Overall, Samuel Oshana has been very successful in many business areas over many years. He has had success in both Florida and New York, although these days, most of his success has come in Florida. Much of his success in the realm of investment comes from his ability to start up new companies and nurture them to great success, like the time he led the startup and eventual sale of Apex Data Systems, a merchant payment processor that was once related to with First Data Corporation. He was able to nurture that startup and sell the company for a significant return on investment.
Whereas he spent many years as an investment and business advisor, over the past several years, Samuel Oshana has also spent a lot of his spare time following the sports teams in his beloved hometown of Boston. Samuel Oshana is especially fond of his hometown Boston Celtics, a basketball team in the National Basketball Association. There is nothing difficult about being a Celtics fan. The Celtics have the most championships in NBA history, with 17 of them between 1957 and 2008. In fact, between the 1958-1959 season and the 1965-1966 seasons, the Celtics won 8 championships in a row, and 11 out of 13 during the 1950s and 1960s.
