and Hershey Bears in the AHL.

After retirement, Tim was a regular instructor at local hockey clinics and coached at both Cranston East and Bishop Hendricken High Schools.In 1993, he was inducted into the Boston University Hall of Fame. In 2000, he was enshrined in the MA Hockey Hall of Fame with the 1972 Olympic Team.
