Meet the 2020 On-site Team

Meet some of the people who help keep our wheels turning (literally and figuratively).

Our Optometrists

David Gibson

David Gibson OD

Chief Medical Officer and Doctor of Optometry

Dr. Gibson is a native of North Carolina, a graduate of Southern College of Optometry in Memphis and has been practicing for over twenty years. For nearly fifteen years, he ran a successful practice in Cary, North Carolina but in 2016, he transitioned from the traditional brick-and-mortar model into the startup world of mobile Optometry. Dr. Gibson established 2020 On-site’s operations in Atlanta in 2016, and was promoted to Chief Medical Officer in 2018. In addition to his responsibilities of CMO, Dr. Gibson still sees patients in Atlanta and is instrumental in ensuring that all patients receive quality eye exams and an outstanding customer experience.

Kalah Burchfield

Kalah Burchfield OD

Doctor of Optometry, Boston

Dr. Burchfield is originally from east Tennessee. She graduated with a B.S. from Tennessee Tech University and a Doctorate from Southern College of Optometry in Memphis. She began her career in a private practice in Tennessee before relocating to the Boston area. Dr. Burchfield enjoys spending free time with her energetic puppy and traveling.

"I love that 2020 On-site makes eye care as convenient as possible. We get to provide comprehensive eye care to patients, and they get the opportunity to keep their eye health a top priority without ever leaving their office." 


Katherine Harkins OD

Doctor of Optometry, Boston

Dr. Katherine Harkins grew up in a small town in Wisconsin and attended college at the University of Wisconsin-Madison, where she earned her BS in Biology. She was drawn to the East Coast to attend optometry school at The New England College of Optometry in Boston and fell in love with the city. After earning her Doctorate in Optometry, she spent the next several years in private practice where she enjoyed caring for patients of all ages, providing comprehensive eye care in both English and Spanish. Dr. Harkins likes to travel, try new foods, and meet new people. She also loves her sports teams and luckily rarely has to choose between cheering for her Wisconsin and New England teams!

“I love the atmosphere in a 2020 On-site mobile vision clinic. The team is excited to bring convenient healthcare to our patients, and we work hard to make sure our patients have fun on board, while also receiving top of the line care.”

Jonathan Pena

Jonathan Pena OD

Doctor of Optometry, Boston

Originally hailing from southeast Wisconsin, Dr. Pena relocated to Massachusetts to attend the New England College of Optometry, right here in Boston. Soon after receiving his Doctorate of Optometry, he began his optometric career providing eye care at a private practice in Cambridge. Then, in 2017, Dr. Pena joined 2020 On-site with a mission to advance eye care accessibility and patient care throughout the state. He graduated from Marquette University with a B.S. in Biomedical Sciences in 2008. Dr. Pena is a major sports fanatic and loves his Green Bay Packers almost as much as his two children.

"Since joining 2020 On-site, I have had the opportunity to see patients all over Massachusetts; patients who may not have had an examination in 10+ years. Coming from a private practice where patient retention was a point of emphasis, 2020 On-site has made it accessible and as easy as possible for patients to have eye exams every 1-2 years, as recommended. 2020 On-site has allowed me to See All Patients of MA Differently"

Debi Sarma

Debi Sarma OD

Doctor of Optometry, Boston

Dr. Debi Sarma is a residency trained community health optometrist.  She has built a career around vision health education, and is passionate about improving access to vision care for those in need. Dr. Sarma has a Bachelor of Science degree from the University of Waterloo, as well as a Doctorate degree from the New England College of Optometry. She is a seasoned lecturer on disease topics and loves connecting with people to talk about innovation, culture, and leadership in healthcare. 

"Improving access to care, especially to under-served communities in need, is a deeply rooted passion of mine. What drew me to 2020 On-site was the commitment we have made to Boston Public Schools. When kids see better, they perform better in school and have a stronger opportunity to succeed. It is my hope that these visits help improve the quality of life of the children we see, and also serve as an opportunity for young minds to connect with positive role models in the healthcare field so that they can see differently, and think bigger about their future dreams and aspirations."
