Dr. Testa is a bit of a chip off the old block! Her father, Dr. Ronald Testa, has practiced Pediatric Dentistry for over 35 years.

She earned a DDS from the University of Illinois at Chicago College of Dentistry in 2007 and went on to pursue her postdoctoral training in pediatric dentistry there.

Her masters thesis project "Complications of Oral Intubation in Premature Infants with and without Stabilizing Devices" was presented at the 64th Annual Session of the American Academy of Pediatric Dentistry. It was also presented in Barcelona at the International Association of Dental Research 2010 General Session & Exhibition. Her work has been published in the Journal of Pediatric Dentistry!
