Two Icons of our profession, Anna Pattison and Esther Wilkins, shared a tiny office at Tufts University in Boston. Anna shares this memory about her mentor and lifelong friend

"The greatest lesson I learned from Esther as a young clinician was to always probe first and scale thoroughly to the base of the pocket."
