Alas, very sad. My parents, on the advice of a "tree guy" also had our beloved monkeypod killed. The "tree guy" made three grand and our neighborhood lost a treasure. We never figured ou how to replace that heirloom, planted a ficus which was a total mistake. It's gone now, too.
Try starting one from seed because they grow quickly, but most people including my parents don't have the patience. Good luck!
