A prominent Long Island pediatrician was killed when she tumbled out of a moving Airstream trailer — still clutching the door’s handle — and onto an upstate highway during a family road trip over the weekend, according to state police and kin.

Dr. Monika Woroniecka — a 58-year-old married mom and children’s allergy and immunology specialist with Stony Brook Medicine — was in the 2024 silver trailer with other family members when she fell through the door shortly after 3 p.m. Saturday and onto State Route 12E in Watertown in a freak accident, said police and family.

Woroniecka’s husband, Robert, 59, was driving the gray 2019 Ram pickup truck pulling the trailer at the time, according to a press release.

Motorists who witnessed the frightening fatal fall said the passenger-side door of the Airstream flew open, helped by the wind — while the doctor was clutching its handle, police said.

The helpless woman landed on the shoulder of the highway, striking her head.

She was rushed to Samaritan Medical Center, where she was pronounced dead. 

The traffic accident came as Woroniecka and other relatives boarded the trailer for the final 20 minutes of a road trip from Stony Brook, LI, where the family lives, the troopers said.

The victim worked at Stony Brook Medicine since the early 2000s, according to her medical profile.

“She enjoys working with children and their families and developing a long-term relationship with families while guiding them through chronic allergy-related conditions,” the profile said. “Dr. Woroniecka’s native language is Polish [and] draws Polish-speaking families from far distances.

“Dr. Woroniecka likes to travel, hike, exercise, and spend time with family and friends,” the post adds.

Her grieving family acknowledged to The Post on Sunday that the victim was a doctor on the island, as did the state police, but both declined further comment.

Officials at Stony Brook did not immediately respond to a request for comment.
