I've worked with both of those practices as a doula and I feel that the midwives in the practice try hard to support women for VBAC. However, the most consistently positive experiences I have had supporting women for VBAC is with the UofM midwives and with the midwives at Henry Ford West Bloomfield. Beyond how the practices feel about VBAC and the relationship that the midwives have with the physicians that work with them, the hospitals where both of these practices work have functioning telemetry units (St. Joe has telemetry, but it is a different brand and very cumbersome and buggy -- I think Providence Park in Novi has telemetry too but the midwives work more frequently at Providence Southfield, which doesn't) and so the requirement for continuous monitoring ties you down less. In theory, it is even possible to have a VBAC waterbirth at UofM because they can let you wear the telemetry unit underwater.
