As partner, Tina aimed to elevate the high standard of service the firm’s clients had come to expect. She worked to develop and implement a unique vision for a cooperative, team-oriented corporate community, and placed a stronger emphasis on education for both clients and employees alike.
With the retirement of partner Steve Tilley in 2009, Tina took over ownership and daily operations and renamed the firm Calibrate CPAs. With the new incarnation of the company, Tina aims to inject efficiency, creativity, and a higher standard of service into every aspect of the business. Calibrate’s objective and mission is to help its customers “fine tune their financials,” and the company’s broad menu of services gives clients the security and peace of mind that comes with having all of their financial and accounting needs met in a professional and personalized way.
Tina has made lifelong learning and relationship building a focal point of her practice. She has been past president of her BNI chapter and serves on the Director Team, and also participates as a board member for several of her clients. Tina has been a pioneer in the area of Deming Management philosophy, a never-ending pursuit of quality and excellence.
Earlier in her career, Tina began sharpening her skills in building personal relationships working in government service for the City of Madison, Wisconsin. There she learned the importance of procedure and accuracy in her daily activities. She received a bachelor’s degree and later a Master’s Degree in Accounting from Upper Iowa University. She is currently a licensed CPA in both Wisconsin and Florida.
Now a long-time resident of Jacksonville, Florida, Tina enjoys spending time traveling the world, relaxing on the beach, and being active in her faith. Most importantly, Tina thrives on spending time with family. She and her husband, Paul, have two cats, Marley and Maceo. Despite her strong business drive, Tina considers her family her greatest success and first priority, demonstrating her firm belief that the most important aspect of life is personal relationships.

Matt Kruse – Read Full Bio
Since 2001 Matt has worked in the financial services industry, a much different career from his start in custom home electronics. It was his time at Hoyt Stereo in Jacksonville Beach that exposed him to entrepreneurship and the value of building a company with a dedication to quality.
Matt began his focus on business ownership when he started a successful insurance agency with his father, Paul and brother, Nathan in 2001. The Kruse Agency quickly grew into one of the most successful captive agencies in the nation as measured by annual premiums collected. While learning the insurance business, Matt discovered the natural relationships that exist between real estate professionals and financial services providers. He worked to bring professionals together with an emphasis on teaching clients the inner-workings of the business.
Matt’s crowning achievement with the agency was the creation of an education team that delivered training to first time homebuyers in the Jacksonville area twice per month.
