Of all her causes, it is the EMS service about which Judge Freier seems most passionate, perhaps because of the ongoing struggle to keep it alive. Ultra-Orthodox women in Brooklyn had tried to form an all-female emergency service since the 1980s, mostly to help women in emergency birthing situations, she said. But it never happened.

Judge Freier pushed for it. In the years that she worked as an attorney in private practice, she signed up for an emergency medical technician course with her mother, who had always told her she could do anything, “unless it’s illegal, immoral or against the Torah,” she said.

When the powerful male-run Jewish ambulance service, Hatzolah, declined to open to female volunteers at her request in 2011, Judge Freier applied for a license for a separate female EMS service, Ezras Nashim. It opened with some 20 volunteers in 2014. When local rabbis were reluctant to support it publicly, her husband went to Israel and filmed himself getting rabbinical approval from senior sages.

Ezras Nashim, she said, is not about being a feminist, but about reclaiming the traditional role of women to help in their own God-given way. It is the same sentiment that drives her other work. “We aren’t saying the men aren’t good,” Judge Freier said. “But there is something different about us just by the fact that we’re women. We are bringing something that you can’t give.”

The service, which she still leads as director, was recently named EMS agency of the year by the city and state emergency medical service councils. Right now, its women respond in their own cars to emergencies, and they help the 911 ambulance dispatched to the scene. But it is now applying for its own ambulance license and in the coming months will face a public hearing at which Hatzolah and other services can object.

Judge Freier is girding herself for the hearing, even looking forward to it. She has been practicing what she will say.

“I want someone to look me in the face and say that religious women can’t do it,” she said, as she drove to court in her minivan. “I want to see who is going to have the nerve to face me and say, ‘Jewish women aren’t capable.’ I feel bad; I am going to make mincemeat out of that guy.”
