I have been contemplating applying to DO school for quite some time. The problem I have is that in 1995 I enrolled in Podiatry school. I failed 3 classes (the reasons which I will not get in to) and was dismissed. Since then I have been involved in clinical research and own a research company that conducts clinical drug trials. I want to apply to DO school but if the past failure will automatically disqualify me, then I do not want to waste the time and the money. I graduated college in 1993 with a 3.2 GPA. MCATs were average. Any advice on whether or not to pursue the application process?
