About Mark Siedlecki

Mark Siedlecki has been a leader in the technology industry for more than 37 years. He has the business, technology and management experience necessary to be Hamilton County’s next property assessor.

With Hamilton County in the midst of a critical growth period, Mark’s knowledge and experience are essential to ensuring Hamilton County properties are assessed fairly, through an equitable and efficient process, both transparent and accessible to all of our county’s property taxpayers.

Mark was raised in the Chattanooga area by his mother and father. His father escaped a Stalin-era Poland and found his way to Fort Benning where he met his future wife who worked as the Assistant to the Field Director of the Red Cross. After Mark’s Dad’s military service, the family settled in the Chattanooga area. His dad became an entrepreneur and, as a young teenager, Mark proudly worked with him in the installation department, learning first hand from his parents the importance of hard work and responsibility.

After graduating high school, Mark enrolled in Auburn University in Montgomery and joined the TKE fraternity where he served as the Chapter’s historian. While attending Auburn, Mark worked on Governor Ronald Reagan’s Presidential Campaign Advance Team. He also followed in his father’s footsteps as an entrepreneur. 

Mark founded his first company, a security system firm, when he was 19 years old. Within one year, he had 29 employees and a broad client base that included the mayor of Montgomery, a museum, and Southern Poverty Law Center co-founder, Morris Dees. Mark returned to Chattanooga in 1983, and launched a business phone system company. The company grew to have satellite operations in Cleveland, TN, Dalton, GA, and Atlanta, GA, and in its time was one of the largest ventures of this kind in Tennessee.

Following Mark’s initial business endeavors, he entered into a number of digital business ventures that honed his expertise in making technology work for people instead of people working for technology.  This involved solving complex technological problems crucial to making work easier, more efficient, and more profitable.  Mark has continued his innovative digital work and currently owns an internet programming and marketing firm, founded in 1995.

Mark’s business has supported the technology needs of sophisticated clients including Marriott, Sheraton, Delta Air Lines, KLM, Lufthansa, SAS Airline, Citibank, Bank of America, AIG and more.  Mark’s experience in business and technology means he understands how to make technology work for people and the importance of delivering a quality product to clients.  Mark believes that government should provide the same level of customer service to taxpayers. 

As Assessor, Mark has vowed to chart a path to improve the accuracy and digital deliverables provided by the Assessor’s Office.  This will begin with a comprehensive strategic planning process and acquiring and implementing technologies that will produce better assessments and provide the public easy access to important information. Mark wants to create a government office that is both open and citizen-oriented.

Mark says: “an Assessor should always be an advocate for fairness in our system. As property values go up and down, it is important that taxpayers know that the priority of the assessor’s office is equity. The assessor doesn’t influence market values or set tax rates, but the role of ensuring the playing field is level is a crucial one. My primary focus will be to ensure that Hamilton County property owners pay only their fair share and are confident because they can see and understand their assessed value.”

Mark has served in the leadership of Grace Episcopal Church, overseeing the effort to renovate the churches facilities and has worked with many charitable organizations including United Way of Greater Chattanooga and Chattanooga CARES and he currently serves on the Board of Sculpture Fields at Montague Park.
