Mr. Lettington had more than 45 years of progressive experience in a variety of technical and managerial positions. For most of his career years he has been directly employed in technical and managerial positions in the computer and networking field. He has a broad base of knowledge and experience with all aspects of computer and networking technology from a hardware and software perspective. His technical experience has focused on networked (LAN and WAN) information systems. He has recently served in senior executive positions with companies organized to provide high capacity global internetworking products and services to deliver Internet access, as well as voice, video, and data services on an International Multiservice ATM backbone.


September 1998 – Retirement (gradual)

Mr Lettington was been most recently been engaged (for pay) in a private consultancy, joining forces with a small group of international business development professionals who share his vision of the market value of Global Multiservice Networks and his intense interest in all aspects the rapidly evolving technology associated with the information systems industry.


July 1997 - September 1998

With the acquisition of ATMnet by Verio, the vision of a global network ATM based network was no longer possible. Verio was totally focused on the deployment of a high quality IP only backbone for Internet services within the United States. Mr Lettington joined Telegroup, Inc. as Director, Asia Pacific Operations in order to hold the vision inaugurated at ATMnet. Telegroup initiated an ATM Project to plan and deploy a global multi-service network in order to ensure the company's future viability through expansion beyond the voice telephony market into the market for integrated services on ATM.


September 1995 - July 1997

In September, 1995 VisiCom Network Services became ATMnet. Mr. Lettington became Vice President and Chief Operating Officer of that new company. ATMnet grew into a National level Internet Service Provider focusing on high bandwidth internetworking solutions for corporate users. Under his guidance the network operations of ATMnet grew from a local focus in San Diego to a fully functional California ATM (Asynchronous Transfer Mode) fiber-optic backbone connected at 155Mbps to multiple ATMnet dedicated nodes and interconnected to other National Service Providers at multiple meet points including a connections at the MAE-West facility at NASA, Ames. Plans were developed for a complete twenty-one city US National backbone and construction has been initiated. Mr. Lettington also served ATMnet as Vice President for Marketing while recruiting efforts were underway to hire a senior marketing executive. Starting in January, 1997, Mr. Lettington became Vice President, International Operations and turned his focus to launching an Asia-Pacific Regional high capacity backbone and forming strategic alliances and joint ventures to serve that rapidly developing market. At the same time, he started to formulate specific plans for an European market entry and began long term planning for other International operations. As a founder, and senior member of the executive staff, Mr. Lettington is deeply involved in all aspects of ATMnet’s business and technical operations.


January 1994 - September 1995

Prior to being appointed Director, VisiCom Network Services, a new business unit formed as an entry into the Commercial Internet Access Provider market, Mr. Lettington served as Program Manager for VisiBridgeTM products. VisiBridge is technology which enables transition from outdated military computer systems to transition from closed systems to open systems. VisiBridge provides a migration path whereby commercial-off-the-shelf hardware can replace existing military hardware with full binary code capture of legacy code. VisiBridge employs the latest RISC processors and other VME based single board computer products to provide replacement hardware at a fraction of the cost, size, and weight of the systems they replace.

In addition to maintaining existing systems, his department supported a new initiative, NRaD Data Administration Program (NDAP), which will modernize the software technology employed and consolidate all corporate data into a single database operating on a UNIX based system employing fourth generation language and a modern relational database management system (INGRES). He participated in functional and data modeling of existing systems using IDEF0 and IDEF 1A. He personally prepared a report of available PC based automated tools to support IDEF0. During this period, the massive conversion project to convert all UNIVAC 1100 system COBOL programs and data to VAX/VMS Version 5.4 was initiated.
