Dr. Zendejas recognized Dr. Emilio O. Hernandez, DDS for his many years of providing free custom mouth guards to BISD athletes at his own expense on Monday, September 19 in his office.  His daughter, Dr. Alisha Hernandez, is working with her dad to carry on his tradition.  Dr. Hernandez is the first BISD volunteer to be personally recognized.  Plans are to continue recognizing BISD volunteers throughout the school year for making a difference in the lives of our students.    BISD volunteers are the heart of the community.  View more photos.
