What Clients Say about Jeff:

"Jeff has represented us in several corporate and litigation matters since we started our investment firm over six years ago.  It is rare to find a counselor who has the acumen to handle both business transactions and complex commercial litigation. Jeff has a natural ability to take control of and find a resolution in the most challenging and complex situations.  He has been a critical asset and a true partner in our growth and success."

Brandon W. Freeman
Freeman Group

"Pugnacious when needed but always professional, Jeff has proven to be an invaluable partner.  He is not only a skilled American lawyer—with knowledge of both the American and Japanese legal landscapes and cultures—he is an internationally minded asset to any multi-national organization."

Satoru Ando, President & CEO
Sumisho Computer Systems (USA), Inc.

"Jeff is talented, tough, open and honest. He is also practical, which is a characteristic you do not see everyday in an attorney. I am glad he is on our side."

Alvin Proctor, SPHR
Vice President of Human Resources
Kaneka North America LLC
Kaneka Americas Holding, Inc.

"Jeff handled a case of first impression involving a complex corporate merger. His tenacious, thorough preparation resulted in a total victory on the eve of trial—the opposition dismissed all of their claims with prejudice.  It was a display of superb preparedness."

William B. Owens
Crowell and Owens, L.L.C.
