I got my MPH at SDSU (epidemiology concentration) 2 yrs before I started school. It was definitely a benefit, as it exposed me to a lot of interesting research, and I think it helped me stand out a bit during the application process. If you get the chance, i say go for it. It can only help you become a better med school applicant as well as a better doctor!
The MPH is a very valuable degree to have in today's job market -- with or without a medical degree. I'm currently an MPH student and plan to apply to medical school or graduate school in clinical neuropsychology next summer. Coming into public health, I had mixed expectations. Now that I am almost halfway through the program, I am really glad to have pursued public health. It is a very interesting and multifaceted area with enough opportunities and variety to tickle pretty much anyone's fancy.
I'm currently a dual degreer.... DO/MPH.... Several students at DMU are in the dual degree program or are currently taking courses in the Division of Health Management to consider doing a DO/MPH or DO/MHA.
I, most definitely agree, that the extra training will help me help my future patients....
