Hall of Fame / Emeritus

James Little Sr., MD, FAAP

Jackson's first pediatrician, Dr. Little retired in June, 2022 after 50 years in local practice.  (He is pictured above in the Tetons on Rock Springs Buttress, circa 1972.) According to the Jackson Hole News & Guide, "Dr. Jim Little Sr. started his profound tenure in Jackson in 1972 as one of only seven doctors in town.  Each one had a specialty--obstetrics, radiology, surgery--but they all pitched in on emergency calls.

"If Little hadn't settled in Jackson, the landscape of family care might have looked quite different today.  Surrounding communities in Teton Valley, Idaho; Star Valley; and Sublette County still don't have pediatricians.

"'I would see anybody that walked in the door,' Little said.  'Over the years I think that there were a number of kids that, you know, if I hadn't been there and done the right thing at the right time, they wouldn't be here.' He has since treated those kids' children and grandchildren."
