Dr. James T. Sierra –

Dr. Sierra is originally from League City, so he has a special place in his heart for individuals and families who visit him from the area. When it came time to earn his dental doctorate, he chose to attend The University of Texas Health Science Center at San Antonio, which is where he earned his DDS degree. After graduation, he did not rest on his laurels. In fact, he has always remained passionate about the need for continuing education and has completed more than 1,200 hours of advanced training throughout his career. His unwavering commitment has resulted in an impressive achievement as well: he is a Fellow of the Academy of General Dentistry and a Fellow of the International Congress of Oral Implantologists! If that wasn’t impressive enough, he is also a Master of the International Dental Implant Association, and he maintains active memberships in a number of other prestigious organizations.

When Dr. Sierra is not helping his nearby patients with their smiles or honing his skills by pursuing advanced training, he enjoys spending time with his wife, Dr. Crystal A. Sierra, as well as their two beautiful daughters.
