The Montebello clinic was the first clinic to begin treating patients, under the care of Dr. Thropay in 1980.  Since then, it has outgrown itself and now houses Therapy, Nursing, Physics and Transportation.  The Nursing Unit includes an executive assistant, a clerk, two medical assistants, and two RNs.  The Therapy Unit has a chief radiation therapist, two radiation therapists and two radiation therapy aids.  The Physics Department is directed by a full time Medical Physicist, Albert Mesa.  The physics department includes an array of high tech treatment planning computers, a dosimetrist and a computer technician.  The Transportation Unit, headed by Thomas Meneses, includes five drivers.
Not only are we the first of the BOI clinics, we were also the first freestanding facility in America to implement IMRT in 1997; the first of all of radiation therapy centers in L.A. County and the fourth in the state of California.  The swift application of new treatments has enabled us to treat cancers that were otherwise untreatable and it has limited many side effects thus offering a better quality of life for cancer patients.  
Dr. Thropay is the main physician in Montebello; Dr. Rha and Dr. Chuang also service patients here.  In addition to IMRT we offer 3-D conformal and conventional radiation treatments.  Additionally, we address other patient’s needs such as support for medication, for those who are in need of financial assistance, early detection and clinical research programs. We encourage you to contact us for an appointment.  Services are provided in English, Spanish, and Chinese.
