Thank you both for your input. One of my goals was to try and not make too many assumptions going into my PhD since that caused many headaches when working towards my Master's degree, and in the last few days I've begun to wonder about my assumption that my professional clinical experience will be of benefit. Okay, in fairness, as I approach my upcoming interview at my first choice school I've found myself self-generating all kinds of doubts, many of which are unfounded I know.
Fortunately I have been using time at conferences to start some networking and my current supervisor is super connected so he's been a good resource to know who would be a good fit for me. My top school choice may not bring very much prestige, but the person I want to work with seems to be a really good fit as an advisor for me.
