About Dan
Dan has a sophisticated, national commercial litigation practice focused on complex business disputes tried in federal and state trial and appellate courts, and in arbitration. His technical background includes managed care and healthcare litigation, employee benefits litigation, consumer fraud, bad faith, employment discrimination, corporate disputes and dissolutions, and class actions.
Among his areas of concentration, Dan has extensive experience in the health care industry. He routinely handles managed care disputes and counsels health plans and commercial payors on underpayments, medical necessity denials, experimental treatments, recoupments, coding audits, non-reimbursable line item charge denials, and related billing issues. These matters often involve in- and out-of-network providers and are frequently resolved through arbitration before the American Arbitration Association (AAA), American Health Law Association (AHLA), and JAMS.
