Licensed in California since 2019, according to the Osteopathic Medical Board of California. 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. What an NPI is

Education and training

Board certification can be confirmed with the certifying board (ABMS member boards for MDs, AOA boards for DOs).
