Tammy attended Markham District High School. She was rated Canada's top female basketball prospect by the Toronto Star.

College
Tammy attended Rutgers University. She was a member of the first Scarlet Knights team (1999-00) to ever reach the NCAA Women's Final Four, she ranks third in Rutgers' history with a .574 field goal percentage, fourth with 148 blocked shots and is tied for first with 130 games played... She is eighth with 304 free throws made, 12th with 685 rebounds and 16th with 1,246 points.

WNBA
Tammy was selected by the Charlotte Sting, the 18th overall pick in the second round of the 2001 WNBA draft.

She finished the 2004 season ranked second in the WNBA in blocks (2.09 bpg), and indeed, was the Sting's all-time leader in blocks in 2004 with 196 career blocked shots, and as of 2006 only the 10th player to achieve 200 blocks.

In 2002, she was selected for the 2002 WNBA All-Star Game, becoming the first Canadian WNBA player to participate.

After the 2006 season ended, the Sting folded and most of the players were entered in a dispersal draft. Because Tammy was an unrestricted free agent at the end of the 2006 season, she was exempt from entering the dispersal draft.

On March 22, 2007, she signed a contract with the Indiana Fever.

Personal
As a senior, Tammy received the nickname "Simba" (from the Disney movie The Lion King) due to her coming of age at Rutgers.
