Arbitration Policy


I ask all of my patients to sign an arbitration agreement.    In my practice of medicine I, of course, aim to provide the highest quality of care to all of my patients and to prevent disputes from arising.  However, I believe that if disputes do arise, arbitration is the best method to address them for all involved parties.  Please see below for information on arbitration and a copy of the arbitration agreement you will be asked to sign. There is no need to print and sign the agreement as we will have it for you to sign in the office. Please let me know if you have any questions.


Thank you.
