How do I get a dr instead?

My dr office has three docs and three midwives. I'm not high risk, so I always end up seeing the midwives. I don't really care for any of them personally. It has nothing to do with the fact that they are midwives- I just really feel like I have to do all the legwork and research and they don't help me if I have a question. I don't want to change practices this late (25.5) but I don't want to have any of them deliver my baby. How and when do I make that clear? In the birth plan? Will that impact how the office handles me in the meantime? I already feel kind of neglected, so I don't want pissing off the midwives to make it worse because I know the docs will prioritize the women who are higher risk. Thoughts? Suggestions?
