Oncology
The Area’s Only QOPI® Certified Practice
Welcome to Oncology at Crystal Run. The cancer care we provide locally has been recognized nationally. Crystal Run Healthcare was one of the first 16 community cancer care facilities in America certified by the Quality Oncology Practice Initiative (QOPI®). QOPI® Certification is awarded to practices that meet 24 measures for cancer care, and 17 specific chemotherapy safety standards. This important certification demonstrates the ongoing commitment of our physicians, nurses, and support staff to make a difference in the lives of our cancer patients by achieving the highest standards of excellence for their care.
Our commitment to cancer care stems from our roots. What started as a single-specialty Oncology practice has evolved into Crystal Run Healthcare. At Crystal Run, we know the quality of the care that an oncology patient receives is one of the most important aspects of a successful treatment outcome.
At Crystal Run, cancer care is a multi-disciplinary team approach. You’ll receive coordinated care from oncologists/hematologists, certified oncology nurses, an oncology surgeon, and a nutritionist. Plus, we make it easy to schedule lab work, diagnostic hematology testing, and biopsies, often all in one place because we also know that, when it comes to receiving treatment, comfort, convenience, and peace of mind are key. That’s why Crystal Run’s on-site infusion suites were designed with the comfort and privacy of our patients in mind.
