After over 60 years of being a family-owned business, John Mullen & Co. was acquired by long-term client DB Insurance in April 2021. Recognizing the strength of the existing JMCO business model, DB Insurance agreed that JMCO should remain a fully independent TPA. We still run our multi-line adjusting firm in Honolulu, HI, according to the principles established by our founders, John and Margaret Mullen, many years ago. We believe that our staff builds and retains the good reputation of our company. In return, our employees' welfare and security is one of our primary business goals. We are sincerely proud of our staff.
Our Mission
John Mullen & Co. has adopted Kina’ole as our daily mission—the Hawaiian word for “doing the right thing, in the right way, at the right time, for the right reason, the first time.” Another word—Aloha—captures the company values, and John Mullen & Co.'s employees embrace the “aloha spirit” in all of their day-to-day activities with each other—and with our customers.
Call (808) 531-9733 for more details on our multi-line adjusting firm's services.
