I cannot overemphasize the importance of meeting with clients as early as possible in the disability claim process. You rarely get a complete picture of a claim until you meet the client in person.
The more time you spend talking with the client, the better the claim is developed and presented to the judge.
Whenever possible, client hearing preparation should be face to face with the client. I find one thing often leads to another with these conversations, and you discover interesting details that tend to demonstrate disability.
