About The Doctor

Meet Dr. Corless

Dr. David Corless graduated with a Bachelor of Science degree in Mechanical Engineering from Brigham Young University in 2003. Leaving Ford Motor Company after 3 years of service as an engineer to pursue a career in dentistry was an exciting move for the whole family.
In 2011, Dr. Corless graduated with honors from Southern Illinois University School of Dental Medicine. Upon graduation, the family was drawn to Texas and could not be happier to be here.
