Andy Cronin Owner, Designer, Project Manager As an avid golfer for over 30 years with a single digit handicap, Andy Cronin knows golf. He's a former IT consultant gone green! After moving to El Dorado Hills and designing his own practice green, Andy recognized an opportunity to combine his business experience with his passion for and knowledge of the game of golf. He founded Sierra Synthetic Putting Greens & Grass in 2003 with the intent of providing superior customer service and professional practice greens and turfs. His extensive portfolio of projects includes practice greens for PGA Pro Kevin Sutherland and Empire Ranch Golf Pro Brett Taylor. Andy and his customers understand that it takes more than landscaping knowledge to build a superior green.
