"We want you to be happy."

Modern Dirtworks & Landscaping was established in 2014 by Joshua and Brekka Lengenfelder. As a locally owned business, we proudly serve the Bismarck–Mandan area and surrounding communities with high-quality landscaping services.

Joshua brings extensive experience in excavation and equipment operation, having been involved in the construction industry from a young age. Brekka developed a passion for landscaping and horticulture early on, working at a local greenhouse during high school and later earning a bachelor’s degree from North Dakota State University. She is now a certified Master Gardener through NDSU and also owns a plant care business, The Plant Geek.
