Is this for Epi programs? If so, I received an invitation request late January for OHSU and received an acceptance early this month. For OSU, I applied a week or so before 12/1, my application was reviewed early January, and I was accepted the end of January. I haven't heard anything for Colorado, but I did applied on 2/1.
Regardless, I had average GREs, and I knew people who got into Epi PhD programs with lower than average scores. From my perspective, it appears that the majority of schools look at your application as a whole, and the importance of GRE scores, especially if you already have a Masters, seems debatable (although they appear to be important for some funding opportunities). I think your experiences are great, so don't lose hope yet!
