Our Team


The Gift of Sight is led by a small, dedicated team, but it continues to be a success thanks to a growing group of medical professionals and a few others of various professions who join together and donate their time and resources to our domestic and international missions. Without these talented and giving individuals, we wouldn't have been able to examine and help as many people as we have.

Dr. Kenneth Westfield

Chairman of the Board & CEO


After serving in the United States Army (1969-71), Dr. Kenneth Westfield attended and graduated from the Wayne State University School of Medicine in 1976. He then completed his internship at Henry Ford Hospital in Detroit, Michigan, and residency training at the Kresge Eye Institute. In 1980, he founded a private practice in Las Vegas, which has since grown to become the largest full-service ophthalmology center in Nevada. The center includes an ambulatory surgical center, a Laser Refractive Center and an optical shop.

Dr. Westfield is extremely active in his profession and the community. Among his many accomplishments, he served as the founding medical director of the Nevada Eye Bank; was the first to perform refractive surgery in Las Vegas (radial keratotomy); opened the first satellite eye care clinics to serve outlying rural Nevada; was the first surgeon to perform cataract surgery in a freestanding ambulatory surgery center; and was the first to successfully service a large managed care contract, making surgery from an eye doctor in Las Vegas more affordable for plan participants.

Dr. Westfield founded the Gift of Sight in order to realize his vision for a world where treatable yet debilitative eye conditions were addressed in the places of most need. Since its inception, he has been able to help and heal thousands of people in his own community of Las Vegas and the world over who would otherwise not have received the necessary care. In his eyes, this has been the biggest accomplishment of his career.

Dr. Todd Jackson 

CFO & Board Member 

Dr. Todd Jackson was born and raised in Las Vegas. His family instilled in him a strong commitment to community service, which began with volunteering at the local shelter. After attending Brigham Young University, Dr. Jackson spent 6000 serving the people of Guatemala and made a promise that he would do all he could to serve others throughout his life. It was during this experience that he decided to become a medical doctor and surgeon. 


He attended the Medical College of Wisconsin and completed his residency at The University of Texas Health Science Center at Houston, specializing in ophthalmology. Yet he did not want to wait until he was established to continue to serve the less fortunate. He founded Prestige Laser and Cataract Institute in 2011 with a mission statement to feed the hungry, clothe the naked, liberate the captive and care for the sick and afflicted.  He told his staff, “If I can not run a world-class premium business and do charity from the very beginning, I do not deserve to own a business, and I should go to work for someone else.” He attributes the success of his business to this focus on service.

Dr. Jackson also participates in the H.O.P.E. (Helping Other People Everywhere) clinic on a monthly basis, where he provides care on a pay-it-forward basis. Dr. Jackson’s work around the world has helped him to become proficient and confident treating the most advanced forms of anterior segment disease.  He has participated in eye missions in Guatemala and Kenya and is a member of GOS’ Volunteer Medical Team as well as the organization’s leadership. 

Dr. Hon Vu Duong

Secretary & Board Member


Dr. Duong was born in Hue, Vietnam. In 1975, he and his family immigrated to the United States and settled in Virginia. After high school, he enlisted into the US Army.

A graduate of The Pennsylvania State University, he completed his General Surgery training at The University of Virginia Health Science Center; his ophthalmology residency at Howard University Hospital where he received advance training in oculoplastic and microsurgery; and his fellowship in Ophthalmic Pathology at the Armed Forces Institute of Pathology.

Dr. Duong serves as Assistant Professor of Biology at Nevada State College where he teaches Neuroscience, Anatomy & Physiology, Endocrinology and Microbiology. His primary focus as an instructor is that students not only master course content, but are able to apply the knowledge to novel contexts. This focus carries over in his role as the Director of Continuing Education at the Westfield Eye Center. He ensures that our staff continually learns about the latest developments in procedures and treatments for eye diseases. He also mentors the ophthalmology residents that come through our practice.

Dr. Duong has published in peer review journals. He authored Sickle Cell Retinopathy and Basal Cell Carcinoma of the Eyelid chapters in Roy & Fraundfelder's Current Ocular Therapy, 6th Edition and other ophthalmology textbooks. He has lectured at regional and national ophthalmology meetings. Recently, Dr. Duong along with some of his peers published a Case Study manual for nursing students at Nevada State College and nationwide.
