The financially struggling Charlotte, N.C.-based C.W. Williams Community Health Center, which primarily serves low-income patients, filed for chapter 11 protection, the Charlotte Observer reported today. Court records show the health center has liabilities of about $1.8 million to its 20 largest creditors. They include Certus Bank of Mauldin, S.C., owed $680,000; the Internal Revenue Service owed $313,000; and Hermosa Construction Group of Atlanta owed $188,000. C.W. Williams’ board Chairman Nelson Adesegha said the decision to file for bankruptcy became necessary because of the center’s “cumulative financial debt” and as the result of recent legal action against the center’s assets.
