Dr. Leanne Trang Nguyen founded iSight Family Eye Care in 1999. She received her Bachelor of Science and Doctorate in Optometry from the University of Waterloo in 1994.  In the same year, she obtained her licensure to practice Optometry in the State of Pennsylvania and there she completed a 1-year Residency program at the Pennsylvania College of Optometry in Philadelphia where she supervised third and fourth-year Optometry students while expanding her clinical knowledge in glaucoma, macular degeneration, cataracts and retinal diseases.  She is committed to providing the highest standards in patient care. She is fully trained in laser surgery management and is an Affiliate Doctor of the TLC and the Bochner Eye Institute laser centers. 

Dr. Nguyen counts herself as one of the lucky ones who gets to do what she loves each day.   Her patients are her extended family.  She feels privileged to play an important role in helping to protect the future well being of her patients’ eyes by providing total wellness eye exams that include nutritional and lifestyle recommendations.   She is also energized to help her young patients control their nearsightedness through the application of various myopia management modalities.

Outside of the office, you might find her jogging, hiking or biking on the many trails of Mississauga and the GTA.  She also enjoys travelling like a local, playing the piano, learning new languages, and spending time with family and friends.

Dr. Jonathan Khanh Dinh obtained his Doctor of Optometry and Bachelor of Science from the University of Waterloo. During his final year of study, he completed an Ocular Disease and Therapeutics Externship at Eye Associates of Pinellas in Florida where he had the opportunity to manage many patients with diseases such as glaucoma, macular degeneration and diabetic retinopathy. Dr. Dinh is a proud member of the College of Optometrists of Ontario, Ontario Association of Optometrists and the Canadian Association of Optometrists.

Dr. Dinh became an optometrist because he wanted to provide every patient the ability to achieve their goals through vision. He has fond memories of playing volleyball in highschool and if it were not for his contact lenses, he would never have been able to play on his school team. Although seeing clearly is important, a person can still struggle with vision even if they can read the 20/20 line. Hence, Dr. Dinh’s clinical interest lies in pediatrics, binocular vision and vision therapy. Whether it be through glasses, contact lenses or vision therapy, Dr. Dinh would like to help his patients grow and discover their true potential.

When Dr. Dinh is not seeing patients, he enjoys staying active with snowboarding. If you ever visit Mount St. Louis or Blue Mountain, you may catch a glimpse of Dr. Dinh boarding down the slopes (or falling on his bum). He also enjoys spending his free time singing and playing the guitar. Perhaps you may even hear him sing along to his favourite songs in the clinic. Otherwise, you may find some of his music online.

Dr. Dinh takes pride in providing his patients thorough eye examinations. He looks forward to meeting all his patients and cannot wait to contribute to each and every one of their lives through vision.

He completed his Primary Care rotation in Brantford where he developed his ability to perform thorough comprehensive eye exams for people of all ages and tailoring to the needs of his patients.

During his spare time, Dr Bui loves to play the piano and alto saxophone and is currently learning other instruments like the ukulele and accordion. Outside the office, he enjoys biking, playing volleyball and playing basketball whenever given the chance.
