About Us

SMrs. Fitzgerald in the old General Storeisson Landscapes is family-run company with a relaxed and friendly approach to our business. We love what we do, and have built a loyal following among our customers- who appreciate the quality of our work, and our commitment to excellent service.

Our award-winning staff includes Landscape Architects, Landscape Designers, Certified Arborists, Certified Horticulturalists, and Master Gardeners. On the installation side, we have built a stable of talented craftsman and landscape specialists to help make your vision a reality.

Sisson Landscapes was founded by Denny Sisson, a Landscape Architect and Great Falls native with a strong commitment to the community. Denny’s design leadership and thoughtful management have allowed Sisson to grow into a full service design/build firm with an upscale clientele who appreciate our responsiveness and discerning approach.

Our production facility is located in Sterling, VA, and we operate a fleet of 15 trucks, as well as a range of heavy equipment to allow us to address any job- large or small. We also utilize industry leading scheduling systems to ensure that our landscape installations and maintenance calls are executed in an expedient fashion.

Our design office is located in what we affectionately call the ‘Red Store’. Located at the corner Walker Rd. and Colvin Run Rd, the Red Store is one of Great Falls’ early structures, and originally served the community as a general store run by the Fitzgerald Family (Mrs. Fitzgerald is pictured here in the photo).

We thank you for your interest in Sisson- and certainly hope you will call us if you need any assistance!
