Dr. Jamieson was born and raised in Madison, Wisconsin. He earned his undergraduate, master’s, and MD degrees from the University of Wisconsin. He then specialized in psychiatry at Vanderbilt University, where he served as co-chief resident in his third year. During his time at Vanderbilt, he studied under renowned psychopharmacologists who became his mentors.

After completing his residency, Dr. Jamieson established both outpatient and inpatient practices, admitting patients to St. Thomas Hospital, Vanderbilt Hospital, and Parthenon Pavilion in Nashville, TN. At Parthenon Pavilion, he chaired the ECT (electroconvulsive treatment) committee for many years and served as the medical director of the Intensive Treatment Program. He also held the position of Medical Director at Parthenon Pavilion on three occasions.

Initially, Dr. Jamieson practiced with Drs. Bracken and Sheridan before being recruited to join Psychiatric Consultants, a large private practice. He treated adult patients and specialized in manic depressive illness during his 25-year tenure with the group.

He was later recruited by Sterling Primary Care to integrate psychiatry into a large primary care practice in Nashville, TN. Dr. Jamieson aimed to reduce the stigma associated with mental illness through this integration.

He also taught primary care residents at the HCA Primary Care Residency Program, giving lectures on the relationship between primary care and psychiatry and introducing them to common psychiatric illnesses.

With a 45-year history at HCA, Dr. Jamieson has worked in both inpatient and outpatient settings and continued his affiliation through Sterling Primary Care. As of August 1, 2024, he joined St. Thomas Medical Group in Nashville, TN, with plans to maintain a close working relationship between psychiatry and primary care.

Throughout his career, Dr. Jamieson has enjoyed treating patients from all walks of life. He believes that psychiatric illness is a form of medical illness and that psychiatric patients deserve the same quality of care as all other patients. He is convinced that this is best achieved in a primary care setting.
