A constellation of supply chain "stars" 

​

In recognition of a convergence of national postal services and private sector express companies in the global business of mail and parcel delivery, industry veterans, John Callan and Mike Comstock established Major Associates, LLC in 2001 as an independent strategy consultancy to advise clients on partnering opportunities with the U.S. Postal Service. They had come together earlier - Callan as a consultant for USPS and Comstock as a senior officer at DHL – to successfully conceive and orchestrate a breakthrough co-branded partnership between USPS and competitor DHL, launching USPS Global Express Guaranteed (GXG), as a new expanded international express-postal-parcel delivery service.

​

Callan had been consulting for the Postal Service on parcel product strategies as a “subject matter expert” under Coopers & Lybrand, beginning with the development of USPS’s online shipping application, Click-N-Ship, followed by the introduction of Parcel Select, its economical last-mile ground delivery service designed for consolidators.

​

Encouraged by their success with the USPS/DHL GXG venture, Callan and Comstock teamed up to form Ursa Major Associates and explore additional partnering opportunities for USPS,  successfully advising Pitney Bowes on the roll-up of its nationwide Presort Services business, followed by advising FedEx on the launch of its SmartPost last-mile delivery product via USPS Parcel Select.
