Michael Lallana, 31, entered not-guilty pleas to charges of depositing an offensive substance into a co-worker's water bottle at work.
Authorities linked the substance, semen, to Lallana after the victim brought the water bottle to a laboratory for testing.
The victim retained attorney Gloria Allred to speak on her behalf Tuesday.
"She suspected that something was very wrong with the water in her water bottle. And she had the good judgment to take this water in the bottle to a laboratory to be tested," said Allred at a Tuesday news conference outside the courtroom.
The victim believes she first drank water tainted by Lallana back in January. Then, three months later, it happened again, and that's when she went to a lab and then to police.
Allred says her client is emotionally traumatized and has taken a leave of absence.
The victim and Lallana worked for Northwestern Mutual Financial Network.
"We look forward to the day when women are treated with respect and dignity rather than being victimized and assaulted by those who appear to enjoy committing criminal assaults and sexual acts against them," said Allred.
Allred says she and her client are considering their legal options, and that the victim will testify against Lallana.
Meantime, the judge has issued a protective order while Lallana is out on bail.
Lallana's attorney declined to comment on the case.
It's now set for a pretrial hearing in October.
