What Our Clients Say…

"I solicited information from various vendors that could perform a telecommunications audit for the City of Mesa. Elizabeth Supica, the Senior VP of TelCon Associates, responded to my solicitation, as well as four additional vendors. Immediately upon speaking with her, I knew that she was very thorough, and cared about the customer. The decision was made to have TelCon Associates perform the audit. The service received was top-notch, and we were very pleased with the results. Annual savings of approximately $400,000.00 were realized. I recommend them without hesitation and would utilize their services again, should the need arise."
Pamela Tyson, IT Procurement Coordinator, City of Mesa

"The greatest benefits derived from our telecom audit was not only the savings they found for us, but also the benefit of having TelCon handle the telecommunications support for all of our 250+ properties. They have proved to be everything they projected to us and more."
--Pam Brown, IT Vendor & Budget Manager, UDR

"Karen Thatcher is working with me now and I have been very impressed so far with her services. Her first draft of recommendations for us resulted in significant savings. She has been very prompt and communicative with all our work so far. I am impressed with her attention to detail as well as her knowledge of how companies such as Verizon present and sell their different plans. If you are interested in having a professional look at your phone system, TelCon Associates comes highly recommended."
