When faced with the task of choosing which field of medicine he wanted to study, Dr. Brian Darnell wanted it all. Brian loved delivering babies and taking care of mothers, but he also loved the excitement of Emergency Room medicine.

In addition, he wanted to add a holistic aspect to his practice. After weighing his options, he realized that Family Medicine offered him the ability to care for whole families, and still work in the Emergency room. He then chose to be a D.O. (Doctor of Osteopathic Medicine) because it offers a more holistic way to practice medicine. Osteopathic Medicine is a specialty medical school training that takes the structure of the body into consideration in treating patients.

In addition to Obstetrics and Family Practice, Dr. Darnell provides manipulation of the spine, cranial manipulation and muscle therapy to help patients live healthier and more vigorous lives.
