Former Doctor Who Sold Matthew Perry Ketamine Now Reportedly Working as Uber Driver

A former doctor who sold Matthew Perry drugs before the beloved Friends star’s 2023 death is now reportedly working as an Uber driver.

According to an Us Weekly report published Wednesday, December 10, Mark Chavez — who was once a licensed San Diego physician — suggested he be sentenced to time served with three years probation.

Chavez, 55, pleaded that he “suffered public disgrace” and works as an Uber driver, per the publication. He reportedly surrendered his medical license after being charged in connection to Perry’s death and said that the ketamine he sold to former doctor Salvador Plasencia was not the ketamine that killed Perry.

The former doctor could potentially face up to 10 years in federal prison, according to a previous release from the U.S. Attorney’s Office in the Central District of California.

Chavez, who pleaded guilty in October 2024 to one count of conspiracy to distribute ketamine, has a sentencing hearing on Wednesday, December 17, per the U.S. Attorney’s Office.

The Fools Rush In actor, who openly discussed his issues with substance abuse throughout the years, tragically died on October 28, 2023, at age 54 from an accidental drowning caused by the acute effects of ketamine.

Ahead of Chavez’s sentencing, he noted that he immediately began working with investigators, per Us Weekly.

The publication reported that prosecutors also filed court documents arguing for a lighter sentence due to Chavez’s cooperation.

Plasencia, another former physician involved in selling ketamine to Perry, was sentenced by United States District Judge Sherilyn Peace Garnett on December 3.

He received 30 months in federal prison and was also fined $5,600. Plasencia previously pleaded guilty to four counts of distribution of ketamine and surrendered his California medical license in September 2025.
