The Team


Dr. Magruder grew up locally in Dickinson, Texas and received his undergraduate degree from Texas A&M University. He went on to receive his DDS at UT Health Science Center- San Antonio. Like Dr. Krumholz, Dr. Magruder is very detail oriented and strives to provide his patients with Dentistry of the absolute highest precision and quality; dentistry that is built to last.

Dr. Magruder genuinely cares for each of his patients and treats everyone like family. As a direct descendent of General John B. Magruder, Dr. Magruder discovered that he has an interesting historical connection to the island. General John B. Magruder was a Confederate Civil War General who took back control of Galveston Island from the Union Army during the Civil War in 1863. When Dr. Magruder is not busy in the office perfecting your smile you may find him chasing speckled trout in the Galveston Bay complex.
