Treatment Team

Your chemotherapy will be managed by team of highly trained medical professionals, including but not limited to physicians, physician extenders, oncology certified nurses, clinic assistants, and a financial counselor.

  • Medical oncologists will manage your cancer treatment by evaluating, providing chemotherapy and coordinating any additional cancer treatments, such as radiation therapy. Our medical oncologists have completed an additional 3 years of oncology specific training called fellowship and are Board Certified in both Internal Medicine and Medical Oncology.
  • Physician extenders work directly with the physicians on a daily basis in a collaborative manner. The physician extender works with the physician in the diagnostic work-up of patients, manages symptoms, provides education to patients and families, and assists them in coping. Providing these valued services facilitates the physician’s ability to focus on the technical aspects of patient care, thereby promoting quality patient care. Through the use of physician extenders, we are able to keep our patients on schedule with their treatments when their regular physician is otherwise unavailable. We utilize the physician extender between physician visits for continuity of care.
  • Oncology certified nurses are responsible for all aspects of administering chemotherapy and other IV infusions and injections necessary for patient care. They also provide patient education and telephone management of patient symptoms by interfacing with the providers to ensure patients receive a timely response to their questions and concerns. Oncology nursing certification validates that nurses have met stringent requirements for knowledge and experience and are qualified to provide competent oncology care.  Our oncology certified nurses have broad general oncology knowledge so they can more confidently and effectively address the complex needs of patients with cancer throughout the course of their illness.
  • Clinic assistants prioritize timely and efficient patient flow. The clinic assistant works with the provider to schedule return patient visits, appointments and procedures with other providers, and lab and chemotherapy appointments. They facilitate the connection of patients to resources within the clinic and throughout the community.
  • Financial counselor is a resource that can help patients access specific programs designed to provide financial assistance to help with the payment of out-of-pocket amounts for chemotherapy medications ---amounts such as deductibles, co-pays, and coinsurance. The financial counselor also utilizes cost-sharing Foundations to help those who are under-insured and Pharmaceutical Companies to provide assistance for the uninsured.
