Ernest Rivas Peña, of San Antonio, Texas, went to be with the Lord on August 29, 2026.

Born on April 27, 1948, in San Antonio, Texas, Ernest lived his life with strength, determination, and a deep sense of loyalty to those he loved. From January 7, 1969 to January 6, 1971, he proudly served his country as a United States Marine, carrying with him the values of honor, courage, commitment, and devotion to duty.   He received the following medals and ribbons; National Defense Service Medal, Vietnamese Campaign Medal with device, RVN Cross of Gallantry with Palm and Frame, Vietnamese Service Medal with 1* and the Navy Achievement Medal with "V."

His service as a Marine was an important part of who he was, and he earned the respect of those who served alongside him. He remained proud of his service and the brotherhood he shared with fellow Marines.

Ernest was a devoted husband who cherished the years he shared with his beloved wife, who preceded him in death. Though widowed, he continued to carry her memory in his heart and remained deeply loved by his family and friends, who will forever cherish the memories they shared with him.

He continued to his Federal Service working at Kelly Air Force Base as an Equipment Specialist and later transferred to Corpus Christi Army Depot where he retired in 2017 as a Pre-Shop Analysis Examiner, working on the T700 and T55 Engines.

He was preceded in death by his beloved wife, Elvia Mendoza Peña, and parents Guillermo Valencia and Ofelia Rivas Peña.

He is survived by his son, Xavier Peña, and siblings Terri, Melissa, Louise, and Ed Peña.

Ernest will be remembered for his kindness, humor, strength, generosity, independence, and love of family, as well as for the lasting impression he made on the lives of those fortunate enough to know him.

He answered the call to serve his country, and he will forever remain a Marine.

Semper Fi.
