About Jeffrey R. Jacobsen, MD

Dr. Jeffrey Jacobsen is a pathologist Board-certified in Anatomic, Clinical and Hematopathology. His expertise lies in assessing diseases of the lymph nodes, spleen, blood and bone marrow where diagnosis relies not only on microscopic interpretation but also through the use of flow cytometry. Dr. Jacobsen is currently working to update our current flow cytometry capabilities in conjunction with bringing on-line a molecular pathology laboratory to better evaluate pediatric neoplasms. The data obtained from these studies will allow the clinicians to provide the optimal care for each and every patient.
