As Director of Dr. Oakley, Yukon Vet, Bushala spent years filming in one of the harshest environments on the planet, where sub-zero temperatures and unpredictable wildlife were all part of a normal day's work. The hit Nat Geo WILD series followed the extraordinary life of Dr. Michelle Oakley and grew into one of the network's longest-running and most popular original productions, spanning 12 seasons and more than 90 episodes.
