About Us Colorado Mediators & Arbitrators™ | COMA was founded in 2005 to resolve disputes while balancing quality, cost, and efficiency. We are committed to fairness and fair process in both Mediation (negotiated settlement) & Arbitration (a private judge renders a decision.) COMA mediates business, real estate, and divorce matters with excellence. Our arbitration program offers a cost-appropriate, targeted approach that removes prohibitive arbitration costs by tying the amount of claim to the type of hearing and that provides for expediency and efficiency.
