Mercyhealth welcomes board certified neurosurgeon

Mercyhealth is pleased to welcome Markus Chwajol, MD, board certified neurosurgeon, to Mercyhealth Neurosurgery Center, 1000 Mineral Point Ave., Janesville.

"As a fourth generation physician, I continue to implement in my practice the principles of ethics and dedication to patient care I learned early in life from my parents and grandparents," said Dr. Chwajol. "My philosophy is to provide compassionate, state-of-the-art neurosurgical care while treating patients as a whole, beyond their isolated brain or spine conditions. I operate on patients, not on their imaging studies. I educate and make sure they are involved in the planning of their own care early. A better understanding of their condition and its treatment empowers patients, which enhances recovery, allowing for a more wholesome healing. I combine 18 years of experience with the utilization of cutting-edge technology and employ the latest, most innovative surgical approaches."

After earning his medical degree at the State University of New York, Downstate College of Medicine, Brooklyn, NY, Dr. Chwajol served a neurological surgery residency at Montefiore Medical Center, Bronx, NY. He then completed a cerebrovascular neurosurgery fellowship at the University of Illinois at Chicago, Chicago. He is certified by the American Board of Neurological Surgery and is a Fellow of the American Association of Neurological Surgeons and a Fellow of the Congress of Neurological Surgeons. Dr. Chwajol is an assistant professor at the University of Illinois at Chicago.

Dr. Chwajol's special interests include:

  • Cerebrovascular neurosurgery, including aneurysms and vascular malformations
  • Brain tumors, including skull base, pituitary and metastatic tumors
  • Functional neurosurgery, including neuralgia and epilepsy surgery
  • Spine and spinal cord tumors
  • Minimally invasive and complex spine surgery

Patients interested in seeing Dr. Chwajol should talk with their health care provider about a referral. For more information, call Mercyhealth Neurosurgery Center at (608) 756-6826.
