Large publicly traded company: Mark has been a tireless advocate for my company. He is widely regarded as the preeminent Kentucky tax advocate practicing today. I am very pleased with the results Mark has provided over the past 3 years and have enjoyed working with him.

Mark has made the ongoing tax work a great experience. We are not located in Kentucky and needed someone who could navigate the intricacies and nuances of the KY Dept of Revenue. An organization that was not familiar to our company or tax department. Mark is incredibly knowledgeable on our specific tax issue and has been critical in moving the issue through the various levels of KY tax administration. All the while being flexible, communicative and demonstrating strategic thinking about not only the case but helping us think thru the various alternatives and options. A true partner. I've recommended him to other companies and would gladly hire him again.
