About SRI


By visiting our website, we hope people will leave feeling informed, empowered, confident, and hopeful! Our mission is to provide information that will educate patients, family members, caregivers, and anyone who may be interested in or is impacted directly or indirectly by sarcoidosis.

It is our vision for people to have an understanding of sarcoidosis; to be knowledgeable of its symptoms, diagnosis, treatment, and research initiatives. Our goal is to provide information that will inspire people to make informed and thoughtful decisions that will hopefully enhance their overall well-being, and will result in improved outcomes for a healthy, happy, and vibrant life.

Our Vision

SRI’s vision is enhanced outcomes for superior health, with exceptional physical, emotional, and quality of life experiences for those impacted directly, or indirectly by sarcoidosis.

Our History

The Sarcoidosis Research Institute (SRI) is a non-profit, 501(c)(3), tax-exempt organization. Over the years, SRI has been an advocate for sarcoidosis patients; hosted patient conferences, support group meetings, and distributed educational materials to patients, their families, networks, and support systems. Inspired by her personal challenges experienced as a sarcoidosis patient, SRI was initially founded in 1991 by Paula Yette Polite.

Sarcoidosis Research Institute Board of Directors

Barbara Buford

Barbara A. Buford is a registered and licensed clinical dietitian who retired in 1994 as a Clinical Nutrition Manager at the Memphis VA Medical Center. She is the mother of two daughters, and grandmother of two grandchildren. Mrs. Buford loves her family, and loves to travel to visit with her family.

Mrs. Buford suffered from the symptoms of sarcoidosis from the age of 18, and was misdiagnosed up until the age of 40. During the 22-year period of misdiagnosis, she could not find any doctors who were knowledgeable of the disease. Additionally, patient information and educational resources were non-existent during that time. Upon a definitive diagnosis of sarcoidosis and a treatment plan created by her physician, she was relieved to be able to finally put a name to the numerous symptoms and illness that she had endured. A medical diagnosis of sarcoidosis validated that her symptoms were real; not imagined; that she truly was sick, suffering, and a victim of sarcoidosis. Her path to a proper diagnosis was a difficult journey, and she was even accused of being a hypochondriac because she didn’t look sick.

Based on her life-long experience with sarcoidosis, Mrs. Buford is deeply dedicated and committed to the critical areas of patient education, awareness, and support; which is why she has served on the SRI Board of Directors for 17 years.

Mrs. Buford stated, “I feel truly blessed to have received treatment for this disease, and am currently 83 years old”. She is active in her church, neighborhood watch association, and is a member of Alpha Kappa Alpha Sorority, Inc.
