Licensed in Texas since 2004, according to the Texas Medical Board. We show license dates only for the states that publish them in bulk; see which states do. For other states, check the state medical board.

The NPI date is when this clinician registered for a National Provider Identifier, the billing number used on health claims. It is not a license, graduation or board-certification date. NPIs were first issued in May 2005 and became required on claims in 2007–2008, so an early date usually means the clinician was already in practice before then. What an NPI is

Education and training

  • 2001Medical school: University of Texas Medical School at San Antonio
  • 2007Registered with an NPI (national billing number; not a license date) — NPIs began in 2005, so practice likely started earlier

Undergraduate school, residency, fellowship, licensing exams and board certification aren’t in public federal data. Board certification can be confirmed with the certifying board (ABMS member boards for MDs, AOA boards for DOs).

Specialties and state licenses

  • Clinical Cardiac Electrophysiology Physician primary
    TX license L8193 (first issued 2004; active)
  • Cardiovascular Disease Physician
    TX license L8193 (first issued 2004; active)

As reported to the NPI registry. To confirm a license is current, check the state medical board.
