When Leighton Campbell was the Lead Technology Consultant at Staples in Santa Monica he saved my business. He can diagnose computer problems faster than anyone I have ever seen. I have been running a business software program that is no longer supported, that seems only to run only a computer with a motherboard with a specific chipset. When that motherboard went down I thought I was finished, since it were no longer made and it seemed there were none available on the planet. Leighton to rescue. He left Staples and now has his own business. Whether its computers, mobile phones, networks, Leighton’s intuitive brilliance on all these has saved me more than once. And he is reasonable too! He works in the Santa Monica-West Los Angeles area. His e-mail is , phone is 818−850−2378 and his website
