During residency, Dr. Offerman performed research projects resulting in oral and poster presentations and publication in the areas of breast, cervical, head and neck, brain, and ocular cancers. She developed expertise in intensity-modulated radiation therapy, high and low dose rate brachytherapy, and stereotactic radiosurgery.  Dr. Offerman joined Radiation Oncology Associates after finishing her training in 2011.

Dr. Offerman serves as the medical director of the Sherman Cancer Clinic at Elmbrook Memorial Hospital. She has developed the brachytherapy and radiosurgery programs at this center, with the help of an outstanding team of physicists, dosimetrists, therapists, and nursing staff.

“I became a radiation oncologist to utilize cutting edge technology along in order to treat patients’ cancers in the least invasive and most effective way possible. The ability to develop long term meaningful relationships with patients and their families and provide them with support and care during a trying time in their lives makes this vocation particularly meaningful to me.”
