The company has established offices in key metropolitan areas across the U.S. - Baltimore, Phoenix, Philadelphia and Boston. Paul Houlihan, who has nearly 30 years computing sales experience, will lead sales and customer service initiatives in all Western markets. Houlihan will be based in Nallatech's Phoenix, AZ office. Previously, Houlihan was regional sales manager for SKY Computers and has held positions with Thales Computers, Lockheed Martin, LSI Logic and Texas Instruments.

He has served in sales for companies including Altera, Motorola Computer Group, Radstone and Pentek and has held design engineering and management positions at Martin Marietta and Avnet Electronics. Nallatech doubled total sales worldwide in 2003, and over 50 percent of revenues were generated in U.S. markets.
