Services have been set for Samantha Calzone, a Greenwich resident who died in a horseback-riding accident on Monday in Dover, New York.  Services for the Redding native will be held Saturday from 3 to 7pm and Sunday 10am to 1pm at Leo P. Gallagher Funeral Home in Stamford.  The horse Calzone was riding reared for an unknown reason and fell on top of the 23-year old.  In 2014, Calzone was accepted into the animal science program at UConn and joined the equestrian team.  She graduated magna cum laude in 2018. The UConn Equestrian Team posted the following notice about Calzone, “She served as a mentor and a true ray of sunshine to UCET and all people who were lucky enough to know her. Sam was a true horsewoman and loved our sport, and these animals, with her whole heart.”
