Jill Christine Senn

Jill Christine Senn passed peacefully on February 10, 2026, at the age of 63.

She was the loving mother of Nicholas Churchill. She was the dear sister of Jackie Jansen (Gary), Chuck (Liz), Linda Lindenberg (John), Richard (Denise), Kathi Helfman (Alan), Mary Guardalabene (Mark), Judi Momberg (Jay), Jeff, and Lisa. Jill was preceded in death by her beloved brother Jon, and her loving parents Lillian and Warren Senn. She is further survived by many adoring nieces, nephews, great nieces and nephews, and many friends including her lifelong dear friend Heidi.

Jill proudly worked many years at Froedtert Menomonee Falls as a pharmacy technician. 

Jill loved the outdoors and would jump into any river, pool, lake or ocean that presented itself. She loved camping and was known to go it alone if no one else was game. Jill loved to read and watch videos from the Sussex library where the kind and helpful staff knew her by name. Jill was smart, fun and thoughtful and she especially loved children. She was generous of her time and gifts to her many nieces, nephews and great nieces and nephews. Jill loved all kids and made youngsters smile wherever she went. Mostly, she deeply loved her son Nick.

We are grateful to Dr. Elizabeth Hopp and staff for their expertise and kindness. We are so thankful for the great care at Riverview Village and Preceptor Hospice.

The family will hold a private celebration of life.

Jill’s charm and dear heart will never be forgotten.
