Janice "Jan" Sienkiewicz, age 74, passed away unexpectedly in her home on April 14, 2026. She was born in Bridgeport, CT oldest daughter to the late John and Agnes Grabiec Sienkiewicz. Jan is survived by her sister Judy and her husband Roger Kleinert. She graduated from Cathedral Girls High School in 1969 and went on to Bridgeport Hospital School of Nursing graduating in 1972 and then completed her BSN from Sacred Heart University in 1999. Throughout her nursing career she was an educator, instructor and mentor in Pediatrics/Pediatric ICU, eventually becoming the Head Nurse of Pedi ICU at Bridgeport Hospital.
