Doctor Hung D. Mac attended San Jose State University, where he graduated with a Bachelor of Art degree in Biochemistry in 2000. In 2004, he earned his Doctor of Optometry degree from the Southern California College of Optometry. He received Cum Laude honors at both insitutions. Dr. Mac then completed a prestigious Residency in Cornea and Contact Lens at the Southern California College of Optometry, which involved specialty contact lens fitting and management of complex cases, including keratoconus, post-surgical corneas, corneal refractive therapy (CRT), pediatrics and ocular prosthetics. During his residency, Doctor Mac thoroughly enjoyed serving as a clinical instructor to the optometric interns. His clinical experience, as well as the patients he cared for, has inspired him to continue corneal management and specialty contact lens fitting.

During his free time, Doctor Mac enjoys traveling and spending time with family. His internships and medical mission trips have brought him to El Salvador, Salt Lake City and into a rural Navajo Indian Reservation in Arizona. He plans to continue participating in medical mission trips to South Africa and his birth country, Vietnam.
