Our Core Values


We seek opportunities to face challenges and solve problems and take responsibility for the outcome.

Service First

We serve others before ourselves and go above and beyond to better the lives of our customers and colleagues.

Improve and Grow

We strive to improve our knowledge and abilities, never becoming complacent, and accepting and giving honest feedback to further collective development.

Team Play

We treat customers, colleagues, and vendors with honesty, courtesy, and respect, never assuming their needs are the same as ours. We all win when our team wins.

Creativity and Risk Taking

We are willing to step up and share ideas for improvement because we believe that innovation is a key to success with our products, processes, and services.

“On behalf of the Troy/Maryville/St. Jacob/Marine Chamber of Commerce, we just wanted to say how pleased we are with your continuing service for our Chamber. The customer service stands out with real live people, staff who arrive with a smile, e-mails that are responded to immediately, and extremely knowledgeable staff. Your phone system has been part of our Chamber family for over 15 years, and we continue to love all of the great features the system has to offer.”

–Dawn Mushill, Executive Director, Troy/Maryville/St. Jacob/Marine Chamber of Commerce – Troy, IL

“We went live today on the phone system, and things went very well. Your team did an excellent job on the project overall. Good action plans, and the dates were met, and the go live hit to the minute today. Your team is very good technically and with our team from a customer relationship standpoint. This is one of the best managed projects I have seen by a supplier in 30 years of management. Please thank the entire team on my behalf.”

–Frank Kretchman, V.P., Empire Comfort Systems, Inc. – Belleville, IL

“For anyone out there that is addressing an all-in IT provider, from anything from system and network management to voice and unified communications management, I couldn’t recommend CTS more highly. Their ability to integrate those systems together and be an all-in partner is invaluable.”

–Michael Wagner – Partner, Clayborne & Wagner Law Firm LLC

“CTS is there for you, that’s what it is – they are there. I can call or email them and they are always on top of support. A business can sell all the cool products they want, but if they can’t help their clients on the backend with support and training, the product is useless.”

–Jason Eigenrauch – Owner, Ike Honda
