Meet Your Chandler Orthodontists

In 2004, Drs. O El-Hillal and Wil Saavedra founded E&S Orthodontics. The doctors studied together at Temple University’s Maurice H. Kornberg School of Dentistry and discovered that they shared a passion for patient treatments that were extraction-free and face-driven.

Dr. O and Dr. Saavedra practice at our Chandler office along with Dr. Dick Dykman of Bullmoose Orthodontics. Dr. Dykman and his team merged with E&S Orthodontics in 2018 and now offer services in the jointly branded Chandler Orthodontic office.

Below, get to know each of your Chandler Orthodontists.


Dr. O El-Hillal

Known to his patients simply as Dr. O, Dr. O El-Hillal earned his Bachelor’s Degree in Lancaster, Pennsylvania, at Franklin & Marshall College. He went on to study at Temple University’s School of Dentistry, where he earned multiple degrees – a Doctor of Dental Medicine, an MBA, a Master in Oral Biology, and an Orthodontic Specialty degree.

Dr. O is seen as a leader in the orthodontic industry. His work has been published in several professional journals throughout the years. His leadership ability has become real-world leadership as well. He’s filled various leadership roles during his training, including the coveted Chief Resident.

As one-half of E&S Orthodontics’ founding team, Dr. O helped bring forward-thinking, premier orthodontic care to the Valley. In 14 years of practice, E&S has become the Greater Phoenix Area’s leading provider of treatments like Damon Braces and Invisalign.

Dr. O maintains active memberships in the following organizations:

He is also an Invisalign Preferred Provider.

Dr. O is often praised for both his orthodontic expertise and his approachability. He communicates with patients and parents in a laidback style that builds trust and makes each appointment fun and memorable. Outside of work, he spends his time getting active by biking, hiking, running, golfing, and scuba diving.


Dr. Wil Saavedra

A Virginia native, Dr. Wil Saavedra earned his Bachelor of Science in Biology from the state’s Radford University. He earned multiple degrees while studying alongside Dr. O at Temple University’s School of Dentistry – a Doctor of Dental Medicine, Master of Science in Oral Biology, and a certificate in Orthodontic Specialty.

Dr. Saavedra’s two biggest professional passions are learning and new industry technology, two parts of his work that go hand in hand. To provide the best care possible, he remains dedicated to learning about, and using, the latest technological advancements in the orthodontic industry. This interest doesn’t just benefit Dr. Saavedra – it ensures E&S stays at the forefront of local orthodontics and the industry as a whole. As a result, your Chandler Orthodontic office offers innovative treatments like Invisalign.

Dr. Saavedra is also known for his meticulous attention to detail, leaving no stone unturned to help patients achieve their perfect smile.

Like Dr. O, Dr. Saavedra currently maintains memberships in the following organizations:

Beyond work, he spends his time with family, and he enjoys biking, working out, and updating his computer skills.
