The Architecture and Construction Management business began as Culbertson Associates and later changed to Landmarkk. The work involved design, construction management, real estate, and conceptual estimating. The company has intentionally stayed small so that Steve, the owner, can focus on projects instead of management. Although single family projects are most of Landmarkk's work, the company also provides similar services for small commercial and multi-family projects. Clients include individuals, real estate professionals, contractors, other architects, and investors.
