Phantom Regiment staff members Paul and Sandi Rennick, who have helped build the corps’ drum line into a national power, recently gave birth to a son.

Colin Francis Rennick was born at 10 a.m. Dec. 21, coincidentally, the same birthday as the proud new mom.

He was 6 pounds, 5 ounces and stretched 18 1/4 inches long.

Paul is the Phantom Regiment’s percussion arranger and caption head, while Sandi teaches the front ensemble. The percussion section won its first Fred Sanford High Percussion Trophy at the DCI World Championships in 2006.
