Meet our doctors:


Catherine Earl O.D.

Optometric Physician

Dr. Earl is originally from NW Ohio. She graduated from Colorado State University with her Bachelor of Arts Degree and received her Doctor of Optometry from Ohio State University. Dr Earl’s previous experience brings a wide range of specialties to our practice. She has focused training in ocular disease management and fitting specialty contact lenses is one of her areas of expertise. Her professional affiliations include the American Optometric Association (AOA), the North Carolina State Optometric Society, and maintains a local membership to the Piedmont Optometric society.

In her free time, Dr. Earl enjoys snow skiing and spending time with her husband and two children.


Amanda Barker-Assell, O.D.

Optometric Physician

Dr. Amanda Barker, a North Carolina native, completed her B.S. in Biology at The University of North Carolina at Chapel Hill followed by her Doctorate of Optometry at the University of Alabama at Birmingham. Her training at the Northern Navajo Medical Center in New Mexico focused heavily on ocular disease management and treatment while also fostering a deeper love for travel and mission work.

In 2004, Dr. Barker, along with her husband, opened Advanced Family Eye Care in Denver, NC. While she treats patients of all ages, pediatric care and vision therapy has become a primary emphasis. In 2009, she opened SightWork, a vision therapy clinic to more comprehensively manage conditions such as strabismus, amblyopia, traumatic brain injury, and vision related learning delays.

Mission work, both domestically and internationally, is a personal passion for Dr. Barker. Involvement in humanitarian efforts led to the adoption of her eldest child which has been one of the greatest blessings in life. She has had the opportunity to travel to various under-served countries providing eye care along with other humanitarian efforts. Because the needs of her immediate community also weigh heavily on her heart, she has developed various community service projects through her private practice to help individuals close to home.

In her spare time, she loves to read, exercise, work in the community, travel and spend time with her husband and two children.

He then opened Advanced Family Eye Care in Denver, NC in 2004 with his wife and partner Dr. Amanda L. Barker-Assell. He is an active member of the American Optometric Association, NC State Optometric Society, and Denver Rotary Club.
