Our History

       Southern NH Software, a division of D.L. Computing Corp. was founded in 1985 by Dan Lavalliere at the age of 15. What began as a business that specialized in custom software programming has transformed itself over the years based on the changing needs and demands of small businesses.  As the industry demanded the need for affordable hardware and software in the early 90's, Southern NH Software changed its structure to provide local consumers and businesses with deep discounts on hardware and software products along with the expertise (when needed) to implement these products into their businesses.   As time progressed and local office/electronics superstores emerged, while still providing a large amount of hardware and software products to our clients, our focus shifted heavily into IT Consulting by implementing and maintaining computer networks for them.
