Kathy N. Rosenthal, by Margaret Fox Photography

Kathy N. Rosenthal, partner in Rosenthal & Markowitz, LLP since January 2001, concentrates in the areas of estate planning and estate settlement, trust and will drafting, and residential real estate transactions, working with single persons and both married and non-married couples, with a focus on providing legal support to same-sex couples.

In addition to private practice, Kathy taught Wills, Trusts & Estates as an Adjunct Professor of Law at Pace University School of Law from 1995 through 2013. She is very proud that she was selected Adjunct Faculty Member of the Year by the students in 2002, 2003, 2004, and 2005, after which the award was no longer granted to adjunct professors. Kathy also taught Wills, Trusts & Estates as an Adjunct Professor of Law at CUNY Law School from Fall 1989 through Fall 2001 and she also co-taught a 12-credit Wills Clinic at CUNY Law School from Fall 1991 through Spring 1993. In addition, Kathy taught the Wills component of the BAR-BRI bar review prep course in January 2004 for the February 2004 bar exam.

Kathy is the consummate teacher – she loves to share information and wants to teach her clients about the laws relevant to their matters so that her clients understand their documents and their estate plan.

Kathy has had and continues to have an active professional life outside of the practice as well. Her current community work is more focused than in the past. Kathy serves on only board at present - the Board of Advisors of the Westchester Community Foundation (WCF) .

Kathy’s prior community work was more extensive and bears mentioning, working from the present backwards:

Kathy served on the board of the Estate Planning Council of Westchester County. She also served as a Board Member and Chairperson of the Westchester Public/Private Partnership for Aging Services after finishing terms as Vice Chairperson and Treasurer. Kathy served on the Board of the Westchester Women’s Bar Association Foundation, the charitable arm of the Westchester Women’s Bar Association, for ten years from 2002 through 2012.   She has also served on the Board of the Women’s Enterprise Development Center, Inc., and as a Friend of Gail, the development arm of the Pace Women’s Justice Center which works to eradicate domestic violence.  In June 2003, Kathy finished her second term as President of the Westchester Women’s Bar Association (the “WWBA”).  She previously served as a Vice President and Corresponding Secretary.  While President and for several years thereafter, she sat on the Pace Law School Board of Visitors as the representative of the WWBA. She wrote the SCPA Article 9 portion of the Matthew Bender, Surrogate’s Court Practice, Winter 1986. A strong proponent of continuing education in the profession and the community, Kathy speaks frequently. She was Co-Chair and moderator for the Pace Law School annual Elder Law update for more than 5 years, resigning to make room for “newer blood”.  She volunteers and speaks for the Pace Women’s Justice Center doing community education on estate planning.  From 2008 through 2013, Kathy taught the Pace New Directions program on Wills, Trusts & Estates, to attorneys re-entering the work force.

In prior years, Kathy spoke regularly for the Planned Giving Committee for the Arthritis Foundation, New York Chapter, Hudson Valley Branch until it closed and she won the Volunteer of the Year Award in 2002.  She has lectured on various aspects of estate planning for the New York State Bar Association, the Pace Law School Continuing Legal Education program, the Family Law Center, and for many and varied community groups. Earlier in her career, Kathy volunteered at the Gay Men’s Health Crisis and helped create their Will drafting clinic in 1989, writing forms and supervising other attorneys.

Kathy has been in practice since 1978,  and still very much enjoys the work she does — making order out of chaos and bringing information and comfort to her clients.
