It is with profound sadness and heavy hearts that we announce the passing of Dr. Marcus De Geer, a beloved professor and long-time faculty member at Logan University, who passed away on March 19. Dr. De Geer, who served as a professor in the Doctor of Chiropractic program for over 20 years, leaves behind a legacy of dedication, excellence, and passion that will never be forgotten. His untimely death has left a void not only in the academic community at Logan University but also in the lives of countless students, colleagues, and patients whose lives he touched throughout his distinguished career.
Dr. De Geer’s journey to becoming a respected educator and healthcare practitioner is one of immense dedication and passion for learning and teaching. Originally from Stockholm, Sweden, he began his life with a love for classical music. At a young age, Dr. De Geer took up the piano and aspired to become a professional pianist. However, following his parents’ encouragement, he ultimately chose to pursue a career in medicine. His early years as a medical doctor in Sweden were the beginning of a lifelong commitment to improving the health of others.
After relocating to the United States to practice medicine in Chicago, Dr. De Geer found a new calling in chiropractic care after receiving treatment from a Swedish chiropractor for chronic headaches. It was this personal experience with chiropractic care that inspired him to make the decision to pursue chiropractic medicine. His dedication to learning and his drive to help others led him to Logan University, where he completed his chiropractic studies before beginning his teaching career.
For over two decades, Dr. De Geer served as a professor in Logan’s Doctor of Chiropractic program, where he shared his extensive knowledge and passion for healthcare with generations of students. Throughout his time at Logan, he taught courses in Internal Disorders I and II, Obstetrics/Gynecology, Pharmacology/Toxicology, and Dermatology. He was a gifted educator, known for his ability to explain complex concepts in a way that was both accessible and engaging. His students often spoke of his enthusiasm for teaching, his commitment to excellence, and his genuine care for their success.
Dr. Kristina Petrocco-Napuli, a vice president of the College of Chiropractic, described Dr. De Geer as a passionate educator who always strived to ensure that his students received the best possible education, with the goal of helping them become the best practitioners they could be. “He exemplified teaching excellence. He was a wonderful colleague and will truly be missed by faculty, staff, and students alike,” said Dr. Petrocco-Napuli.
Dr. De Geer was more than just a professor—he was a mentor, a guide, and a friend to those who had the privilege of learning from him. He instilled in his students a love for lifelong learning and a deep respect for the value of education. In a 2022 interview for The Tower magazine, Dr. De Geer spoke about the importance of curiosity and perpetual learning. “I’ve always been curious, which is an important aspect of learning. I want to instill a passion for perpetual learning within my students,” he said. This passion for continuous improvement and growth was one of the core values he imparted to everyone he taught.
Beyond his work as an educator, Dr. De Geer’s commitment to his patients and his profession was unwavering. He was deeply respected and admired by his colleagues for his vast knowledge and dedication to the practice of chiropractic care. His unique background as both a medical doctor and chiropractor gave him a holistic perspective on healthcare, which he shared with his students, colleagues, and patients alike. Dr. De Geer truly embodied the ideals of the medical profession—his focus was always on helping others, whether through teaching, patient care, or mentoring his students.
Dr. De Geer’s contributions to the Logan University community extend far beyond the classroom. He was known for his collegiality and his willingness to collaborate with others. His presence was a source of inspiration to many, and his colleagues were constantly impressed by his humility and generosity in sharing his knowledge. He made a lasting impression not just as a professor but as a friend to all those who worked alongside him.
In addition to his professional achievements, Dr. De Geer was deeply cherished by his friends and family. He was a man of great character—compassionate, humble, and always willing to lend a hand to those in need. His students, many of whom were fortunate enough to receive personal mentorship from him, remember him as someone who genuinely cared about their success both in and outside of the classroom. His influence extended far beyond his role as a professor; he became a trusted advisor, a source of wisdom, and a source of inspiration to so many.
