Businessman John Vratsinas, dogged last year by the Internal Revenue Service and more recently by the operators of New Jersey home health care services and an Iowa bank seeking to foreclose on two properties, on Friday filed to liquidate his assets under federal bankruptcy laws. Vratsinas listed assets and liabilities of between $1 million and $10 million. The filing would put at least a temporary halt to efforts to foreclose on a commercial building in Norwalk and a property in Clear Lake. Vratsinas also owns a home in West Des Moines. According to the filing in U.S. Bankruptcy Court for the Northern District of Iowa in Mason City, Vratsinas is living in Clear Lake. In 2009, Vratsinas attempted to reorganize the finances of his John Vratsinas Commercial Construction Co. in West Des Moines under federal bankruptcy laws. However, that case was dismissed and a Polk County judge recently ordered the the company liquidated as part of a $1.5 million judgment in a shareholders lawsuit. In addition to the construction company, Vratsinas has been involved with bio-technology startups and human resources companies. He most recently was vice president of operations for Bianco Bio India Pvt. Ltd., where he netted about $5,000 a month in pay between January and May, according to court documents. Vratsinas has cleared about $6 million in tax liens filed in connection with the human resources companies.
