Thanks so much for your response, it really lifted my spirits! I do have to make one revision...scratch the 1200 GRE, I got a 1060 (took it back in 2009). With that being said I'm wondering if I should take the GRE again...I'm really trying to avoid that route!
No problem that's what we are here for!
As I kind of alluded to before, the GRE is a metric that can be used to assess many things. Some graduate programs use it as a weeder tool considering the high number of applicants they receive (upwards of 300-600+ depending on the program). The general notion for GRE scores is: Too low of a score (under 1000) will raise a red flag, a score above the cutoff (1000-1200) will not hurt you nor particularly help you, and a score in the high 1300s could possibly help to overcome deficiencies in GPA (assuming your GPA is low, under 3.2).
As a rule, I always tell people who may not have had the best scores on the GRE that it is easier to "explain away" to adcoms or through your personal statement a one-time, arbitrary test score than a trend over an extended period of time (like low GPA and lack of experience).
In your case, your GPA and experience more than overcompensates for a less than stellar GRE score. Especially in public health, your experience is weighed a lot more heavily than test scores. Of course, if you still feel uncomfortable about your score and don't mind shelling out the $160 and extra studying..feel free to take it again with the understanding that 1) Your score may not increase that much or not enough to make a difference in the minds of the adcoms and 2) Even if your score does increase, that will not guarantee admittance into graduate programs and/or funding. As I said before, my suggestion would be to focus intensely on your personal statement and try to get as many eyes on it as possible to critique it. It is your personal statement which gets you into graduate school---and sadly that is the most neglected part.
