I don't think they have a formal MPH program, but as publichealthr said, they do have a great post-bac and post-doc program. I had a friend who was in the post-bac program (who ended up dropping out because it was just way too much programming all the time), who said that UW would pay for post-bac fellows to get MPHs who stuck around for the second year of the fellowship - a kind of work-study arrangement. The program is still pretty new (I think it started around 2007) but has tons of money from the Gates foundation. If you are interested in metrics (i.e. developing systems measures) and are good with programming (i.e. are ok with spending your whole day programming on sas) you should look into it. Great program and great backdoor way to get into a very competitive MPH program. Keep in mind though that the program is also very competitive. I applied and didn't get an interview but this was last year when I had less than a year of work experience.
