Tania Paoli, Dental Hygienist

Tania was born and raised right here in Illinois! After graduating from Lakes Community High School, she attended the College of Lake County and Wichita State University. In addition to being certified in CPR, she is certified in nitrous oxide and local anesthesia. For her, the best thing about her job is meeting and connecting with others. The instant gratification from cleaning a patient’s teeth and having the opportunity to explain the importance of oral health are two of the many reasons she’s proud to be an RDH!

In her free time, Tania and her husband enjoy hiking, doing family game nights, and cruising around town on their motorcycle. She also likes biking through her neighborhood, watching true crime media documentaries, and spending quality time with her nieces and nephews. Here’s something you may not know about her: she reached her optimal height in fifth grade (5 ft).

Bert Delgadillo, Dental Hygienist

Bert Delgadillo graduated from Harper College as a registered dental hygienist. He was born in Mexico but grew up in the Chicagoland area. His hobbies depend on the season.

He finds biology fascinating and understands the importance of oral health on overall wellness. He chose dental hygiene as a career because it gives him the opportunity to educate and improve patient health one mouth at a time.
