Olga S. Cavalier, 77, of Monaca, passed away peacefully on Monday, October 27, 2025, in a local skilled nursing facility after spending the past year receiving care.

She was born in Germany in 1948, a daughter of her loving Ukrainian parents, Walter and Sonia (Klaban) Sluzynsky. Olga immigrated with her parents to the United States at the tender age of two and found her family’s new roots in Aliquippa.

Olga was a proud graduate of Aliquippa High School, class of 1966. Her thirst for knowledge led her to further her education at Robert Morris University, laying the groundwork for a successful career. Olga devoted many years of service as a medical secretary at Sewickley Hospital, where she supported the medical records and pathology departments with unwavering dedication.

Her personal life was filled with love, though marked by the loss of her dear parents and her spouses, Joseph William Rusnak and Anthony Cavalier. Olga’s legacy continues through her beloved daughter Jen Rusnak, her caring sister Joanna (late Dana) Holland, her brother Steve (Connie) Sluzynsky and fiancee Robert Davidson. She was an aunt to Meghan Sluzynsky Dellas, Mark (Tammy) Holland, Christopher (Kate) Holland, and Steven Sluzynsky, and great aunt to William and Christopher Holland, along with her great-niece Grace Holland.

Olga’s passions extended beyond her professional endeavors. She was an avid sports fan, her enthusiasm spanning from the thrill of football at every level to the excitement of March Madness basketball. In her later years, Olga discovered a love for golf, embracing the sport with the same zeal she brought to all her pursuits.

Olga was a devout member of St. Peter and Paul Ukrainian Catholic Church in Aliquippa and a member of the St. Helene Guild of the church. She was also a member of the Monaca American Legion Post 580 Auxiliary and the Beaver Valley Sportsman Club, where she formed many lasting friendships.
