The most advanced radiosurgery & radiotherapy, delivered with sub-millimeter precision.
Noninvasive treatment for brain tumors, tremor, trigeminal neuralgia, prostate and breast cancer, arrhythmia, and arthritis pain — including therapies offered nowhere else in the world.
The full range of radiation therapy. One standard of precision.
Stereotactic Radiosurgery
Frameless, incision-free ablation of brain metastases, benign tumors, tremor, trigeminal neuralgia, dystonia, and refractory pain.
SBRT / SABR
Five-session ablative radiotherapy with MRI- and PET-guided focal boost — curative intent with organ function preserved.
Ultra Low-Dose Radiotherapy
Precisely targeted anti-inflammatory radiotherapy for arthritis pain — including low back & neck pain from spine arthropathy, a program our medical director helps lead nationally.
The everyday work, held to the same standard.
Most cancer care still calls for standard fractionated radiotherapy, and we deliver the full course of it here. It runs on the same Varian Edge® platform, the same HyperSight™ imaging, and the same planning and quality-assurance discipline as our radiosurgery cases.
Precision equipment doesn't sit idle between complex cases. It raises the floor for routine treatment — tighter margins, less dose to healthy tissue, fewer side effects.
Varian Edge® with HyperSight™
One of the most precise radiosurgery platforms in operation, paired with the fastest cone-beam CT imaging available. Sub-millimeter targeting, virtual cone delivery, and imaging so sharp it changes what can be safely treated.
Led by a physician who wrote the literature.
Evan Thomas, MD, PhD
Radiation oncologist and biomedical engineer. Led the first North American deployment of HyperArc radiosurgery; principal investigator on the phase I/II trial of frameless SRS thalamotomy for tremor; a national leader in low-dose radiotherapy for spine arthropathy and osteoarthritis.
Frequent collaborator with Varian Medical Systems on the technology behind safe, efficient radiosurgery. Major, US Army National Guard — 17 years of service including deployment as a field surgeon.
Research that moves the field.
We don't just deliver the standard of care — we run the trials that define what comes next.
Low-dose radiotherapy for early Alzheimer's disease
Investigating whether precisely delivered low-dose brain radiotherapy can reduce the neuroinflammation implicated in cognitive decline.
