But that record does not reveal Mr. Greenberg's other run-ins with law enforcement and the judicial system, which are not required to be disclosed to Finra.
In 2000, Mr. Greenberg admitted in an arbitration proceeding that he had phoned someone who did a lot of business with a colleague and told him, inaccurately, that the colleague was known for shady business practices, according to a record of the proceeding. Mr. Greenberg was not punished for what the three-person arbitration panel deemed was defamation because the statute of limitations had expired, the panel said in its decision.
In December 2006, Mr. Greenberg was charged with harassment and criminal mischief, according to court papers and a police blotter item in The Lake Oswego Review. He had violated a restraining order taken out by his ex-girlfriend, the second woman to ask for protection against him, according to the court papers. Mr. Greenberg eventually pleaded no contest to a misdemeanor charge of criminal trespass and agreed to limitations on his movements, according to a plea deal reviewed by The Times.
And eight years later, Mr. Greenberg was charged with violating another restraining order taken out by a different ex-girlfriend. The woman, Anne Cost, had obtained the order against Mr. Greenberg after, she said, he threatened to burn down her house. Now, she told the police, Mr. Greenberg was menacing her again, trailing her in his car.
"You could have placed a pizza box between her back bumper and Mr. Greenberg's front bumper he was so close to her," a Lake Oswego police officer, John J. Brent, wrote in his report of the incident, which was reviewed by The Times. Ms. Cost declined to comment.
After that September 2014 arrest, Mr. Greenberg's mug shot appeared online in a report about the arrest. Morgan Stanley employees in Seattle and Portland shared it via text messages and emails, according to the seven former Morgan Stanley employees, most of whom said they did not want to be identified because they feared retribution by Mr. Greenberg or the bank.
"Everybody knew," said Jani Beatty, a former vice president at Morgan Stanley's private bank. She added, "I considered him my friend until I understood the full extent of his actions against his intimate partners."
When he learned of the arrest, Paul Amsbury, a Morgan Stanley branch manager and Mr. Greenberg's boss, passed information about it, including the mug shot, to Curtis Peterson, the firm's Pacific Coast regional director, in San Francisco, according to Ms. Beatty and two other former bank employees. Mr. Amsbury's message: Mr. Greenberg was not fit to represent Morgan Stanley and should be dismissed.
Mr. Amsbury declined to comment. Mr. Peterson did not respond to requests for comment.
After Mr. Amsbury flagged the arrest, a high-ranking compliance official from Morgan Stanley's New York offices flew to Portland to meet with Mr. Greenberg and Mr. Amsbury, the former employees said. (Ms. Beatty, who worked in a separate business line in Mr. Greenberg's office, said she did not recall the visit.)
Morgan Stanley officials soon were confronted with more issues involving Mr. Greenberg.
In June 2015, his second ex-wife, Traci Williams, wrote a series of Facebook posts that described her ex-husband's alleged physical and verbal abuse. The posts did not name Mr. Greenberg, but there was little doubt about whom she was referring to. Her friends commented on the posts and criticized Mr. Greenberg by name. And a lawyer for Mr. Greenberg complained about the posts to Ms. Williams's lawyer.
Among the commenters was Alex Burlingame, a Morgan Stanley manager in Seattle who had worked with Mr. Greenberg for years. He "liked" the post and added a personal message: "Hang in there, Traci! So sorry to see that one acts this way. Nancy and I r thinking of you!"
Mr. Burlingame did not respond to requests for comment.
That summer, Ms. Williams said she started receiving what she perceived to be threatening letters in the mail. "I CAN SEE YOU," read one message made up of letters cut out from magazines. She reported the harassment to the Portland police, who opened an investigation. Their main suspect was Mr. Greenberg, according to emails between Ms. Williams, her lawyer and a Portland police officer that were reviewed by The Times.
The police eventually turned the case over to federal prosecutors, according to a July 2015 email to Ms. Williams from the Portland police officer. The United States Postal Inspection Service was also part of the investigation.
One day in early 2016, federal authorities showed up at Mr. Greenberg's Morgan Stanley office to serve a subpoena related to the investigation, according to Edie Rogoway, Ms. Williams's lawyer. On March 1, Greg Nyhus, an assistant United States attorney, said in an email to Ms. Rogoway, reviewed by The Times, that his office was reviewing documents obtained from several subpoenas.
A spokesman for Mr. Nyhus's office declined to comment.
Ms. Williams, meanwhile, asked her lawyer to complain to Morgan Stanley that Mr. Greenberg was making it hard for her to access her children's Morgan Stanley wealth management accounts.
Ms. Rogoway said she spoke to a Morgan Stanley lawyer, Bernard Kornmehl, about the accounts. Mr. Kornmehl declined to comment.
She said she told him that Mr. Greenberg had a history of abusing women.
Later that day, Ms. Rogoway emailed Ms. Williams about the conversation. She reported that Mr. Kornmehl had said that "many sides" were aware of Mr. Greenberg's alleged history.
