Diane Langlois — Interventional Radiology Patient Navigator
As a courtesy to our Interventional Radiology patients, Portsmouth Regional Hospital provides the services of a Patient Navigator, Diane Langlois. She serves as a proactive guide to help you “navigate” all the necessary information from the professional and hospital resources that will make your journey to recovery more understandable and positive. Diane is here to help obtain your medical information, schedule consultations, schedule and educate patients prior to their procedures and plan follow-up care. She does the “leg work” that could delay treatment by assisting patients in obtaining medical records from other facilities, making timely appointments for tests and procedures and hopefully increasing patient satisfaction. And, she is just a phone call away. The Center for Interventional Radiology at Portsmouth Regional Hospital has a menu of greater than 60 procedures that we offer our medical community for their patients. If you have any questions please call Diane at 603-433-5285. Our office is open Monday through Friday from 8:00 am to 4:30 pm.
