More About Mary

She defends employers in single-plaintiff and multi-party litigation against claims of discrimination, retaliation, and hostile work environment arising under federal, state, and municipal laws. Mary also defends employers in complex litigation, particularly wage-and-hour class and collective actions brought under the Fair Labor Standards Act and state law. Additionally, she defends employers in administrative proceedings before various agencies, such as the US Equal Employment Opportunity Commission, the New York State Division of Human Rights, and the New York City Commission of Human Rights. Based on her extensive experience, Mary also counsels management on a host of employment-related matters regarding best practices with respect to compliance with federal, state, and local laws.
Mary works with clients to identify their goals and to achieve them as effectively and efficiently as possible, whether handling an early resolution or fighting tooth and nail. She provides practical guidance to her clients that is in line with their goals for that matter, and she works tenaciously to achieve them. Some of her personal favorites include a voluntary, complete dismissal by a plaintiff after she took his deposition over three days, a dismissal with prejudice of a state claim for want of prosecution, and a dismissal of a charge after seven years, numerous fact-finding conferences, and two requests for reconsideration.
