As an undergraduate at the University of Massachusetts, Scott Croshier was a student in three courses that I taught. In an email dated December 2, 2003, in which Scott requested a letter of recommendation, he also commented on our interactions.

Dear Dr. Ellis,
I'm not certain how well you remember me, but I took three courses with
you while a math major at UMass (I graduated in '97). . . .
. . .
. . . I do want to take this opportunity to thank you for everything you've
taught me. While it will take a bit of review for me to dredge up the
particulars of differential equations I learned from you, I have always
remembered the lesson that mathematicians have an obligation to society, not
just to science. I now live my life as someone more aware of social issues
than I was as a college student, and I thank you for helping to lead me in
