Elizabeth Louise Keith

Elizabeth “Betty” Keith passed away in October 2026 at the age of 90. She was a devoted mother, grandmother, great-grandmother, nurse, musician, and friend. Betty lived with compassion, quiet determination, and a deep commitment to helping others.

Betty was born Elizabeth Louis Zinsmeister in 1936 in Glenshaw, Pennsylvania. She was the first child of Aloyius and Margaret Zinsmeister and grew up with her younger brother, John. Her father was a dairy farmer. The family was rooted in the Catholic faith, and Betty attended Catholic schools, including St. Mary’s School.

When Betty was 14, her family moved to St. Petersburg, Florida. They hoped to find a better life for John, who faced significant physical challenges. Helping care for her brother helped inspire Betty’s lifelong calling to nursing.

Betty was an excellent student. She entered the Mound Park nursing program and graduated in 1957. There she formed friendships that lasted nearly seven decades. The Mound Park nurses stayed close through regular reunions and shared memories. Betty later earned a bachelor’s degree.

During nursing school, Betty met Donald “Don” Keith on a blind date. Don was serving in the United States Coast Guard. They married in 1958 and shared more than six decades together before his passing in 2019.

Betty and Don raised two children, Debra and Mark. Family was always at the heart of Betty’s life. She took great pride in her children, two grandchildren, and two great-grandchildren.

Betty dedicated her career to nursing. She spent 23 years at All Children’s Hospital in St. Petersburg and became a Director of Nursing. Her colleagues respected her skill, leadership, and dedication to patients and families. She taught and mentored generations of nurses. She believed that excellent nursing required both compassion and sound judgment.

Retirement did not end Betty’s work as a nurse. She volunteered with the St. Petersburg Free Clinic, Faith Community Nursing, and other community organizations. She was also involved with the Florida Organization of Nurse Executives and the Tampa Bay Organization of Nurse Executives. She valued the friendships and opportunities to strengthen the nursing profession. Betty often stepped into leadership roles wherever she served. She kept her nursing license until the final year of her life.

Faith remained important to Betty throughout her life. As an adult, she became a devoted member of the Lutheran church. She stayed connected to her congregation as Garden of Peace Lutheran Church became part of Paradise Lutheran Church in Treasure Island, Florida.

Music was another source of joy. Betty sang in choirs and played the piano from an early age. In retirement, she learned the dulcimer and even a little mandolin. She wanted to join Don at the bluegrass jam sessions and music camps he loved. Learning bluegrass was, in many ways, an act of love.

Betty was a nurse wherever she went. Family, friends, and neighbors knew they could count on her. At Mark and Virginia’s wedding in 1987, Mark suffered a deep cut to his hand. Betty pulled a suture kit from her purse and stitched the wound closed. It was a memorable example of how ready she always was to help.

Over the years, Betty cared for neighbors and friends facing broken bones, chronic illness, and the challenges of aging. She offered practical help and worked to preserve their comfort and independence. When the COVID-19 pandemic began in 2020, Betty was already in her eighties. Yet she stepped forward to help administer vaccinations. She knew the risks, but serving her community mattered more. To Betty, that was simply what a nurse did.

Betty also faced serious health challenges, including three battles with cancer. She rarely complained and continued to think of others. Even in her final weeks, she worried about the people who depended on her and whether they would receive the care they needed.

Betty was preceded in death by her beloved husband, Donald Keith. She is survived by her brother, John: daughter, Debra; her son, Mark, and his wife, Virginia; her grandchildren, Jacob and Alyssa; and her great-grandchildren. She leaves a legacy of service, friendship, music, and love.

Betty made a lasting difference in the lives of those she cared for. Nursing was her profession, but caring for others was part of who she was. She gave generously of her knowledge, her time, and her heart.

Rest well, Mom. Your work was well and faithfully done.

A memorial service will be held at Paradise Lutheran Church in Treasure Island on November 21 at 11 a.m.
