After receiving a Veterinary Technology degree, what would one have to do to become a veterinarian?

You'd have to go back to college and earn a bachelors degree in something while taking the pre-vet classes. It's likely few to none of your vet tech classes would count towards this. Then you'd have to go to vet school for 4 years. Being a vet tech doesn't save you any time. And many vet offices will train you so you don't need a degree for that at all.
