I owe a debt of gratitude to many who have mentored, guided, and taught me throughout the years. My father, Stuart, opened up the world of computer programming to me and also imparted a passion to help others. Thank you to all the individuals at Teknion Data Solutions-my colleagues with whom I have the privilege to collaborate on a daily basis, the management, and its owners, who have made an investment in our training and growth and created an exciting place to build a career. Thank you to the Tableau employees and members of the online community who have created an incredible place to learn, share, help others, and have fun. Most of all, thank you to my wonderful wife, Kara, who has supported and encouraged me all along the way.
