Sandra was a graduate of Dunkirk High School class of 1964. Sandra graduated from the former Brooks Memorial Hospital School of X-Ray Technology in December 1966, which began her career as a registered X-Ray technician. This began a career which saw her working in various medical fields as an X-Ray technician and as a dental assistant. Sandra also worked in various other positions throughout her working career, including the Regent Theater and Tops market. Sandra was also a licensed Real Estate Associate for the former Block Realty.

Sandra enjoyed watching the Buffalo Bills and NASCAR, listening to classical music and Neil Diamond. She also enjoyed knitting, crocheting, and crewel work in her younger days.
