I was a sitting judge for over 24 years, have practiced law and have been a mediator and arbitrator since 2011. Many attorneys have tried cases in my courtrooms or mediated or arbitrated a case with me.

The disclosures listed above will not affect my neutrality in this dispute.

With Judge Ward's assistance, we were able to obtain an amicable resolution of the case.  Just as when he was sitting on the bench, Judge Ward showed understanding, temperance and intelligence in addressing the issues.  Settlement was fair and adequate the nature and extent of injury.  I would not hesitate to use ADR Systems’ assistance in the future.
