Resident of Walnut Creek/Concord

Ricardo Delfino Tonda passed away peacefully, surrounded by his loving family. Born to Eufrosina and Giuseppe Tonda, who immigrated from Torino, Italy, he was a proud first-generation Californian. Ricardo spent his childhood in Crockett, California, and went on to graduate from the prestigious West Point Military Academy.

Following a successful career, he retired from Shell Chemical.

He is survived by his four children: Margaret (Ben), Charlie (Duinseac), Joseph (Corina), and Michael (Dipti), along with eight cherished grandchildren. He is also remembered by his sister-in-law, Linda Tonda, brother-in-law, Wallace Lonsway, and numerous nieces and nephews. He was preceded in death by his beloved wife, Mary, as well as his sister, Enes Lonsway, and brother, Joseph Tonda.

Ricardo had a passion for traveling, particularly to Italy, and cherished moments spent with family and friends.

Ricardo enjoyed attending his grandchildren’s activities including soccer games, piano recitals and birthday parties.

He loved watching classic movies and hosting gatherings filled with laughter. Known for his distinct sense of humor, he made a lasting impact on everyone he encountered.

He found joy in life's simple pleasures, such as black licorice, dark chocolate, movie theater popcorn, and a refreshing vodka martini during dinner outings.

His presence will be deeply missed by all who knew him.
