Helping You Navigate Treatment Before and After


Navigator Program

Ashley Parnell, RN leads our nurse navigator team and assists new patients diagnosed when they come into the center. Being diagnosed with cancer is frightening. Ashley will help guide patients through the building, answer questions or concerns, and help make appointments.

Survivorship Program

Led by physician assistant Jacob Krause, the Oncology Institute provides survivorship care to help with any issues patients have after treatment. Treatment and therapy can affect a patient’s ability to eat or move around freely. Our survivorship program continues to treat and help patients experiencing these side effects.

Treatment and Diagnosis Tools 

The new institute sets the standard for outpatient cancer care and will allow CHRISTUS Health and Texas Oncology providers to work in a multidisciplinary manner. Patients will benefit from this approach by receiving care from specialists and surgeons with access to the latest technology for treatment and diagnosis, including:

  • Chemotherapy 
  • Advanced Imaging Center with 3T MRI, PET/CT, CT, Ultrasound, Nuclear Medicine and more 
  • Radiation therapy and radiosurgery 
  • Rehabilitation services
