What Our Patients Say

5 star review by martha


Wonderful!! Always wonderful!! It's been 30 years now since we first came to Big Smile Dental. Every visit is always met with kind and courteous help at the front desk. I always feel very cared for and the care is gentle. I live 40 miles away from Logan Square now, but I still travel to see Dr. Siegel because I trust him as a person and as a professional. I trust my family to his care!
