Mentorship isn't sitting down and discussing every case or having rounds. Mentorship is really just another vet being present to guide you along, especially for those first few months when you are figuring things out. Some new grads are quicker to jump into being alone than others. Some are forced into being alone. I spent the first week shadowing the vets into exam rooms, seeing how they talk with clients, explain treatments/diagnostics, discuss prognosis, etc. It gave me some good insight to how different each vet is in that approach. Especially since GP is much different than that of vet school. I also used this time to learn the computer system as well as learn where everything is located in the clinic. After that first week, the vets allowed me to decide if I wanted them following me or if I wanted to go alone. So....off I went. I was practicing alone starting about 6 weeks after graduation. I was fairly comfortable with that by then. Sundays were single doctor days, so they started me off alone on Sundays, then when we lost the other doctor, I became basically 2 doctors trying to keep the clinic afloat. That is what burned me out.
It is also nice to have a vet available for surgeries. I mean, not in exam rooms, but actually available to assist for at least your first few surgeries. If a pedicle slips during a spay, it is nice knowing you have those extra hands around to jump in without feeling guilty of pulling the doctor away from appointments. Yes, this will financially impact that clinic a bit, but if a clinic is looking to hire new grads, they should be ready to build this in some. Once you get more confident in your surgical ability then this help isn't needed. I never go this. I also did not get to spay any animal throughout vet school. So, needless to say, I wanted more surgical mentorship.
Actually, I advise any graduating vet to figure out if they will get CE allotment, most clinics provide it. It is an investment in their doctors and therefore an investment into the clinic. It is becoming more uncommon for them to not provide CE money.
