An Inside Look

at TMC

Our Story

In 1987, Cheryl O'Brien founded Technology Management Corporation as a premier independent technology and telecommunications consulting firm in Excelsior, Minnesota. TMC was developed on the strong need for someone who would look out for the best interest of the client, while keeping their integrity and not accepting commissions from any vendors or service providers. At that time, the industry was engulfed with big telco carriers and not enough independent consultants to protect the clients.

During the early days of TMC, our presence in Minnesota grew in the corporate world as the technology consulting company that can truly save you millions on your telecom services and technology budget. We worked with most of the big names in Minneapolis and began expanding into other states. 

In the early 2000s, TMC opened up services for IT/AV Low Voltage Design and become a full service technology consulting and low voltage design firm.

Since then, TMC has serviced clients in almost all 50 states, saved over $287 million for clients worldwide, worked with almost every major architecture and engineering firm and have become a certified small, women owned business in 10+ states. We have also dedicated ourselves to supporting our fellow woman-owned small businesses and helping mentor young women starting their businesses.


We are proud to create and design sophisticated and innovative IT systems for industries such as Airports, Sports, Healthcare, Government, Corporate America and Education. We recommend only the best IT solutions for our client's needs and help prepare organizations to smoothly expand and diversify into the future.

To this day, we are proud of our client centered approach to vendor-neutral consulting and have created long-term, entrusted relationships with our clients by ensuring their technology and business success.
