Find a Doctor Disclaimer
“Find a Doctor” is operated by Lifespan and includes all physicians who are on the medical staffs of Lifespan-affiliated hospitals, without any charge to them. Selection is based upon your needs and preferences. Search results will first present, in alphabetical order, physicians employed or contracted with Lifespan or its affiliates, followed by an alphabetical listing of physicians who are in Lifespan’s network of affiliated providers. At the end of that initial list, you can access an alphabetical listing of community physicians with privileges at Lifespan hospitals. All physicians in Find a Doctor have the opportunity to have a picture or video posted on the site. Neither the order of physicians, nor the presence or absence of a photo or video, in Find a Doctor is intended to reflect any preference, priority, or recommendation by Lifespan. Find a Doctor search results are also not based on the volume or value of referrals to Lifespan or its affiliates from any listed physician. Users are free to select their physician of choice from among all Lifespan-affiliated medical staff physicians.
