Bjorn Lobo, M.D.
Dr. Lobo is a neurosurgeon who specializes in the treatment of brain tumors that arise from the base of the skull and the pituitary gland. He also treats patients with brain aneurysms, hydrocephalus, Chiari malformations and spinal disorders.
Dr. Lobo has a very simple philosophy in his medical practice: treat every patient as if they were a family member. He understands that dealing with neurological illnesses is often an uncertain time in an individual’s life and that many of these illnesses can be painful and debilitating. However, good results are often achieved when the patient and doctor work together as a team. Thus, after obtaining a comprehensive history of the illness from the patient, he likes to break down how specific treatments, including non-surgical management, may alleviate symptoms and then makes the decision together with the patient about the best course of treatment. If a surgical course is decided upon, he utilizes the most cutting edge technologies to provide precision care.
Dr. Lobo grew up in Ohio and went to the Northeastern Ohio Universities College of Medicine where he completed the rigorous BS/MD program, which is one of only six programs in the country that accelerates undergraduate and medical school into a six-year period. He then completed his residency in Neurological Surgery at the Cleveland Clinic Foundation, one of the top four hospitals in the country. While at the Cleveland Clinic, he also completed a two-year fellowship focused on the treatment of complex brain tumors arising from the base of the skull. Spurred by his passion to be technically innovative in all aspects of skull-base surgery, Dr. Lobo then completed an additional one-year fellowship in minimally invasive and endoscopic skull base surgery at the John Wayne Cancer Institute in Santa Monica.
Dr. Lobo is currently seeing patients at his offices in Northridge and Valencia.
