An orthodontist with three decades of experience, Dr. Roman Leung maintains involvement with his field through affiliation with the American Dental Association, the Midwestern Orthodontics Society, the Chicago Dental Society, the Illinois State Orthodontics Society, and the American Association of Orthodontists. Before founding his own firm in 1981, Dr. Roman Leung completed advanced studies in his field. Following graduation from Duke University in Durham, North Carolina, he gained admission to the Loyola University School of Dentistry in Maywood, Illinois. During his time as a student of the DDS program, he held a full-time position at a hospital.

Today, orthodontist Dr. Roman Leung supervises three Illinois offices in Buffalo Grove, Lisle, and Elk Grove, meeting with as many as 40 patients per business day. Fluent in English, Chinese, Mandarin, and Cantonese, he effectively serves a variety of patients. When clients come to Dr. Leung with orthodontic concerns including cross bites, overbites, under bites, spacing issues, and crooked teeth, he works with them to employ the ideal solution. While some opt for traditional or Invisalign braces, others benefit from mini braces, retainers, space maintainers, or behind-the-teeth models. Whatever the necessary procedure, Dr. Roman Leung supports the busy lifestyles of his patrons with available Saturday and evening appointments. Additionally, his firm accepts a comprehensive range of insurance plans to ensure that people receive the care they need at the price they can afford.

When not improving the smiles of his clientele, Leung extends his energy to several other organizations. Serving as the Board Director of a nearby financial institution, he also acts as Board Chairman of his church.
