Arthur Graham, President & Chief Executive Officer


Arthur has over fifteen years of experience in IT, working mostly as a Unix systems engineer in a consultant capacity. He experienced the “dot-com boom” and Y2K, and was involved in various projects that became the foundations of many of today’s everyday conveniences. The new millennium heralded a new chapter in his career: working in the telecom industry. Cell phones were revolutionizing the way in which the world communicated, and Arthur was thrilled to be in the thick of it. Eventually, his career took another turn when he became Vice President of Strategic Development at Precise Publications, a medical communications company started by his wife, Dr. Kathleen Ohleth. In his current role, he has to study trends, learn at rapid rates, and display considerable flexibility. Precise Publications is no stranger to helping people, as one of their core operations is working hand-in-hand with the pharmaceutical industry. Creating Pedal for the Puzzle, a 501(c)(3) charity to raise money and awareness for autism, was a natural progression. As Chief Executive Officer and a principal founder, Arthur is driven to help make a difference.
