Is Ok to have your first degree in Sociology but I dont think is a smart idea to wonna do a graduate study in this field. My advice is for you to divert your graduate school into Public Health and you can use your sociological underpinnings to really make a difference. Try specializing in social epidemiology of disease and illness with an emphasis in International health. If you graduate in the upper 5 percentile of your class, I can garantee you that the National institute of health(NIH) will pay your way to do your PhD in health economics, International Health, Epidemiology or Biostatistics. If you take this route, it will be the smartest decision of your life. I have a MPH degree in International Health and Im currently stationed in Riyadh. When I come back to the states, I will be doing my doctoral work in health economics with emphasizes in policy implementation.....is how you enhance yourself with what you've got. Research....research..and you will never go wrong. Like previously said by the other authors, learn to write effectively, polish your writing skills and you can make a lot of money....my 2 cent..good luck!
