Christy Siemer, BBA, CNMT, RT(N)

Recruitment Specialist
618.457.5200 ext. 67012 |

Southern Illinois Healthcare captured Christy’s heart in 2003, where she began her career with SIH as a nuclear medicine technologist. Patient care has always been a priority for her and she wanted to be able to reach and help more patients than she could see clinically. Christy returned to school and earned a degree in business administration. Shortly afterward she joined the physician relations department as a physician recruiter.

Christy now feels that by bringing the highest quality physicians to Southern Illinois Healthcare she is helping all of the people of southern Illinois, not just those she cared for clinically. Her passion for excellent healthcare right here at home drives her to find the best physicians for SIH. It is very fulfilling for Christy to be a part of the quality and growth of healthcare in southern Illinois.
