Margaret Pollard Marks, M.D., a respected pediatric endocrinologist whose life and career were defined by academic excellence, compassion and a deep commitment to children living with endocrine disorders and diabetes, died on August 29, 2026, from complications related to diabetes. She had recently celebrated her 37th birthday.
Born on July 15, 1989, in Birmingham, Alabama, Margaret was the daughter of Charles and Tanya Marks and grew up in a close-knit family alongside her four sisters, Marty, Morgan, Amanda and Hastings, affectionately known as “Lucy.”
Margaret spent the first decade of her life in Mountain Brook, where childhood was filled with family traditions, sports and summer activities. She and her sisters spent time at Lake Martin, competed on the Mountain Brook Country Club swim team, danced at Steeple Arts and played soccer with their father serving as a coach. Family vacations to John’s Island and summers at Camp Skyline and Camp Greystone also became cherished parts of her upbringing.
She attended Highlands School in Birmingham before the family moved to Oak Mountain, where she continued her education at Oak Mountain Middle School and Oak Mountain High School.
After graduating from high school, Margaret chose a path of her own, attending Furman University in Greenville, South Carolina, on scholarship rather than following her older sister to the University of Alabama. She entered college already determined to pursue medicine and quickly distinguished herself academically and socially.
At Furman, Margaret majored in Neuroscience and Spanish. In the summer of 2008, she participated in a Spanish-language immersion program at Universidad Internacional in Cuernavaca, Mexico, where she also worked as an infirmary assistant at an orphanage. She was a member of Alpha Delta Pi sorority and volunteered with the Furman Panhellenic Council.
Following completion of her undergraduate degree, Margaret began medical school in 2012 at the University of Alabama at Birmingham’s Heersink School of Medicine. She graduated summa cum laude in 2016 and earned her medical degree shortly before turning 29.
Her intellectual ability was widely recognized by professors and classmates, many of whom considered her among the brightest people they had encountered. Despite her accomplishments, those closest to her remembered Margaret as remarkably approachable, humble and quick-witted. Her humor became a defining part of her personality among friends and colleagues, matching the intelligence and clinical skill she brought to her work.
Margaret completed her pediatric residency at Children’s of Alabama and later remained at the institution for a fellowship in Endocrinology and Diabetes. Her leadership and expertise soon earned her the position of Chief Fellow.
After completing her fellowship, she accepted a position as an Assistant Professor in the Division of Endocrinology and Diabetes at Children’s Hospital in Birmingham. Her professional life placed her at the center of caring for children and families facing complex medical conditions, including diabetes.
Patients and colleagues remembered Margaret not simply for her medical knowledge but for the warmth, humor and humanity she brought to every interaction. Her ability to combine clinical excellence with genuine compassion made her deeply respected within the medical community and among the families she served.
Margaret’s death from complications of diabetes carries particular poignancy given her professional dedication to endocrinology and diabetes care. Her passing leaves behind a medical career that, although far too brief, made a meaningful difference in the lives of patients, families and colleagues throughout Birmingham.
She is survived by her father, Charles Marks; her mother, Tanya Marks; and her sisters, Marty McElrath and husband Chris, Morgan Marks, Amanda Walker and husband D.K., and Hastings Marks and Connor O’Brien. She is also survived by aunts Margaret Porter and husband Kip and Diana Arnold and husband Thomas; uncle Steve Sanderson and wife Darlene; nephews Wyatt McElrath and Porter Walker; nieces Holland Walker and Hastings O’Brien; and several cousins.
Margaret was preceded in death by her uncle Randy Marks and by her grandparents, Charles Caldwell and Jeanne “Mimi” Marks, and Clay and Amanda Sanderson.
Her family reflected on the heartbreaking loss of a woman whose intelligence, humor and compassion touched countless lives. In remembering her, they referenced Don McLean’s “Vincent,” invoking its imagery of a life whose beauty seemed almost too great for the world that contained it.
A private memorial service will be held in Margaret’s honor.
In lieu of flowers, the family has asked that memorial contributions be considered for the UAB Comprehensive Diabetes Center, continuing Margaret’s connection to the field to which she devoted her professional life.
Margaret Pollard Marks leaves behind far more than an impressive medical résumé. She will be remembered as a beloved daughter and sister, a devoted physician, a gifted scholar and a compassionate presence whose brief life carried an extraordinary impact on those fortunate enough to know her.
