People here keep referring to age. I don't think it's age per se. I think JW is focused on experience, which can be a function of age. But she is right, dr d has fewer years of experience, and when she went through the CV, it surprised me a little compared to the vast knowledge she displayed on direct. However, her academic/educational background and training seem very impressive, and she is current on the science /protocols behind evaluation. She also seems to have moved very (unusually) quickly into managerial/supervisory capacities, which is interesting.
She knows her stuff, and is very confident. But I'm surprised most others didn't notice a perceptible change in demeanor once Juan was done and JW got up to bat. I felt immediate vibes, like a "prickliness" from Dr d. Nothing like the flagrant and bizarre behavior of ALV, but a definite attitude, which is not the end of the world as she's still extremely credible. But I found that bit of attitude disappointing, and hope it's gone today, especially when they "get into it" on substantive issues (if JW can get to any).
Did no one else notice?
