  • 2007 Senior Employee Whistleblower Case v. Major Wire House

    Dear Stuart:

    I wanted to take a moment look back and personally express my appreciation for all of your efforts in how my was handled and concluded. Needless to say there were numerous venues which you had to choose from, the allegations involved whistle blowing, age discrimination, defamation, securities law violations and as you expected from the firest the multi-billion dollar corporation involved denied all claims and responsibility until the final bell. Your patience and professionalism will never be forgotten by me or my family espeicailly near the end when your counsel was invaluable in letting us make all crucial decisions without pressure but with a clear understanding of what could be won or lost depending on the course we pursued.

    Thank you again,
    Madison, New Jersey

  • 2007 Employee Stock Option Case vs. Morgan Stanley

    In seriousness, it may take me some time to get used to the reality of 
    winding up with this chunk of change — but seeing the check for yourself  sure
    helps bringing that home.  Maybe I will even make better use of  it this time
    around! Please give me a ring any time you’re in town, and I’ll do the same when I 
    visit the Big Apple
