Two years ago, I decided to run for the New York State Assembly seat in the 146th District because I believed that the residents of Amherst and Pendleton deserved a representative who could effectively advocate for our community and reflect the values that make our District a great place to live, work, raise a family, and do business. I challenged an entrenched incumbent and won because the voters of the 146th District were ready for positive change. 

I am extremely proud of the things we accomplished in my first legislative session, from early voting, to sensible gun violence prevention measures, to historic climate change legislation. I was particularly proud to have been the prime sponsor of a bill, which was passed by both houses and signed into law, that requires equal pay for substantially similar work and expands the provisions of New York's pay equity statute to persons in all protected classes.

It has been a great honor to represent the people of my home town. I will continue to advocate for high quality, affordable education for all residents, and I will support environmental initiatives to expand renewable energy use, conserve our precious resources, and address climate change. As always, I will support investments in Amherst and Pendleton that will improve our quality of life and bring economic opportunities to all residents. With your help, I will continue to be your voice in the 146th Assembly District.
