My deepest sympathies to Barbara and Justin and the rest of Quentin's family. I came to know and love Q late in his life, but he made an impression. He was compassionate, smart, dedicated, witty, and a great diagnostician and an evidence-based clinician. I am blessed to have called him friend and Barbara my "sister-wife". He fought a courageous battle for such a long time. I'll miss him deeply. May happy memories bring you some measure of comfort in the difficult days ahead. Much love, RonnAnn and Ernie.
