Mark has done several projects at my house and I'd highly recommend him for any outdoor job. In a world full of contractors willing to take advantage of the unsuspecting, Mark is an honest and straightforward businessesman with the highest ethics. I would especially recommend him for garden and patio work. This guy knows plants. I'd often ask for a certain types of plants that are hard to find. Rather than sell me something expensive that would die quickly, he would suggest alternatives that would look just as great and survive the seasons. His knowledge of horticulture is on par with or greater than a university educated master botanist, and he has the integrity to give you a fair price and offer viable alternative to keep costs affordable.
