Hello debbiewebbie and thank you for your question.

The name of the attorney in question is actually 'Steven Cohen'

See:

"In a separate complaint that Illinois has not joined, the NICU nurses
accused the hospital of creating infection-control problems by
regularly exceeding its state-mandated NICU census, said Steven Cohen,
a Chicago attorney who represents the nurses"
