Carlos Rene Montemayor Sr.

​Carlos Rene Montemayor Sr., 68 years of age, passed away peacefully on September 16, 2026, surrounded by his loving family after a short illness.

Carlos was born on June 20, 1958, in San Diego, Texas, to Carlos Jose Montemayor and Maria Lopez Montemayor. He was a proud graduate of San Diego High School, Class of 1976. Following graduation, he continued his education at Texas A&I University in Kingsville.

Carlos dedicated 30 years of his life to educating and mentoring young people as the Building Trades teacher at San Diego High School. Throughout his career, he shared not only his knowledge and skills with his students, but also valuable lessons they could carry with them throughout their lives. After his years in education, Carlos embarked on another chapter of his life when he opened The Daiquiri Shak in San Diego.

Carlos truly enjoyed the simple pleasures in life. He loved hunting and fishing and never minded an occasional trip to the casino. Above all, he treasured spending time with his family and friends. Whether sharing stories, laughter, or simply enjoying each other's company, those moments meant the most to him.

Carlos left this world with a deep love and unwavering faith in God. His family finds comfort in knowing that he is now at peace and reunited with his beloved parents and sister, whom he deeply missed.

He was preceded in death by his parents, Carlos Jose Montemayor and Maria Lopez Montemayor, and his sister, Anna Liza Waldrop.

Carlos leaves behind to cherish his memory his daughter, Chandra (Rey) Garza of Alice, Texas; his son, Carlos Rene Montemayor Jr. of San Diego, Texas; his brother, Arnoldo (Tina) Montemayor of Austin, Texas; and his beloved grandchildren, Aidan, John, Maggie, and Carlie Garza of Alice, Texas. He is also survived by numerous nieces, a nephew, extended family members, former students, and many friends whose lives he touched throughout the years.

Carlos will be deeply missed, but the memories he created, the lessons he shared, and the love he had for his family will continue to live on in the hearts of all who knew and loved him.

May his memory forever be a blessing, and may he rest in eternal peace.
