The students work side-by-side on a daily basis with our practice physicians where they are involved in numerous clinical tasks, including taking patient histories; documenting in the medical record; explaining and assisting with treatments and surgical procedures; collecting and preparing biopsy and lab specimens; educating patients regarding diagnoses, treatment options, prescription medications and procedures, and more!
Amongst the goals of the internship is to provide an opportunity for students to further confirm their career path in medicine, develop the clinical skills with patients that are integral to the successful physician and experience teamwork and communication skills vital to providing medical care, all while adding an experience we believe will make them that much more attractive a candidate for medical school admission.

Sinai, The Commonwealth Medical College, Georgetown University, Rush Medical College, University of Massachusetts and Chicago College of Osteopathic Medicine.
