Lindsey is a vibrant girl who enjoys dancing and singing her favorite tunes. You'd probably never guess that she was born with two congenital heart defects and that she survived two open-heart surgeries by the time she was 6 months old. On Aug. 22, Lindsey will join a crowd of generous Milwaukeeans who will help her celebrate her 6th birthday at one of the city's most vibrant social events of the summer, Red Hot Summer Night.
