As I am interested in pursuing primary care, I was very much intrigued by the osteopathic philosophy. I have heard from many folks on this board the emphasis on additional training in manual manipulation. Given osteopathic medical programs are also four years, where do they find the time to incorporate the additional training? Is there a tradeoff that osteopathic medical students are making when they undergo this additional training? Are DO medical schools staffed only by DOs? Thanks in advance for the info.
