Meet Brad Dezotell, pyrotechnician behind Calgary's fireworks

When the skies over Stampede Park in Calgary erupt Tuesday evening with a choreographed dance of BOOM, BANG, CRACKLE, it’s because of months and hundreds of hours of careful preparation. The man behind the boom is Brad Dezotell, a veteran pyrotechnician, the founder of Fireworks Spectaculars, an Alberta company now recognized as a world leader in staging fireworks.
