Welcome to Optivus Proton Therapy, Inc.
Proton beam therapy is a proven and highly advanced
form of external beam radiation therapy that holds many advantages over other types of radiation treatment for
some cancers and non-cancerous diseases. 

With proton therapy, patients experience few to no side-
effects; providing a better quality of life both during and after treatment.
For nearly three decades Optivus has been committed to the advancement of proton beam treatment technology. Optivus Proton Therapy, Inc. (Optivus) has THE MOST experience in the proton beam therapy industry.

At the center of that revolution was the engineering team that would later become Optivus Proton Therapy, Inc.
