Sharon was a lifelong area resident and worked for Winona County Public Health Department where over the years enjoyed life-long friendships with her fellow co-workers.  She retired June 2013.

She enjoyed reading, shopping, spending time with family, crocheting, Netflix and popcorn.  Sharon loved to be on the go!  Even with the added weight of her LVAD, which she called Herb.

We would like to offer our heartfelt thanks to all the members of the hospital staff at St. Mary’s who made the last months of our mother’s days comfortable.  We feel better knowing her last months were full of the best possible care.  The kindness of all the nurses, LVAD team, and Palliative Care team to my mother and her family is something we will always treasure. 

She is survived by her three children:  Anthony (Tanya) Koch, Lewiston, MN; Stephanie (Troy) Janka, Owatonna, MN; and Heidi (Dan) Martinson, Medina, MN; eight grandchildren:  Mollie, Maysie, Camryn, Paige, Libby, Noah, Jack and Ella; a brother David Lettner, Milwaukee, WI; three sisters:  Mary (Greg) Bambenek, Winona; Pat Muldrow, Rochester, MN; and Liz (Paul) Kimoni, Champlin, MN; a sister-in-law Cindi Lettner, Winona; nieces, nephews and other relatives.
