Sandra Anne Mertes
Sandra Anne Mertes, 73, of Waukesha, passed away on October 8, 2017, after a brief illness. Sandy was born in Milwaukee on October 15, 1944, the daughter of George Jacob Mertes and Ona Mary (Fischer) Mertes, who both preceded her in death. She was a devout churchgoer her entire life and was, mostly recently, an active member of the St. William Parish in Waukesha. She graduated from Catholic Memorial High School in Waukesha and went on to earn a Bachelor of Science in mathematics from Mount Mary College (now University) in Milwaukee and a masterís in mathematics from the Catholic University of America in Washington, D.C.
After graduating from CUA, Sandy worked as a software developer and senior computer programmer in the Washington area, before moving back to Wisconsin to care for her parents. In 1978, she joined the international actuarial and consulting firm Milliman in Brookfield and worked there for the rest of her long career, serving as a programmer, a computer resource manager and an actuary. Sandy was a longtime member of the Mathematical Association of America and the Society of Actuaries.
An avid equestrian, Sandy competed in regional Class B hunter competitions on her horse Costello. She was also the proud owner of Reno Runaway, a prize-winning horse on the national Class A hunter circuit. She enthusiastically supported HAWS, the Humane Animal Welfare Society, and made comfortable homes for several foundling cats over the years. Her love of gardening prompted her to attend classes in the UW system to learn landscaping and garden design. Sandy also loved Milwaukee baseball, rooting for both the Braves and the Brewers. She practiced the lost art of scoring every ballgame she attended by hand, the mark of a true baseball fan.
Visitation and a memorial service were held at Shorehaven in Oconomowoc, where Sandy had been residing since suffering a stroke in 2015. Interment was private.
