Meeting new people from all walks of life and helping them to see the best that they possibly can are what Dr. Cheung enjoys most. She speaks English, Spanish, and Mandarin. She is certified in the treatment of glaucoma. Dr. Cheung is very eager to serve all of your eye care needs and meet whatever challenges may come her way.
