If you check out the American College of Nurse-Midwives website (American College of Nurse-Midwives
) they have a list of programs that will license you to be a certified nurse-midwife, including programs that have RN-to-MSN options. Here's a list: Midwifery Education Programs
There aren't any in MA. The closest one is at SUNY Downstate Medical Center in Brooklyn.
MGH's program does not allow you to become a CNM. They have an RN-to-MSN program to allow you to become a nurse practitioner, but the closest thing they have is women's health. Theoretically, you could get your MSN in women's health and become a women's health nurse practitioner, then complete a post-master's certificate in midwifery allowing you to become a CNM. Baystate Medical Center has a post-master's in midwifery.
Another option is East Carolina University, Georgetown University, or Frontier Nursing University. All of them have completely online midwifery programs. They set up clinicals in your home state.
