"Your September 23rd talk [on Impeached] was exquisitely wonderful, well-delivered, with a light touch, and down-right brilliant."

- Rodney Ross, National Archives, Washington, DC

"[Y]our talk was a complete delight . . .  Clear, concise, to the point, your intriguing new slant at understanding convention proceedings, politics, and outcomes drew a large audience and clearly pleased them.  . . .  Of the thirty surveys collected, 26 gave the highest possible rating . . . Asked what they like best, most simply said, 'the speaker,' 'the lecture,' and 'brilliant,' 'lively,' 'factual.'  Asked what they 'liked least,' a couple said 'wished there had been more time.'"

- Linda Hartman, Gunston Hall, Alexandria, VA

"From the capacity crowd to the pre-program press, the program was a huge success on all levels.  We have gotten nothing but positive feedback."

- Stefan Frank, National Constitution Center, Philadelphia, PA

Thank you so much for joining me and my Treasury colleagues for lunch on the first day of the release of your book, The Summer of 1787. . . . I enjoyed our thought-provoking discussion.  It was wonderful to hear your human perspective of our Founding Fathers.
