Case Management Philosophy

Mr. Peña’s arbitration philosophy is very straightforward. Having tried cases before some of the best judges and arbitrators in Texas and the United States, Mr. Peña has learned how to manage cases fairly and efficiently.

As a labor and employment arbitrator, Mr. Peña fully understands the positions of the employer and the employee. He is well respected by employer/management attorneys and employee/union attorneys (references available upon request).

Mr. Peña manages his arbitration hearings in the same way his favorite judges and arbitrators conducted their hearings: he treats the parties, the witnesses, counsel and union representatives with dignity. He allows the parties the opportunity to make their cases and present their evidence.

Mr. Peña listens carefully, reviews all the evidence, applies the controlling law and delivers intellectually honest decisions.
