Diana P.

Assistant

I have been working as an assistant since 2021. I was interested in dentistry because I admire how people sometimes arrive at the office in pain or not feeling great but then leave feeling happy and with a big smile. The best thing about being part of a family practice is that I meet a patient and within a couple of days, meet the rest of their family.

I was born and raised in Hoffman Estates and In my spare time, I love spending time with BeBe, my 9 yr old morkie, and Loba (wolf), my huskie. My family is my center and being here at Schaumburg Smiles has made me feel at home.
