David Hertzog learned the craft in a classroom and perfected it on Sussex County lawns
Hertzog Lawn Mowing Service has been caring for Millsboro yards for more than 15 years. David started the company and still runs it, and that matters when you hand someone the look of your property. Lawn care here is about trust, curb appeal and the long relationships that come from showing up on the day you said you would.
The work covers full-service landscaping, seasonal cleanup and exterior property care, all shaped around your vision and your budget. Everything starts with a walk of the property and a free estimate. Browse the five jobs the crew takes on or ask David a question directly.
