“I think the most important thing is to listen to the patient. Let them tell their story and give them the time to explain to you what’s really going on. I think that gives me and other practitioners a better sense of how to care for their problem.”

Dr. Baggenstos received his bachelor’s degree from the University of Notre Dame and subsequently his Doctorate of Medicine from Tufts University School of Medicine in Boston, MA. Dr. Baggenstos then completed his general surgery internship and neurosurgical training at George Washington University in Washington, D.C. He also received fellowship training in neurosurgical oncology at the National Institutes of Health. Among his many publications, Dr. Baggenstos has also received multiple clinical honors, including the Integra Foundation Award and Synthes Skull Base Surgery Award for his research in neuro-oncology. He specializes in the treatment of cranial, skull base and spine disorders, with an emphasis on minimally invasive surgical techniques. His professional affiliations include memberships in the American Association of Neurological Surgeons and Congress of Neurological Surgery.
