John Di Leonardo is an anthrozoologist and president and executive director of Humane Long Island. He has successfully led campaigns to stop numerous animal circuses, rodeos, and exotic animal acts from New York City to the North Fork and has stopped the slaughter of thousands of Long Island’s wildlife. John is a New York State Licensed Wildlife Rehabilitator and formerly a “Nuisance” Wildlife Control Operator. He holds a Master of Science in Anthrozoology from Canisius College and a Bachelor of Arts in Psychology from Siena College, as well as a graduate certificate in Jain Studies from the International School of Jain Studies in India.
John formerly served as the Senior Manager of Grassroots Campaigns and Animals in Entertainment Campaigns for PETA, the largest animal rights organization in the world. During his tenure, he led PETA’s Animals in Entertainment Campaign through groundbreaking victories such as the closure of Ringling Bros. and Barnum & Bailey Circus after 146 years, the Iditarod dogsled race slashing its purse by a half million dollars, and SeaWorld announcing the end of its sordid orca breeding program and its circus-style dolphin shows. He also restructured PETA’s International Grassroots Outreach and Action Teams into a new division called Grassroots Campaigns, supervising a team arming activists throughout North America with tools for effective campaigns, and overseeing the Grassroots Protests, Action Team, and Vegan Mentor Program within this new department. Through the launch of PETA’s Action Leader program, he helped introduce the concept of strategic campaigns to activists around the globe.
Previously, John managed day programs on Long Island for people with developmental disabilities and drove the Horseless eCarriage, a humane alternative to New York City’s cruel horse-drawn carriage industry.
John has been honored to receive awards from the New York State Humane Association, the Humane Society of the United States, People for the Ethical Treatment of Animals, In Defense of Animals, and the Suffolk County SPCA, as well as the distinction of being named Mr. February in Rescue Men USA‘s 2016 Calendar. He is a recipient of the Compassion Awards' inaugural Gandhi Award and the National Goose Protection Coalition's inaugural Golden Goose Award.
JULIANA DI LEONARDO
Vice President of Arts & Humane Education, Board Vice President
Juliana Di Leonardo is vice president of arts & humane education for Humane Long Island and a team leader for our animal rescue response team. She holds a Bachelor of Arts in Visual Arts with a minor in Education from Dowling College. She is the owner and head instructor of Ahimsa Arts: teaching yoga, ballroom dance, and kindness to students of all ages.
Juliana is also a New York State Licensed Wildlife Rehabilitator, swim instructor, artist, model, and Reiki Master Practitioner.
Whether it’s teaching humane education yoga classes, preparing presentations for schools and congregations, or catching injured or abandoned birds with her bare hands, Juliana’s warm heart, creative flair, and endless dedication have not only refined Humane Long Island’s humane education efforts but also grown our animal rescue operations exponentially.
Juliana's advocacy for animals exploited by the fashion industry was credited in the 2021 documentary The Face of Fashion is Fear—where she appeared body-painted as victim of the cruel down feather industry—and was recognized by PETA with a "Hero for Coyotes award" following the announcement that luxury outerwear company Canada Goose went fur-free. Juliana appears uncredited in the documentary Real Fur and is a regular contributor to The South Asian Times regarding animal protection and environmental issues.
As a leader of Duck Defenders' New York response team, she and John were featured in an episode of A&E's Rescue Cam removing fireworks duct-taped to a goose.
