Our Eye Doctor

Eye care professionals specialize in understanding how the human eye really works, as well as diseases and conditions that affect your vision – many of which do not have obvious symptoms. Eye doctors know how age and risk factors affect vision over time for young and old, and they understand the benefits and features of corrective lenses including eyeglasses and contacts.

Our Brownsville optometrist takes the time to explain the results of your eye exam, describe your options and listen to your eye care needs. Because maintaining good eye health is an ongoing partnership, we encourage you to ask questions and share your health information, which could be vital to monitoring, diagnosing and treating potential vision problems.

“I was prescribed glasses when I was in second grade. I remember seeing the leaves on the trees for the first time. In school I enjoyed studying math and science. Solving problems is both a challenge and a rewarding endeavor. My desire is to help people see their very best with glasses and/or contact lenses.”
