Come to a Clean and Safe Dental Office
We take great care of our patients by maintaining a clean and safe dental office. Every instrument is disinfected and kept in a sterilization area. Rooms are sanitized between each patient visit. You can rest assured knowing your safety is a top priority.
Qualified Dental Care
Your confidence in Marshall Dental includes receiving oral care from a qualified dental health team. Our staff is fully trained, certified and skilled in providing the expert care you and your family deserves.
Informed Patients are Our Best Patients
We do not take an autocratic approach to your dental care. Rather, we empower you with adequate information for making informed decisions about what is best for your oral health. Never are you pressured into receiving invasive and expensive procedures without fully understanding your options.
At Marshall Dental, we will walk you through each step, including diagnosis and treatment options. Our focus is on the most conservative treatments, not the most expensive. In conjunction with making oral health decisions, we stay informed about your medical history and any other factors that may contribute to your dental care.
Kid-Friendly Dental Practice
As a family dental office, our philosophy and office system design is family-oriented. This ensures that every member of your family receives personalized care.
Adults and children deserve an attractive and healthy smile. Yet, the needs are different for people of different ages. The professional staff at Marshall Dental in Oak Lawn, IL tailors education, communication and dental treatment to those needs. This ensures that every patient is comfortable and confident about their dental care.

I’m a 1980 graduate of St. Joseph High School in Westchester, Illinois. My formal education consists of both the B.S. degree and the D.D.S. degree at Loyola University—1989. However, I am constantly upgrading my skills in order to remain at the top of my profession and provide the highest quality services.I served as a dentist in the US Army for three years where I held rank of Captain from 1990 – 1993. I practiced general dentistry in my private practice for over 26 years. Since that time, I have worked in a variety of different office settings as a locum tenens dentist to meet the immediate needs of these practices. They included traditional and private practice, public health care, hospital dentistry and corporate dentistry.
