Alex LaCroix grew up directly on the Upper Mystic Lake and has enjoyed kayaking, swimming, fishing, windsurfing and sailing there his entire life. As a graduate of The University of Vermont his sense of environmental stewardship extended beyond the simple beach cleanups he had done each spring and he became more active in the quest to cleanup and restore the Mystic Watershed. In 2001 he founded Mystic Property Maintenance, a local landscaping company with a unique focus on Integrated Pest Management and other green initiatives. Over the course of 10 years he found himself as spokesperson for the watershed and helped his customers bordering the Mystics and Spy Pond develop a clear understanding of how to properly balance having a great looking yard while protecting the sensitive water bodies abutting their properties. He became a certified pesticide applicator in 2004 and used that knowledge to help people avoid hundreds of unnecessary applications of pesticide. In 2011, Alex sold his business and is now a local residential real estate agent with Coldwell Banker in Arlington. He participated in the first annual Herring Monitoring Program in 2012 and participates in outreach events. His unique combination of having an extensive network in the community, an entrepreneurial background and direct interaction with the newest residents of the Arlington area, positions him well to help the efforts of MyRWA. Alex, his wife and son live in East Arlington and now enjoy Spy Pond for kayaking, running and photography.
