Lewis Rosenberg, M.D., Ph. D.

Lewis Rosenberg primarily sees patients at Ascension All Saints Hospital in Racine, Wisconsin, where he serves as the clinical director of the department.   He is a general radiation oncologist, meaning that he sees patients with many different types of cancer, including breast, prostate, lung, brain, esophagus, colon, endometrial, cervical, as well as many others. He is proficient in all modern radiation techniques including stereotactic radiosurgery, stereotactic body radiotherapy, intensity modulated radiation therapy, high dose rate brachytherapy, and many others.

He has a particular interest in stereotactic radiation, which is typically used for cancers involving the brain, lung, or spine, but can be useful for many other sites as well.

Besides serving as the clinical director of the department, Dr. Rosenberg is a member of several committees including the hospital’s Breast Program Leadership Committee, Ascension Wisconsin’s Integrated Network Cancer Program, and Ascension’s continuing medical education committee.  He moderates the breast, gastrointestinal, and thoracic tumor boards, and currently is the hospital’s radiation safety officer.

He graduated with highest honors from the University of Michigan, Ann Arbor, in 1999, then enrolled in a combined degree program at Case Western reserve University in Cleveland, Ohio, obtaining a PhD in 2006 in Genetics, and an MD in 2007. He finished residency in Radiation Oncology in 2012 at the University of North Carolina, Chapel Hill, serving as chief resident in his final year.  After graduating, he worked within the Duke University hospital system in North Carolina, and then in 2016 moved to Wisconsin and joined Radiation Oncology Associates.

“I am routinely humbled and impressed by the grace and courage with which my patients face their cancer diagnosis and feel privileged to be able to care for them.  I work to provide the best possible care for my patients and will take as much time as needed to discuss their diagnosis and suggested treatment.”
