I don’t know anything specific about the program, but be sure you know exactly how much of a commitment they require after the program…most of those things require that you work for them for a certain time period after the program ends. Not sure how long but if it’s more than a year and you don’t think er is your ultimate goal, it may be better to consider an internship with a shorter commitment instead.
VEG seems to be either loved or hated and not much in between but I don’t have personal experience with them. I believe BluePearl also has a similar program and also maybe Thrive, so if you’re looking for a similar type program with a different company they exist.
I’d recommend you talk to other shelter vets and see what they think too; to me it seems like the caseloads and budgets and everything would be quite different in shelter med vs specialty er, but that could be naive of me and I’d definitely defer to people in those fields. After my internship I was comfortable treating a lot of emergencies, but that doesn’t translate over to common GP stuff super often and I worry shelter is similar.
