Jenni A.Adams, RN, BSN, OCN
Oncology Nurse Navigator

Jenni A. Adams, RN, BSN, OCN head shotOnce the patient and managing physician team come to an agreement on a plan of care, a patient is referred to Portneuf’s Oncology Nurse Navigator. As a navigator, the primary focus is to assist oncology patients in the following ways:

  • Serve as an essential link between patients and all other care providers within Portneuf Cancer Center and the community.
  • Coordinate treatment planning conferences among various physicians for patient care.
  • Develop concise summaries of the plan of care for use by the patient and their providers (with documentation of the nationally recognized treatment guidelines of such standardized care protocol).
  • Assist patients and their families in understanding the diagnosis, treatment options and the resources available to them during and after the cancer journey.
  • Stay connected with patients and make appropriate additional referrals as needed (i.e., social work, financial advisor, dietitian).
  • Educates patient and families on medications, chemotherapy protocols, radiation therapy, and side effect management.

In short, a navigator partners with patients, families, the Cancer Center team, and community providers to ensure well-coordinated, timely, compassionate care.

Adams received her Associate Degree of Science, Nursing at the College of Southern Idaho in 1993, Bachelor of Science Nursing in 2008 from Idaho State University.

Robb Dye, LCSW, MSW head shotThroughout our lives, each of us face a variety of demands, losses, and challenges that test our ability to cope.

Our oncology social worker can help you and your family:

  • Learn new ways to cope with cancer
  • Manage emotions such as anxiety or sadness
  • Improve communication with your health care team
  • Talk to your family about cancer
  • Find reliable information
  • Find useful resources in your community
  • Manage financial challenges
  • Maximize your existing support system
  • Adjust to illness
  • Work through end-of-life issues
  • Deal with grief and loss
  • Make decisions for future medical care (advanced directives)
  • Face the challenges of caregiving.

Robb Dye has been practicing social work since 1998. He worked in a variety of settings prior to coming to Portneuf in 2008. His education includes a Bachelor’s of Social Work from Idaho State University and a Master’s of Social Work from New Mexico State University in Las Cruces.

CaeDee Astin
Financial Advisor

CaeDee Astin, head shot, Portneuf Cancer CenterMany patients have insurance coverage and I can provide help in understanding the benefits of individual policies. It is best to address financial concerns early during cancer care. If a patient does not have insurance coverage, I can advise of other forms of assistance that may help cover the costs of treatment.
