Our Story
In 1987, Jamie Monaghan was a single working father of a four-year-old boy, struggling to make ends meet. Though he didn’t have much experience in the business world, he decided to start his own company. What he had was a hard-working, tenacious, and fighting spirit.
Jamie applied for his Landscape Contractor’s Board (LCB) license and, shortly after that, began beautifying yards. Learning on the job and fighting his way through obstacles, Jamie grew his company slowly at first but steadily. Nothing could stop Jamie from pushing through to success.
Jamie first met Colette when they were six in first grade and finally married in January of 2016. Together they’ve built a business that’s a fixture in the community.
