Centrinex is rapidly growing in the call center management industry that focuses on Human Resources as our, our clients’ and our clients’ customers’ greatest asset. We know for a fact that it’s all about our people.

That’s why we recruit, train and retain the best call center talent in the industry.


Meet the People Leading by Example and with Purpose

Bart N. Miller



You would think a CEO whose company is considered a technology leader in their industry wouldn’t still rely on a 1980’s era record player to listen to music in his office. Bart Miller not only still rocks with vinyl but has the expansive record collection that would impress any audiophile.


Bart Miller appreciates the past but never stops looking toward the future.


So, when Bart saw a gap in the market for call center services serving banks, financial services, and other industries, such as healthcare, transportation and government, he didn’t pause for a moment and launched Centrinex in 2005. Never looking back, Centrinex has grown to over 500 employees and is recognized as one of the fastest growing companies in the nation.

More Facts

Bart believed that preserving the best of past call center practices and combining them with new technologies and new ways of doing business would propel Centrinex forward – as an innovator and thought leader. Bart was right.


Today Centrinex is at the cutting edge of the call center industry, not just in technology but also in data capture, analysis, conversion improvement, processes, and people management. To keep Centrinex in its leading role Bart gets intimately involved all aspects of the business. Ultimately, clients trust that Bart and Centrinex will help them improve their bottom line by increasing conversion rates, lowering acquisition costs and ultimately help improve their portfolios.


An east coast transplant, Bart was a finalist for the Ernst & Young Entrepreneur of the Year award. Bart also serves on the Board of Directors for the Online Lenders Alliance, is on the Executive Committee, and is their Treasurer.


Today, this married father of four spends his free time coaching his kids’ sports teams and plays on his own baseball team. With a strong sense of family and giving to others in need, Bart and his family are closely woven into the fabric of their community.


In his idle time… idle time? Do you really think Bart has idle time?

Jim Christiansen

President & CFO


As President and Chief Financial Officer of Centrinex, Jim Christiansen certainly has his hands full. He oversees the company’s operations, working in all aspects from human resources and training to quality assurance and information technology. His responsibilities include hiring, firing, benefits, training new employees, conducting QA audits for correct processes and procedures on a monthly basis, coaching, strategic planning and more. And, that’s just in his presidential role.

More Facts

Under the CFO umbrella, he is responsible for all the finance, accounting, payroll and receivables for the company. Plus, he takes care of the forecasting and cash flow to ensure there’s money to expand and to keep Centrinex aligned with its projections.


Christiansen worked in accounting and finance for the telecom business for most of his career, including 25 years with telecom giant Sprint Nextel. He learned a lot in the large corporate space, moving around to different groups, experiencing different corporate cultures, and dealing with growth, decline, spinoffs and ever-changing technology. It’s this vast experience that prepared him for these dual roles at Centrinex.


This Huskers fan got his degree in accounting from the University of Nebraska-Lincoln and obtained his CPA.

Rudolf J. Waldner



As a start-up, brick-and-mortar business kind of guy, it only made sense for Rudy Waldner to join Centrinex as COO. He coordinates the sales floor, develops the talent, drives the numbers, and basically does anything it takes to make a business hum.


Because Centrinex is in a constant growth phase, Waldner gets to deal with something new every day. Whether it’s starting up a new customer, product or enhancement, there’s always a new experience for him to thrive on.

More Facts

Originally from the east coast, Waldner’s educational background includes a bachelor’s in advertising from The City University of New York’s Baruch College and a master’s in management from Long Island University’s C.W. Post College.


Previously, Waldner consulted with Blockbuster in Germany, started a marketing department and served as Regional Director of Operations for Advance America, and served as VP of Operations for CLA – where he ran a product in 28 states for six years and opened up a collections call center.


Somehow, he found time to write his book, Marketing from the Trenches. The whole premise of the book is how to start a company, market it, and get it moving from the ground up. And it’s exactly what got him to Kansas City. Bart Miller read the book and invited him to run the business.


When Waldner isn’t developing training, improving performance and working on incentives for Centrinex, he can be found teaching his marketing program at UMKC, JCCC and K-State, out playing soccer, or traveling the world.
