About Dr. De Simone

After attending the Greenhill preparatory school in Addison, Texas, Dr. De Simone relocated to Southern California to attend college.  In 2004, he began his dental school training at Louisiana State University, earning a Doctor of Dental Surgery degree in 2008.  After graduation, he returned to Texas and entered into general practice where he discovered that his passion in dentistry was in oral surgery and sedation services.  He then decided to focus his career on providing these in-house surgery services for other practitioners.

In addition to his many distinguishing memberships, Dr. De Simone sits on the Board of Directors of the Dallas Academy of General Dentistry and is a Fellow in the Academy of General Dentistry and in the American Dental Implant Association.

Dr. De Simone loves what he does and enjoys being the type of dentist his patients can trust, depend upon, and turn to for their difficult dental problems.  His philosophy is simple -- "We treat your family like you are family."
