Dr. Craig Pope, 50, of Kirkwood, Mo., was charged with 15 felony counts Tuesday and was jailed in lieu of a $1 million cash-only bond, the St. Louis Post-Dispatch reported.
St. Louis County police Sgt. Adam Kavanaugh said investigators executed search warrants for Pope's home and his family medical practice in High Ridge, seizing computers. He said additional charges were possible once the computers hard drives were analyzed.
The newspaper said authorities allege Pope had sexual contact with multiple family members under age 16 between 1986 and this year.
Investigators were trying to determine whether he had inappropriate sexual contact with anyone through his medical practice, the Post-Dispatch said.
"Because of the access, it does make it a greater concern," Kavanaugh said.
Pope was charged with two counts of possession of child pornography, two counts of sodomy, four counts of first-degree statutory sodomy, three counts of second-degree statutory sodomy and four counts of incest.
The case has been presented to the U.S. Attorney's office in St. Louis for potential federal charges, Kavanaugh said.
