Doctors

Dr. Toan A. Tran is a therapeutic optometrist & optometric glaucoma specialist born and raised in the DFW area. His dedication and personal commitment to “serving patients first” provides for a thorough, comfortable, and overall excellent experience.

After graduating from the University of Texas at Austin, Dr. Tran went on to obtain his Doctor of Optometry in San Juan, Puerto Rico and is clinically trilingual (English, Vietnamese and Spanish). When Dr. Tran is not in the office, he spends most of his time with his extended family and close friends. He is an avid golfer, plays flag football twice a week, and loves supporting hometown sports teams (Mavericks, Rangers & Cowboys).

Dr. Tran has been in the optical & optometry field since 1999. He started off as a newly hired optician, earning and learning his way through every position within the front office before being accepted into Optometry school. Once he graduated from Optometry School with his doctorate, he knew the only way to fulfill his knowledge and craft was to open up a private practice.

He’s now a proud owner of an on-campus practice at the University of North Texas in Denton. This Denton location allows him to make an immediate educational impact on all students from undergraduate to post-doctorate, employees, and professors of both UNT and TWU in the area. By opening Wink Eye Care in the early summer of 2013, he is able to practice full-scope optometry from all different ages and generations and happily serve the community of Little Elm and Frisco.
