The Rochester Area Vegan Society will host sustainability educator Joel Helfrich as he discusses the Rochester River School at its meeting at 7 p.m. June 19 at Brighton Town Park Lodge, 777 Westfall Road, Rochester.

Helfrich, along with Jericsson Pichardo, founded the River School as a hands-on school on the model of the Harbor School in New York City. The school is scheduled to open for the 2018-19 school year, and will be the first vegan public school in the U.S. For more information, visit rochesterriverschool.org.

There will be a vegan potluck dinner at 5:30 p.m. Vegan means no animal products — meat, poultry, fish, eggs, dairy products or honey — and attendees should bring a dish with enough to serve a crowd, a serving utensil and a place setting for their own dinner. RAVS members are available to help nonvegetarians and others make a vegan dish.

The meeting is free for RAVS members and $3 for the general public. For more information, call 585-234-8750 or visit rochesterveg.org.
