Meet The TeamTrillium Dental



Our Dental Philosophy

Our dental philosophy begins with the belief that state-of-the-art dental technology should go hand-in-hand with a comfortable and relaxed atmosphere.

Our passion for dentistry extends beyond the work itself. From the time that you set foot inside of our doors until the time that you leave, we strive to make your experience as convenient and stress-free as possible.

Located inside the Huntington Center and opposite the State Capital in Downtown Columbus, Ohio, our elegantly designed, paperless dental office utilizes the most modern tools and technology available, while also providing a host of personalized amenities.

Our Dental Mission

At Trillium Dental, we aim to blend comfort and precision in a way that makes you confident every time that you come by for a dentist visit.

Going to the dentist doesn't need to be the stressful experience many expect it to be. Precise, quick, and comfortable dental service is the future of our industry. So come by our dental offices in the heart of Downtown Columbus, and let us show you how our philosophy at Trillium Dental and your needs align.
