Conchita del Rosario

Conchita “Chit” Mondejar del Rosario, 82, of Washington, PA passed away peacefully on October 1, 2026 at her home surrounded by family. Born on March 10, 1944, in Butuan City, Philippines to Salud and Ricardo Sr., she later made Belleville, NJ her home.

She graduated with a Chemical Engineering degree from Adamson University and earned a master’s degree in mathematics. In 1973, she emigrated from the Philippines and worked as an Analytical Chemist for 35 years at Hoffmann-La Roche in Nutley, NJ. She was a member of Roche’s bowling team and enjoyed playing and watching tennis.

Shortly after arriving in the United States, she met Chito in Queens, NY and they married in 1979. Chit and Chito had their only son, Jonathan and showed their endless love for each other and him with every sacrifice they made. When she joined her husband in retirement they continued to travel the world. They visited a dozen countries and made countless memories along the way. In 2019, they moved to Pennsylvania to live with Jon and his wife, Jenn. She continued to spoil them, and their friends, with the amazing meals she was famous for. Their dog, Ruthie, also enjoyed endless treats as they sat next to each other every day.

Conchita was also known as a gracious host, non-stop crocheter, devoted caretaker and spouse, an aunt that supported dozens of her relatives either in her home or halfway round the world, and an extremely caring and patient mother.

She was preceded in death by her parents, Salud and Ricardo Sr., her brothers, Rudy, Raul, and Ricarido, Jr. She is survived by her husband Deogracias “Chito” Jr.; son Jonathan (Jennifer); brother George; and many beloved cousins, nieces, nephews, and in-laws.
