Oscar E. Barrera passed peacefully on Saturday, March 28, 2026, embraced by the warmth and love of his family.

A dedicated professional, Oscar devoted twenty-five years of service to Exxon, displaying commitment and diligence throughout his career.

Following his retirement, Oscar, alongside his beloved wife of forty-two years, Eva Elena “Elenita” Barrera, embarked on a new venture, founding and operating CareStat®, a business that continues to flourish, embodying their shared spirit of enterprise and care. In 2016, the couple made their home in Kingsville, Texas, where they delighted in the company of their neighbors and engaged joyfully with the community around them.

Oscar’s passion extended beyond his professional and entrepreneurial pursuits. He harbored a profound love for hunting, cherishing the many excursions shared with family, friends, and peers that enriched his life with camaraderie and treasured memories.
