The Team

James Alexander


James started mowing grass in 1998 and has turned that passion for landscape into what Alexander’s is today. As an embodiment of the American dream, James has always strived to live up to the hard working principles that Alexander’s was founded upon. He is now a serial entrepreneur who has found success in various investment avenues and business ventures. Bringing this esteemed pedigree to Alexander’s, excellence is always the expectation.

As well as owner, James is heavily involved in the day to day operations and works closely with customers and crews. In an effort to be a respected leader, he takes care of his team day in and day out. You may see him on a property in one of the bright orange safety t-shirts, side by side with our crews! James has a passion for classic cars and trucks, and enjoys riding his Harley. He also lives in Florida for a reason, and can’t get enough of the outdoors.
