Meet Dr. Ryan O'Sullivan, DDS, MS

Fayetteville local. Founder of Hillside Orthodontics.

Dr. Ryan built Hillside Orthodontics with a simple goal: to provide exceptional, technically precise care without the pressure or upselling common in the industry. As a Fayetteville local, he believes in treating patients like neighbors, running on time, and delivering a hospitality-driven experience that puts your family first.

Common questions

When should my child first see an orthodontist?

The American Association of Orthodontists recommends a first check-in by age 7. This allows us to monitor growth and ensure permanent teeth have enough room to arrive naturally.

Am I too old for braces or Invisalign®?

Never. We design confident smiles for patients of all ages. Modern treatments are more discreet and efficient than ever, making it easy to prioritize your smile at any life stage.

How much does treatment cost?

Every smile is unique, so every plan is custom. We provide transparent, interest-free payment options and work with most insurance providers to ensure high-quality care fits your budget.

Do you offer virtual consultations?

Yes. We value your time. You can start your journey from home with a quick virtual screening before visiting our Fayetteville clinic for a full 3D scan.
