Don Crossfield retired from teaching full-time three years ago.
And people still can't stop thanking him for his work, and rewarding it.
The former Roseburg High School math teacher (he still subs) recently picked up an award from the Oregon Council of Teachers of Mathematics for his years of making his subject matter crystal-clear to students.
We get a chance to visit with Don Crossfield, and the person who nominated him for the award; Chloe Ruffin was a student, and is now a math teacher herself.
