Kathleen Miller Obituary, Cause of Death – Coopersburg Community Mourns Beloved Kate at 57

The Coopersburg, Pennsylvania community is mourning the loss of Kathleen “Kate” Miller, who passed away peacefully on July 26, 2026, at the age of 57 after a courageous battle with Frontotemporal Dementia (FTD) and Primary Progressive Aphasia.

Kate’s passing leaves an immeasurable void in the lives of her family, friends, former student‑athletes, colleagues, and the countless individuals she inspired throughout her remarkable career dedicated to service, leadership, and empowering others.

Born on November 15, 1968, Kate approached life with resilience, compassion, and an unwavering belief in the goodness of people. Following her diagnosis in 2020, she and her family faced every challenge with courage, embracing each day with love, hope, and gratitude despite the difficulties brought on by her illness.

Known affectionately as Kathleen, Kate, Katie, Mills, Coach, or Kate‑Kate, she was a devoted wife, loving mother, and trusted friend. Her infectious personality, candid sense of humor, unwavering strength, and genuine kindness made her someone people naturally gravitated toward. Those closest to her remember her fierce love for her family, her uplifting spirit, and her ability to make everyone feel seen, valued, and supported.

Kate shared 32 years of marriage with her husband, Todd B. Miller, and together they raised two children, Michael C. Miller and Sara M. Miller, who were the center of her world. She cherished being not only their mother but also their confidante and best friend.

A woman of deep faith, Kate served as a Eucharistic Minister at St. Joseph’s Church in Limeport, where her commitment to serving others reflected the compassion that defined every aspect of her life.

Her influence extended far beyond her family through an extraordinary career in athletics and education. Kate served as Head Women’s Lacrosse and Soccer Coach and Senior Woman Administrator at Bryn Mawr College, Head Women’s Lacrosse Coach and Assistant Men’s and Women’s Soccer Coach at Moravian College, Athletic Director at Southern Lehigh High School, and Executive Director of the Miracle League of the Lehigh Valley. In every role, she became a mentor who believed in the potential of every student‑athlete and colleague she encountered.

Before inspiring others from the sidelines, Kate distinguished herself as an exceptional athlete. At Pennridge High School, she competed in basketball, boys’ soccer, and girls’ lacrosse before continuing her athletic career at Temple University, where she helped win a National Championship in lacrosse. She earned All‑American honors in 1990 and held the NCAA women’s collegiate record for the fastest goal scored at the start of a game—just nine seconds—for nearly two decades. She also played a pivotal role in establishing Temple University’s women’s soccer program. In recognition of her achievements, she and her championship teammates were inducted into the Temple University Hall of Fame in 2012.

Kate’s passion for developing future leaders extended beyond athletics through her mentorship of young women in leadership programs, including what is now the Snell‑Shillingford Symposium at Bryn Mawr College. Her lifelong commitment to expanding opportunities for women in sports continues to leave a lasting legacy.

She is survived by her husband Todd; her children Michael and his fiancée Elisabeth Gunshanen, and Sara; her siblings Christopher Clemmer, Colleen Savage, Maureen Carman, Eileen Cunningham, Brendan Clemmer, and Megan Baum, along with many extended family members, friends, former players, and colleagues. She was preceded in death by her parents, Henry and Sarah (Walsh) Clemmer.

A private visitation for immediate family and close friends will be held on Friday, July 31, 2026, followed by a Memorial Mass at 11:00 a.m. at St. Isadore Catholic Church in Quakertown, Pennsylvania. In lieu of flowers, the family requests donations to the Penn Frontotemporal Degeneration Center Gift Fund to support research into Frontotemporal Dementia.

🕊️ Kathleen “Kate” Miller’s cause of death was complications from Frontotemporal Dementia and Primary Progressive Aphasia. She will be remembered as a beloved coach, mentor, leader, and friend whose legacy of compassion, faith, and service will continue to inspire generations.
