No good deed goes unpunished

So in July off goes Dr. X to Europe.

Before he leaves and before I had resigned my contract with him, I had provided for him additional doctors to see his patients during his absence, hired a new bookkeeper for him, as well as arranged all of his automatic bank payments, including the payments he had agreed to pay to me for the loan (which was in default) I had made to him and for the balance owed by him to me for products he purchased through my buying group for his practice. 

However during his absence he ordered his bank to stop all the auto payments to me and then on his return begins to tell everyone that I had written checks and withdrawn funds from his account without his knowledge or approval.  So much for truth and honoring ones financial agreements.  Funny thing is that when he was later confronted about these statements at my attorney's office he admitted that he had authorized me to set-up these automatic payments but that he stopped the payments because he knew there wasn't enough money to cover the checks.  I guess that was true because he pulled $20,000 out of his business checking account for his personal use during the month while he was in Europe. How do I know this, his girlfriend and bookkeeper told me.  Obliviously he was more concerned with his month long vacation than for paying his bills.

Unfortunately he hasn't done this just to me. I know of another three vendors to whom he still owes around $20,000 each.  Unfortunately they have not gone after him legally.
