OP- I did the same thing you are wanting to do. In my early 20s, I left a barn manager position for a (non-certified) vet tech position for the same reasons. Plus, my goal at the time was to become a vet.
My first go round as a vet tech, I was blessed to be hired at a university hospital. I received holidays, vacation, sick days, excellent benefits, and better than usual pay. And while I loved the work and my co-workers, it killed my dream of becoming a vet. The hospital was one of the most toxic and poorly managed work environments I have ever been in. A lot of disgruntled CVT/LVTs were “stuck” there because while there are plenty of job opportunities for vet techs, there are very few places where you can receive livable pay and benefits.
Veterinary medicine is my passion, but I have left the vet tech field full time because it’s not a viable career. I still do some part time vet tech work now and again (both small and large animal) and I see the same things across the board-- unbelievably low salaries, no benefits, no time off, poorly managed work environments, etc. It’s a high responsibility profession with a high risk of injury, yet vet techs are often compensated the same or worse than the high school kid bagging your groceries.
I say all this not to discourage you-- there ARE good places to work out there and the job can be extremely rewarding. If you end up at a good place, make sure you appreciate it!
One of my dream jobs would be to direct a vet tech certification program. But… I have a moral dilemma about doing so because it can be such a tough career with little room for advancement. I do wish AVMA would align the coursework and certification process so that earning a CVT could be used a “stepping stone” for someone who may want to continue their education down the line and earn a DVM. There are some damn fine CVTs out there who would make exceptional vets, yet it’s all but impossible for a working adult to drop everything and go back to school for up to eight years full time. Especially when you can’t even save up money for it because you only make $10/hr.
