Toledo Radiation Oncology, Inc. (TRO) is a group of physicians, physician assistants, nurses, radiation therapists and support staff specializing in the treatment of cancer patients with radiation.  Radiotherapy is needed in managing nearly 2 out of every 3 cancers diagnosed, and is one of the three major cancer treatments (surgery and chemotherapy are the others). 

There are TRO treatment facilities and clinics throughout northwest Ohio and southeastern Michigan.  You may access the menu at the left for further information about TRO physicians, locations, and additional business information.  Please feel free to contact us if you have additional questions. 

Our practice has grown in and served this region with radiation oncology services for over half a century. Drs. Gerald Marsa and Steven Zeidner came to Toledo in the mid 1970’s as the area’s first Board Certified Radiation Oncologists, and thus a separate Oncology Division was created within the existing radiology group. The practice steadily grew, and in 2000 the oncologists incorporated as Toledo Radiation Oncology. 

All radiation oncology services are available, including linear accelerator external beam irradiation, 3-D planning, brachytherapy implants, stereotactic radiosurgery, intensity modulated radiotherapy (IMRT), and radioisotope infusional therapies. Today our twelve physicians and staff members take great pride in the care we give our patients, and this is reflected in the favorable reviews they return. 

A diagnosis of cancer can create a great deal of anxiety; we will do our best to help you through this difficult time while providing the current, state-of-the-art cancer therapy.
