Since Teen Mania has a history of lying about why people leave the organization, we may never know the answer to that question. Personally, I have a hard time imagining that Dave left willingly and voluntarily. He hasn’t announced his next steps and given the fact that he built a mansion across the street from Teen Mania (and in the middle of nowhere) one could surmise he planned on being at Teen Mania a long time.
There was also the talk about being at Teen Mania until our grandchildren joined the program.
At any rate, his house has actually been on the market since March. So make of that what you will.
