We are a computer services company based in Unionville, MO. The owner of NEMSI has over 18 years experience in the computer industry. NEMSI was designed specifically to go against the grain of large, over-priced companies. Not only are you being overcharged for computer services, but customer service in almost every industry is lacking as well. We are going to change all that. Our mission is to serve the NEMSI area with the best customer service possible. By offering a free diagnostic, we are stating just that. Welcome to our website, and we hope you refer us to your friends and family.
