The Delaware psychiatrist who testified in the Lindsay Clancy case has resigned from Nemours, the health system said
Avram Mack testified on Friday, Aug. 21, and Monday, Aug. 24, as a prosecution rebuttal witness in the nationally watched case against Clancy.

A psychiatrist with Nemours Children’s Health in Delaware resigned his position after he began testifying in the nationally watched murder trial of Lindsay Clancy in Massachusetts, the health system said in a statement Friday.
Avram Mack testified on Friday, Aug. 21, and Monday, Aug. 24, as a prosecution rebuttal witness in the case against Clancy, 36, whose lawyers have argued was experiencing postpartum depression when she killed her three young children in 2023.
“Dr. Avram Mack is no longer employed by Nemours Children’s Health, he resigned on Monday, August 24th,” Shelley Meadowcroft, a Nemours spokesperson, said in an email.
Meadowcroft declined to comment further on “confidential personnel matters.”
Mack could not be reached for comment Friday.
CT Insider, which is covering the trial, reported that Mack’s resumé submitted during the trial listed him as a psychiatrist at Nemours Children’s Health since 2023.
Mack testified that he interviewed Clancy before the trial and did not notice any episodes that he would diagnose as bipolar, the Connecticut-based news site reported.
Mack also testified that Clancy having some odd thoughts, including fear that someone would take her children, was normal, CT Insider reported.
Kevin Reddington, Clancy’s defense attorney, reportedly sparred with Mack over the doctor’s experience working with adults, the definition of “postpartum,” and technical questions related to postpartum depression and psychosis.
