Jay Worth started working in the Green Industry in college to earn money between semesters. He started mowing lawns for a landscaping company and then moved to a full-service landscaper. While attending University in Florida, he alsoworked on a palm tree farm and fell in love with the trees.  During the Great Recession in 2009, he was recruited to sell lawn care door-to-door. Having no other job options, he took the offer. This was the beginning of his full-time career in the Green Industry. After several years he took a break to work in media sales before returning to the Green Industry. Eventually, he landed at a full-service landscaping company doing Inside Sales for their lawn care and pest control programs. Jay gotpromoted to run all the marketing and grew his single Inside Sales position into an entire team of people. While working there, he spent every chance he got outside with the Tree Care team. He met them on job sites, talked to them at the shop, and even spent time in the field during ISA Arbor Day of Service events.  He eventually connected with SingleOps, a software he’d used while working at one of the landscaping companies. He found it to be the best option for Tree Care and full-service Landscaping companies. So, when they wanted someone to create resources for business owners, he found it was an easy product to get behind. Jay is passionate about best practices for healthy plants, sustainability, and being thoughtful stewards of the environment. He is also especially keen to help business owners and managers become more effective and efficient in their business practices. Jay sees no reason those two cannot coexist.
