Not too long ago, Robert Kirsch lost his wife to cancer.In memory of Cheryl Kirsch, he along with his daughter, Bonnie, and grandchildren Alexyss, Hannah and Nicholas had the honors of flicking the switch for the Hospice of San Joaquin’s annual Tree of Lights ceremony.“I don’t know what we would have done without the Hospice of San Joaquin,” Robert Kirsch said. “They did everything to help (ease her pain) during her last month at home. For that, I’ll always be grateful.”Cheryl Kirsch’s memory is represented by one LED energy-efficient bulb along the 60-foot evergreen in front of Doctors Hospital of Manteca, 1205 E. North St.According to Mark Rasmussen, area supervisor for Pacific Gas & Electric Company, it took six of his men an estimated eight hours to install the strands of light colors onto the tree.One 1,200-foot strand consisted of 1,220 bulbs, he noted.The Tree of Lights will be on display through the end of the month, according to Gene Acevedo, Hospice of San Joaquin’s director of community outreach.All told, the Hospice of San Joaquin has seven Trees of Light including the one in Manteca.
