I know a thing or two about telecom. I've negotiated contracts with about a dozen telecom companies over my career, and it's about as rewarding as a root canal. I worked with David at Comsource on my past contract negotiation and he was able to provide me with accurate and timely information, excellent pricing, and good follow up and follow through. He was always available when I needed him (even while on vacation) and as a result we have a lock on a good price for a reliable service. I would highly recommend his services to anyone looking for a through and OBJECTIVE review of their telecommunications services.
