In connection with our purchase of our church building, GRBM Inc. acted as our insurance brokers and advisers and we could not have been more happy with their service. Gary and Rob McCarthy handled our account and provided us with excellent advise in deciding on the level of coverage, as well as the insurer. We had a number of follow-up issues to address after closing and Rob was there with us every step of the moment. We highly recommend GRBM Inc. to any non-profit organization, or any other organization or individual for that matter.
