Dr. Christopher Duma is one of the most experienced neurosurgeon specialists in the field of Gamma Knife​ radiosurgery and brain tumor surgery.

Dr. Duma treats nearly 200 patients per year and because he also performs open, general cranial neurosurgery, he is uniquely equipped to offer an unbiased opinion about the management of any particular problem.

In addition to his work with the Gamma Knife, Dr. Duma is involved with research in gene therapy, genetically engineered cells and vaccines to fight malignant brain tumors. He has also been at the forefront of research in immunotherapy for primary brain tumors and the treatment of Parkinson’s disease.
