About Professional Grounds


Create valued relationships with our clients through extraordinary service and personal attention.

Professional Grounds operates on the foundation that excellent customer service and expert grounds maintenance should be the standard in the industry. We strive to go above and beyond to foster lifetime partnerships with the properties we maintain. Since 1974, we have been working with clients in Northern Virginia to create proactive grounds maintenance programs, increasing the value of their properties and lowering overall maintenance costs.

To this end, we hire the best in the business – our team of innovative designers, horticulturists, certified agronomists, landscape professionals, application techs, and administrative team are some of the most experienced and qualified professionals in the industry. Pro Grounds is built on landscaping expertise, innovative design, reliable professionalism, and personalized customer service.
