Sandi was born September 7, 1946 in Dubuque, daughter of Jim and Margaret (O’Regan) Cota. She graduated from Wahlert Catholic High School in 1964.

On August 5, 1967 she married Frank A. Ernst. He preceded her in death on October 16, 2012.

Sandi retired from US Bank after working many years as a bank teller where she built meaningful relationships with her customers. She was a life-long member of Holy Spirit Parish. Sandi enjoyed playing cards and being part of her card club, and she cherished visiting new places around the country with her siblings and her own family.

Sandi’s greatest joy was being a mother and raising her three sons. She later treasured spending time with her grandchildren.  Sandi also loved hosting family gatherings where she would prepare many favorite dishes and treats.

Sandi is survived by three sons, Greg Ernst of Dubuque, Brian (Sarah) Ernst of Cedar Rapids, and Brett (Samantha) Ernst of Decatur, Georgia; three grandchildren, Braden, Regan and Theia Ernst; three sisters, Cindy (Pat) Grace, Mary Cota, and Jane (Tom) McLaughlin; a brother, Mike (LeAnne) Cota; sister in law, Karen Kieffer; and many nieces and nephews.

She was also preceded in death by her parents.

The family would like to extend a heartfelt thank you to all of Sandi’s friends and siblings for their unwavering support during her health battles over the past four years. Their love and encouragement have been invaluable during this challenging time. They would also like to thank Hospice of Dubuque, Dr. Andrea Ries, Dr. Eric Engelman and the MercyOne Dubuque Cancer Center team for their care over the years.

In lieu of flowers, donations to Hospice of Dubuque would be appreciated.
