      It was a pleasure having you be able to assist in bringing about a successful conclusion given the dynamics you faced in the other room.   Your professionalism and dedication was most appreciated.  I will certainly keep you at the top of my list for future mediations.  Thanks again.  Take care.

 Both parties had pending Summary Judgment Motions and appeared content with taking the case to trial.  Mr. Kirwin quickly recognized that the real impediment to settlement was not a legal issue, but rather emotional, and was instrumental in getting the parties to quickly put aside their hostility towards one another reach a settlement.  Even as I write this, I am amazed of what he accomplished in three short hours of mediation.  I highly recommend Mr. Kirwin.
                     ~ A. Scott Brown, Esq.

       Mr. Kirwin provided mediation services for my client in a property line dispute.  Mr. Kirwin was knowledgeable, and objective.  Most importantly, he literally went the extra mile when our initial session did not resolve the case.  Mr. Kirwin continued his mediation efforts at the property, and spent a good deal of additional time trying to resolve our case.  I have recommended him to other attorneys, and would not hesitate to use him as a mediator in the future.
                     ~ Greg Jones, Esq.

       I felt that you did a superb job and your tenacity was most effective.  I appreciated you efforts very much.  I would not hesitate to utilize you services and to recommend you as a mediator in the future.
                     ~ Lindsay Nielson, Esq.

      You did a great job Mark.  I will suggest you the next time I've got a local mediation.  Please send me your CV, fees, etc.
                      ~ David N. Tedesco, Esq.

      Mark Kirwin did a professional job in settling cases in the Rancho Cucamonga Court.  He was successful in settling cases as an IVAMS mediator. He devoted his own time, or whatever it took to settle a case.  One in particular, he worked overtime–on his own time–to settle a case worth millions of dollars. He has a great disposition and demeanor for being a mediator.

      Mark was able to cut through the emotions to enable the parties to come to a sensible business decision.
                       ~ Michael A. Velthoen, Esq.

      Your mediation skills are excellent! Although I arrived prepared to go to jury trial because of no offers from defense, you resolved our dispute.
