He probably has one particular staff person who handles intake of new patients and that person is just trying to get hold of you to get your information started. My experience with intake personnel is that you almost always have to leave a message when you call and they call you back, so you need to keep your phone on you so that next time when they call you can actually talk to them. It isn't about them being pushy or passive-aggressive; it's just that only this one person handles new patient intakes. I've encountered that kind of system with quite a few different specialists offices. In fact, just went through that changing my husband's pain specialist. It can be frustrating initially, but that's just the way they have that new patient intake system setup. Once you get that initial contact made and get that first appointment scheduled (which they won't do until they talk to you and get insurance info, etc.), you will probably have an easier time from then on.
