Berkeley VOSH Leadership

Landen Longson, Class of 2025

Faculty Advisor
Elise Harb, OD, PhD, FAAO

Landen is a second-year optometry student and the Berkeley VOSH President. He grew up in Salt Lake City, Utah and earned a B.S. in Biology at the University of Utah before moving to the Bay Area. Landen enjoys trail running, reading, golfing, camping, snowboarding, and cooking. He loves everything that UC Berkeley and the Bay have to offer.

'As I decide where I want to specialize and which mode of practice I want to be involved in, I never want to lose sight of how much of an impact I can make through volunteering.'

Landen plans on utilizing his optometric knowledge and passion as a student and future provider to bring high-quality eye care to underserved communities throughout his life.


Dr. Harb is a Clinician Scientist and pediatric optometrist for myopic children. Her work is focused on better understanding how habitual human behaviors (e.g. near work and outdoor/indoor activity), measured in an objectively and dynamically way utilizing wearable technologies, might play a role in myopia development/progression. Dr. Harb was previously on the pediatric faculty at the New College of Optometry (Boston, 2004-2015) and currently see patients at the UC San Francisco Benioff Children's Hospital (Assistant Professor).

Dr. Harb works in the Wildsoet Lab at Berkeley.

Chiara Miranda, Class of 2025

Megan is a second-year optometry (OD) student and the Vice President of Berkeley VOSH. Megan is from Camp Hill, Pennsylvania and completed her undergraduate degree in Biological Sciences at Clemson University. Megan first became involved in VOSH as an undergraduate volunteer in June 2019 when she assisted the VOSH Connecticut chapter, led by Dr. Matthew Blondin, in operating a free optometry clinic in Emporia, Virginia. She subsequently joined Dr. Blondin at VOSH’s annual trip to San Juan Del Sur, Nicaragua in January 2020 and again in January 2023. Outside of her studies and leadership role with VOSH, Megan enjoys hiking in Tilden Regional Park and the UC Berkeley Botanical Garden.


Chiara Miranda is a 2nd year Optometry student. She graduated from UC Davis in 2020 where she studied Neurology, Physiology, and Behavior (NPB), with a minor in Human Development. Before attending Optometry school, she worked at a private practice in Pleasanton, CA, where she started interacting with patients in and out of the exam room and learned about the many administrative tasks that are necessary to keep a practice running.

As VOSH Treasurer and Fundraiser chair, she plans fundraising events and oversees the club’s funds. In her free time, she enjoys trying new restaurants, taking ballet and group exercise classes, and crafting items like candles or stickers!


c/o 2026 President-elect
Mai Nguyen, Class of 2026

c/o 2026 VP-elect
Vickie Kuo, Class of 2026

Mai Nguyen is a first-year optometry student and President-elect for Berkeley VOSH. She attended San Francisco State University (SFSU) where she received her Bachelor of Science degree in Biochemistry. During her time at SFSU, she worked as an optician and volunteered at the Loving Eye project mission in Vietnam.

Mai’s upbringing in Vietnam and her experiences as an immigrant in the U.S. have nurtured her fierce passion for supporting and advocating for communities that have been historically underrepresented, underserved, and vulnerable. Through her pursuit of optometry and vision science specifically, Mai hopes to promote awareness on eye care among these marginalized communities, ultimately helping them to “see” a better and brighter future.

In her free time, she loves to spend time with her family and her two dogs - Max and Malika. She enjoys hiking, playing video games and watching movies.


Vickie Kuo graduated from UC San Diego with a Bachelors of Science in Human Biology and a minor in Law and Society. She is the VP-elect for Berkeley VOSH. As a first year, Vickie wanted to join VOSH and attend Berkeley VOSH’s Nicaragua trip, because she is passionate about being involved in health equity and providing vision care to underserved communities.

In her spare time, she can be found long-distance running, drawing frogs, or color coding her planning binder.

Early Humanitarian Efforts

Berkeley Optometry has a long history of providing humanitarian eye care to underserved populations. Services to local Bay Area populations began in the 1920s, continuing uninterrupted to the present day. The first international project took place in 1968–69 when optometry student volunteers traveled to Tijuana, Mexico for Christmas and Easter vacations under the auspices of Project Concern, a nonprofit organization headquartered in New York and operating healthcare clinics in New Mexico, Appalachia, Hong Kong, and Vietnam.

In 1989, students established our Berkeley chapter of VOSH and conducted their first chapter mission when volunteer students and clinicians traveled to the Philippine island of Negros Occidental, where they screened approximately 3,000 patients. The success of these international eye-care projects set the stage for efforts in humanitarian vision care that continue today. Berkeley Optometry VOSH missions include visits to Guatemala, Nicaragua, Ecuador, Mexico, Kenya, and Vietnam.

Berkeley VOSH in Narra
In 2018, Berkeley VOSH traveled to the municipality of Narra, on the island of Palawan, where they saw ~2,200 patients in five days of vision screenings. Students performed retinoscopy and refractions, evaluated for medical referrals, and dispensed free glasses that were collected from friends, family and other donors before the trip. Day 1 was at an elementary school, day 2 at a small village, and the rest of the days they set up at the office of the mayor of Narra.
