We’re excited to welcome Tiffany Hostert, FNP, to BJC Medical Group Primary Care at Shiloh – Suite 230.
Tiffany was inspired to pursue a career in health care while visiting her grandfather at Barnes-Jewish Hospital and watching the nurses who cared for him. That experience stayed with her and led her to begin her career as a technician in the Emergency Department at Christian Hospital—and, as she says, “the rest is history.”
After several years in emergency medicine, including travel nursing across New Mexico, Texas, and Tennessee, Tiffany returned home to Southern Illinois and took the next step in her career by becoming a nurse practitioner. She soon found her place in family medicine. While she loved her time in the Emergency Department, she was drawn to something different—the chance to build relationships and be there for patients over time, not just in the moment.
That connection is what keeps her coming back. Tiffany enjoys partnering with patients and working through challenges together. “Being healthy isn’t easy,” she says, “and it takes work from both the provider and the patient.” She values that shared effort—and the progress that comes from sticking with it.
And when that progress shows up, she doesn’t hide how she feels about it. “I literally jump for joy when a patient takes their A1c from 10 to 5,” she says. Whether it’s improving numbers, managing symptoms, or simply helping someone feel better day to day, she celebrates those wins right alongside her patients. Just as important are the moments when someone feels heard and understood—when a conversation alone can make a difference.
Tiffany provides primary care for patients of all ages, offering preventive services, wellness exams, and care for both acute and chronic conditions. She has a special interest in treating diabetes, hypertension, obesity, depression, and anxiety, and works closely with patients to create care plans that fit their lives and support long-term health.
Outside of work, Tiffany enjoys her two favorite “R’s”: reading and running. She’s an avid reader—especially romantasy and thrillers—and grew up loving Harry Potter. She also enjoys running long distances (at her own pace) and spending time with her husband, their two dogs, and their young son.
