Kathy WarnickKathy Warnick, Owner

As the owner of Warnick Consultants, Kathy Warnick has been helping businesses grow and prosper.

For over 25 years, Kathy has differentiated her services by refusing to believe that one size fits all needs. Her in-depth methodology for helping companies define their back office operations examines the entire company, not just the financial data. Her practical financial management systems have helped her small and medium enterprise clients grow their revenues and profits.

Kathy has developed a hand-picked team of financial professionals that use a unique process built solidly around the premise that the customer’s perspective is the key to success and that a customized financial management tool will, in turn, give the customer the information they need to achieve the desired results.

A certified Timeslips consultant for over 15 years, Kathy is one of a very few professionals in the State of Ohio with expertise to implement and train in this powerful tool. She is also a QuickBooks ProAdvisor with a keen attention to detail. Her personal high standards for maintaining integrity, pursuing knowledge through information, and achieving solid and consistent results have become the hallmarks of the Warnick Consultants’ that has earned her team industry-wide respect for their work.
