Pros
As someone who has worked for almost every corporate veterinary group possible, I can say with confidence that the NVA model suits my needs best. The entire staff is given real autonomy from management. As a medical director I have absolute discretion over my medical protocols, inventory items and management style. Yes, I work for a corporation and am expected to maintain a profitable hospital but I don't see how that would be different if I were a private owner. NVA allows me the ability to practice cutting edge medicine without having to navigate the soul-crushing complexities of HR/accounting/payroll. I am finally able to purchase the best drugs and equipment that allow me to practice the most rewarding type of medicine. Based on annual performance hospitals also qualify for additional capital expense purchases that do not come out of the clinic's finances.
Cons
My medical benefits are not extended to my immediate family (this is keeping me from getting married!) I do not have a 401-K matching plan. My medical benefits are meager and overpriced.
