Salvatore R. DiDonna passed away Saturday morning, December 20th, 2025.  Originally born in Brooklyn, NY and having lived in Chester, NY for many years, he had spent the better part of the last decades living in Mount Dora, Florida, with his wife Elizabeth who passed away in 2019.  The former President of Swiss American Securities was an amazing husband, father, brother, uncle, best friend, and neighbor to too many to count. He will most certainly be missed.
