Ellen Sicher is the psychiatrist who treated Violet before her return to Los Angeles.
When Violet found herself in New York, she saw that Ellen Sicher was looking for someone to take over for her during her maternity leave. Violet came in for an interview that went well, but when asked why she was leaving her current practice, she couldn't stop looking at Ellen's belly.
This led to them talking about Violet's attack and Lucas's birth. Ellen forced her to talk about the difficult parts, including that she instructed Katie on how and where to cut. Ellen got her to realize that in doing that, she was putting Lucas ahead of herself, something she did again when she gave him to Pete.
She is a psychiatrist in a private office in New York.
