A Connecticut man is pulling double duty on the front lines of the coronavirus pandemic - and he's making a big impact in Westchester.

Marc Mosca is a seventh grade science teacher at Albert Leonard Middle School in New Rochelle. His school was part of the initial containment zone early on in the coronavirus outbreak.

He's now teaching his class virtually and is also a part-time respiratory therapist at White Plains Hospital, where he cares for the sickest coronavirus patients put on ventilators.

He says he is often the last person patients see before they are put under sedation.

"It's heartbreaking because they can't have family in the hospital. It's one of the saddest things I've experienced in my almost 20 years in this field," he says.

News 12 asked him what keeps him going. He says his students play a large role. He also takes pride in the fact that he is making a difference in patients' lives.
