Legal Experience That Stands Out

Mark’s healthcare practice includes extensive experience in litigating cases involving rights and liabilities arising under medical provider contracts, disputes over claims and billing methodologies and policies, disagreements arising out of the acquisition and valuation of managed care companies and healthcare providers, and challenges to auditing processes.

In his employment law practice, Mark has served as trial counsel for corporations, state and locally funded public entities, and individuals. He has successfully litigated cases involving allegations of gender, age, race, and disability-based discrimination, and retaliation claims attendant thereto; cases asserting violations of the Family and Medical Leave Act; and cases asserting wrongful termination based upon the exercise of First Amendment rights, including politically motivated firings. He has also served as trial counsel on behalf of both corporations and individuals in cases involving employment non-competition obligations, the enforcement of other aspects of executive employment contracts, and in enforcing the respective rights and obligations under ERISA in connection with employee medical, severance, and disability benefits.

In litigating complex commercial cases, Mark’s experience also encompasses matters involving mass data breaches, and claims arising under the federal Computer Fraud and Abuse Act, and corresponding state statutes prohibiting unauthorized computer intrusions.
