Thanks to everyone who made this book possible. As always, I owe a huge debt to my wife, Jenn, for putting up with my late nights, and to my children, Colton, Liam, Camille, and John, for being so patient with their tired dad who has always overextended himself. Finally, I would like to thank Shawn Trautman, my line dancing instructor. This will be the year that we complete the United Country Western Dance Council's goal of making line dancing a competitive sport worldwide.

I would like to thank God for the gifts and opportunities afforded me and most of all for sending his son Jesus Christ. I would like to thank my wife and children for their patience and support as I worked on this book. I would also like to thank Brian Knight for the opportunity to learn and grow in the field of Business Intelligence. Finally, I would like to thank Anthony Martin, Dustin Ryan, Bradley Schacht, Devin Knight, Jorge Segarra, and Bradley Ball, each one of these individuals have provided guidance and mentoring through the years and have had a profound impact on my career.

Manuel Quintana is a Training Content Manager at Pragmatic Works. Previously, he was a senior manager working in the hotel industry. He joined the Pragmatic Works team in 2014 with no knowledge in the Business Intelligence space, but now speaks at SQL Saturdays and SQL Server User Groups locally and virtually. He also teaches various BI technologies to many different Fortune 500 companies on behalf of Pragmatic Works. Since 2014, he has called Jacksonville home and before that Orlando, but he was born on the island of Puerto Rico and loves to go back and visit his family. When he isn't working on creating new content for Pragmatic Works, you can probably find him playing board games or watching competitive soccer matches.

Thank you to all my family and friends who support me in all of my endeavors. Special praise must be given to my wife for supporting me during late hours working and some weekends being dedicated to writing this book, without her I wouldn't be the person I am proud of being today. Also, I must say thank you to all my coworkers at Pragmatic Works; each one of them has mentored me in one way or another, and all my success can be traced back to them. I hope to make everyone mentioned here proud of what I have done and what I will achieve.

I'd like to thank Packt for giving me this opportunity, the content and technical editing teams, and particularly Divya Poojari, acquisition editor, and Amrita Noronha, senior content development editor. As Power BI continues to evolve, it is necessary to be flexible with the outline and page counts, and I greatly appreciated this autonomy.
