OUR PRACTICE

H. Ivan Orup, Jr., DMD, MMSc, and his associate, Ivy Chen, DDS, MMSc, are specialists in Orthodontics and Dentofacial Orthopedics. They each completed a rigorous three-year graduate orthodontic training program at the Harvard School of Dental Medicine after earning their dental degrees. As orthodontists, they are uniquely qualified to manage tooth movement (orthodontics) and guide facial skeletal development (dentofacial orthopedics).

Dr. Orup and Dr. Chen are supported by an experienced clinical staff that includes Certified Orthodontic Dental Assistants and Clinical Aides. In addition, the helpful and efficient administrative staff facilitates many aspects of patient care. Each patient is important, and each of our employees works conscientiously to uphold the practice’s ideals.

If you are considering orthodontic treatment, you can schedule a new patient exam. During this exam, Dr. Orup will evaluate your bite, discuss potential treatment options, and answer any questions you may have. There is a small fee for this exam.

Our Mission


With a high degree of professionalism, dedication, and enthusiasm, we strive to provide exceptional orthodontic treatment to adults and children. We seek to deliver this care with the utmost attention to detail and a genuine concern for each patient.
