Our  Medical Practice

Beginning December 19th, 2011, we are slated to be the first pediatric office in Ooltewah, TN.  We have electronic medical records, an in-house CLIA-certified lab, and access to radiological imaging in cooperation with Memorial Imaging Center located just a few blocks away. 


Dr. Tun and Dr. Sanabria round on newborns born at Women’s East Hospital, and at Park Ridge East Hospital since May 17th, 2014.  Any of Drs. Tun and Sanabria’s patients (including newborns) admitted to the Children’s Hospital at Erlanger Baroness campus in Downtown Chattanooga (about 30-40 minutes drive away from Front Porch Pediatrics) have been arranged to be seen by their excellent Hospitalist (in-house pediatrician-staffed) Service so that their patients can receive timely and comprehensive care while admitted there.


We provide the full spectrum of pediatric healthcare (well, sick, preventative, and urgent care) from birth to college.  Procedures offered include immunizations, laboratory services, hearing and vision testing, breathing treatments, minor splinting, wart removal, ear irrigations, laceration repair, removal of foreign bodies, and abscess drainage.
