Dr. Kelly is a caring doctor certified by the American Board of Internal Medicine, committed to providing top-notch healthcare with a focus on keeping her patients healthy before they get sick. Growing up in Frankfort, IL, she attended Carl Sandburg High School in Orland Park, then started college at DePaul University in Chicago before transferring to Illinois State University. She pursued her dream of becoming a doctor at Ross University School of Medicine and completed her training with a residency in internal medicine at Advocate Lutheran General Hospital in Park Ridge, IL, where she also welcomed her two beautiful daughters in quick succession.

After finishing her residency in 2020, Dr. Kelly began her career as a Primary Care Physician at Riverside Medical Group in Bourbonnais, IL, where she worked closely with patients and colleagues for three fulfilling years.
