It is with great sadness and a heavy heart that we share the news of the loss of long-time Logan faculty member, Marcus De Geer, DC (’01), MD, who passed away on Wednesday, March 19.
Dr. De Geer served as a professor in Logan’s Doctor of Chiropractic program for more than 20 years. Within the program, he taught Internal Disorders I and II, Obstetrics/Gynecology, Pharmacology/Toxicology and Dermatology.
“Dr. De Geer was a passionate educator and healthcare practitioner. He always wanted to ensure that students in his courses received the best information to be the best practitioners they could be,” said Kristina Petrocco-Napuli, DC, MS, DHPE (’23), FICC, FACC, vice president of the College of Chiropractic. “He exemplified teaching excellence. He was a wonderful colleague and will truly be missed by faculty, staff and students alike.”
Early in life, Dr. De Geer was said to have aspired to be a classical musician before deciding to become a medical doctor. Growing up in Stockholm, Sweden, Dr. De Geer took up piano at a young age. He dreamed of becoming a professional pianist, but his parents strongly encouraged him to pursue medicine. After working as a medical doctor in Sweden, Dr. De Geer immigrated to the U.S. to practice medicine in Chicago, where he realized he wanted to pursue a different career.
Considering other professions to help improve the health of others, Dr. De Geer recalled how a Swedish chiropractor had successfully treated his headaches. With a newfound appreciation for chiropractic, Dr. De Geer completed his studies at Logan and began teaching shortly thereafter.
Dr. De Geer was well respected and admired by his students and colleagues. He often spoke about his passion for learning and teaching. In a 2022 interview for The Tower magazine, Dr. De Geer said, “I’ve always been curious, which is an important aspect of learning. I want to instill a passion for perpetual learning within my students. I’m grateful to be at an institution like Logan with such a nice atmosphere to teach alongside extremely well-trained colleagues and instructors.”
The Logan community extends its deepest sympathy to the friends and family of Dr. De Geer.
