Cristina is a civil litigation attorney concentrating her practice in professional liability, product liability, and environmental/toxic tort.  

Before joining GRSM, Cristina gained experience in product liability, where she handled complex discovery matters and worked as national discovery counsel for one of the largest automakers in the United States. Her experience as national discovery counsel allowed her to partner with in-house and trial counsel in state and federal jurisdictions throughout the United States to defend the client by managing discovery responses, including written discovery, discovery dispute resolution, and protecting confidential information used throughout discovery and at trial. She also represented large corporations in toxic tort litigation.

She also focused her practice on professional liability, including medical negligence, where she represented health care networks, physicians, and nurses throughout the litigation process. 

During law school, Cristina practiced as a law clerk with the Medical Prosecutions Unit of the Illinois Department of Financial and Professional Regulation where she gained extensive experience in the regulation of physician licenses. She served as President of the Appellate Moot Court Society and was an active member of the Mary and Michael Jaharis Health Law Institute. She also served as the Managing and Business Editor of the DePaul Journal of Health Care Law.
