About Us

Greenskeeper Landscaping Grounds Maintenance

Our History:

Established in 1995, Greenskeeper Landscaping and Lawn Management, Inc. (Greenskeeper Landscaping) is a professional and complete grounds maintenance landscaping firm servicing the Washington, D.C. metropolitan area. Located in Brookeville, Maryland on a 32 acre working tree farm, with over 20,000 square feet of facilities that include offices and workshops. This self contained and centrally located facility assures clientele an efficient and immediate response to any grounds maintenance need.

Our People:

David Mamana, owner and president of Greenskeeper Landscaping, has over 25 years of experience in the landscape industry. Beginning his journey as a 12 year old, navigating his push mower throughout the neighborhood, he eventually built a loyal and constantly expanding residential base. With skill, perseverance, and sweat equity, this early venture continued to grow into a complete all encompassing grounds maintenance company, servicing both residential and commercial clientele. After earning a Bachelor of Science degree in Finance from George Mason University, David formally established Greenskeeper Landscaping and Lawn Management, Inc. 

Greenskeeper Landscaping's diverse staff of employees are thoroughly trained and kept abreast of new information and best practices in the constantly changing landscape industry. Our skilled and experienced staff has full communication with field personnel making every project a cohesive undertaking. Employees are competent, polite, service oriented, neat, reliable, and take personal pride in completed projects.

In addition to our staffing, we have a collaborative arrangement with other skilled professionals such as certified landscape designers and architects, irrigation designers and technicians, drainage experts, and outdoor lighting designers.

Professionalism and Customer Relations:

Greenskeeper Landscaping’s unparalleled work ethic enables us to work on multiple projects at once, yet always providing individualized attention and respect to our customers needs. Whether the project is a routine lawn visit or designing and building an outdoor living area from scratch, each client's needs are fully addressed.

We are committed to building long-term relationships with all of our clients by providing creative, reliable and quality service, focusing on the details and expectations of our customer’s landscaping needs. Our philosophy of Pride, Perfection, Performance, and Professionalism works because all of our business through the years has come from satisfied customers and referrals.


Greenskeeper Landscaping is licensed, insured and compliant with all state and federal regulations such as USDOT, OSHA requirements for employee safety, and maintains Workers Compensation Insurance. 

We are committed to providing a safe, healthy environment free from recognized hazards for all of our employees, customers, vendors, and visitors. As part of our commitment to safety excellence, we regularly attend safety awareness training seminars and construct hazard audits of our own operations. We firmly believe and practice that safety saves time, money, and lives.

Community and Environment:

Adopt A Road

Greenskeeper Landscaping strongly maintains that Community and Environment are an integral part of its business. We take pride in the knowledge that our ongoing efforts do make a positive difference.

The act of giving back to the community is also an essential component of our company policy. A few ways we accomplish this is through fundraising activities, plant donations, mulch drives, and participation in community beautification days.

We are continuously examining important environmental issues throughout all aspects of our business. Recycling is essential, as is the use of industry specific materials and chemicals that are proven both safe and eco-friendly to vegetation, animals, humans and the environment.

Another example of our commitment to the environment is our participation in Montgomery County’s Adopt-A-Road Program, which helps to minimize the accumulation of litter in the public right-of-way.
