Colleagues describe him as "I have known Andrew Cardno since 2013.  We started out coaching Science Olympiad together.  I later joined VizExplorer, a data analytics company founded by Andrew, primarily to work with him.  I was VP of Research reporting to Andrew, who was the CTO. Andrew is extraordinarily creative.  Whether it is finding innovative solutions for competitive science, data analytics or any engineering problem, he will always find a brilliant solution. Andrew is a world renowned expert in data warehousing, analytics and visualization.  The intellectual property that he has generated, articles and books that he has written usually takes a few lifetimes.  His productivity is mind boggling.   Andrew has tremendous energy.  He can manage 10 complex projects in parallel and still deliver on all of them.  He will somehow find the time for all of them. Andrew is a master salesman.  At VizExplorer he was instrumental in getting a sale with Choctaw (and many other customers) for a potential $17 million simply by demonstrating engineering excellence paired with sales and marketing acumen. Andrew is a role model as a person.  He is kind, empathetic and always has a positive attitude no matter what.  His energy, enthusiasm and kindness is sure to rub off on everyone he comes in contact with. Andrew is a genuine and conscientious person." and "Andrew is a brilliant all rounded professional. He is very hands-on, very technical and an incredible leader. He is a visionary and an idea machine. He is to Data Visualization, what Roger Federer is to Tennis. I worked with him on a multi-million $ project. His style of leadership is: he is not a micro-manager. He brought the best in me. He is pretty direct with his feedback. So there is no guessing there. He is very trustworthy and doesn't play politics. He is also a very articulate Technical Marketing Leader. He is able to break down complex technical concepts to simple English for his audience. He dons different hats - such as Marketing Executive, Sales Executive and CTO. It was a pleasure to work for him on the VizExplorer hostViz Software Suite. I highly recommend him. "
