This year, for every customer who has clicked onto this page, Simulia and CST of America will donate $1 to charity. These donations will go to the Greg Hill Foundation in Boston that responds to the immediate needs of families that have been touched by tragedy.

Since 2010, The Greg Hill Foundation has been able to donate $2M to local families in need after such tragedies as the Boston Marathon Bombing and the Las Vegas shooting. The Greg Hill Foundation helps take some of the financial burden off of those who are suffering.
