Jim Lipsit

Jim Lipsit

President, Co-founder and Owner

Always interested in electronics, Jim built his first telephone at age 13 and his first computer long before the Internet. In the early 80s, he led a mobile phone repair team, moving on to test and evaluate phones and accessories for McCaw Cellular AT&T Wireless where he won the 'Circle of Excellence' national award five times. Jim has developed numerous technical training classes, software programs, and processes for testing and evaluating phones. He has developed and written all the software test applications being used at the NAC; and he currently holds eleven patents in the wireless industry. Jim enjoys mountain biking and dune buggies, and he lives in South Florida with his wife Cindy, two daughters, and their dog Winston — in a fully-automated home where anything electric in the house can be controlled by voice commands via microphones or telephone.

Joe Murphy

Joe Murphy

Vice President of Business Development

With 17 years experience in the wireless industry, Joe's become a well-balanced individual who quickly understands 'big picture' concepts along with the minuscule details required to execute on those concepts. At the NAC, he is responsible for developing new business opportunities and supporting our new customers through the testing process. He's worked as an engineering professional at very large companies (AT&T, Lucent, and Broadcom) as well as smaller startup companies (Mobicom, Firefly Mobile). Joe says the best advice he ever received was from a CEO who told him, 'Don't come to me with problems; come to me with solutions.' Though he admits finding it infuriating at the time, today Joe appreciates the simplicity of the statement. He believes that how one deals with the normal obstacles encountered in the workplace separates the average employee from the exceptional one. When not working, Joe enjoys going to the beach, running, and sharing time with his wife and son.
