Dr. Thomas Marshall, MD
Board-Certified Ophthalmologist | Cataract & MIGS Specialist
Dr. Thomas Marshall is a board-certified ophthalmologist with over 30 years of experience serving Baytown and Southeast Texas. Concentrating on small-incision cataract surgery with specialty lens implants and minimally invasive glaucoma surgery (MIGS), he has performed over 40,000 successful surgical procedures and helped over 227,000 patients achieve exceptional vision outcomes through advanced surgical techniques, personalized care, and a compassionate, patient-centered approach.
What sets Dr. Marshall apart is his remarkable combination of surgical excellence, community leadership, and deeply personal approach to patient care. As a Castle Connolly Top Doctor since 2010, former Chief of Surgery and Chief of Medical Staff at Houston Methodist Baytown, and 25+ year Lions Club member, he has shaped healthcare in Southeast Texas for over three decades. Proficient in Spanish and devoted to his Christian faith, he offers to pray with patients who wish and brings both technical mastery and spiritual comfort to his practice. His philosophy is simple: treat every patient with the care, respect, and attention they deserve.
Beyond his clinical practice, Dr. Marshall has demonstrated a lifelong commitment to service—from earning his Eagle Scout rank at age 14 to leading medical missions to Zambia and Mexico, and spiritual missions to Cuba and Bolivia. His career highlights include several profound moments where early detection of serious conditions in the eye led to life-saving referrals, including spotting brain tumors through imaging and diagnosing a young man with leukemia, allowing him to receive immediate treatment and live a normal life. Dr. Marshall and his wife raised three daughters—all Texas Aggies—and now enjoy spending time with their grandchildren.
