Provider Bio down arrow

Dr. Patricia Lillis is a radiation oncologist, a physician who specializes in radiation for the treatment of cancer. She spent 32 years of her career with the United States Army as an oncology clinician, physician training program member and clinical researcher. She spent one year as a hospital commander in Iraq. After completing her military career, she took about a year in temporary practice locations to find the ideal place to practice.

She gained a fond appreciation for the residents of Wisconsin through one of her temporary assignments with Marshfield Clinic Health System in Rhinelander.

"The Health System is the perfect setting in which to practice medicine in these changing times in health care," Dr. Lillis said.

Dr. Lillis’ father was also in the Army, so she spent much of her youth in Europe. She decided at age 10 that she wanted to be a physician. "I went into Oncology because those patients are such wonderful individuals," Dr. Lillis said.

She earned her medical degree at the Medical University of South Carolina in Charleston and completed her residency in internal medicine and a fellowship in hematology and oncology at Brooke Army Medical Center in San Antonio, Texas. She completed training in radiation oncology at the University of California in San Francisco and is triple board-certified.

She enjoys outdoor activities like hiking, biking, kayaking and local winter sports.
