Welcome to Our Zelienople Dentist Office

Setting the Standards for Exceptional Dentistry

Our very own Dr. Mark Marion is an award-winning dentist! Since 2011, his peers – other local dentists and specialists – have selected Dr. Marion each year as one of Pittsburgh Magazine’s Top Dentists. Plus, the Pittsburgh Tribune-Review listed him as a bronze winner for top North Hills dentist. And the awards keep coming...not only was Dr. Marion selected as Zelienople Best Dentist and Zelienople Top Periodontal Practice, but also as one of America’s Best Dentists! In addition, Dr. Marion and his staff consistently draw rave reviews from patients.

Since 1986, Marion Smile Center has been providing families in Zelienople and Harmony, Pennsylvania with the finest in dental care. That's when Dr. Mark A. Marion, a third generation dentist, opened his practice and began following in the footsteps of his dad and great uncle.

Dr. Marion has carried on this family tradition to offer you a modernized practice that is dedicated to bringing the latest innovations in dental care to your family. Offering state-of-the-art general, restorative and cosmetic dentistry, our Zelienople dentist combines unsurpassed skill with artistry to create beautiful, confident smiles that are as healthy as they are functional.

As part of your regular dental exam, we screen for oral cancer using tools that can detect the earliest stages of this serious disease. Dr. Marion can also test for and detect periodontal disease using the latest in dental technology, and he can treat cases appropriate for highly effective non-surgical modular treatment.

In addition, every member of your family will receive compassionate and attentive care in a relaxing, welcoming environment. Whether you need a routine cleaning, crowns, veneers, or dental implants, you and your smile are in excellent hands at Marion Smile Center. With your comfort always in mind, we offer conscious sedation for patients who request it.

Caring for you and your family is our number one priority. Our highly skilled dentist and dental hygienists put your well-being first and go out of their way to help you feel at ease. For the number one dental office in Butler County and the North Hills area of Pittsburgh, contact our Zelienople location at (724) 452-4300 or request an appointment online.

This organization supports children’s charities around the world, specifically helping underprivileged kids receive needed dental care. While Coronavirus limited some of the time that we were able to do cosmetic whitening, we still accomplished much together. Besides our existing patients, others from the Zelienople-Harmony community also supported the cause and had their whitening done at our dental office. The Marion Smile Center Team was scheduled to go to Guatemala on a Humanitarian Dental Trip in September 2020. These plans were changed due to Coronavirus. We are aiming to reschedule our trip for September 2021. When we do go, our team will work at a Guatemalan dental clinic and provide dental care for FREE! We will focus on the Q’eqchi communities in the country’s Polochic region, which is located in east-central Guatemala. Through this mission, underprivileged children will ...
