Marciann Bock, APN

I graduated from the University of Illinois at Chicago with my Masters in Nursing. I am a board certified Pediatric Nurse Practitioner. I am also an adjunct faculty member at UIC at Chicago and function as a preceptor for future nurse practitioners. I have been actively working as a pediatric nurse practitioner for the past 4 years.

I have spent the majority of my career focusing on the health and well being of children at various developmental and socio-economical levels.

I am a compassionate individual dedicated to my career and the patients and families that I serve. My goal to you as your child’s provider is to deliver care that is unsurpassed and be a representative and advocate for you and your child while preserving their autonomy as they grow older.

During my free time, I do baseball with our 9 year old Anthony, tumbling with William, our 5 year old, Dance with Amber (Amber is 4 years old) and with Nikolas, well, we do baby stuff… he is only 15 months old.
