Lenken Construction Services is founded on the belief that we have a unique opportunity to impact others through the buildings we erect and renovate to all of those that we interact with along the way. By making personal connections, holding ourselves and others to a high standard of ethics and quality and by building an environment of shared goals and objectives we can be a positive influence to everyone that we encounter.



“Lenken” is a German word that means "to give movement direction." It is a word that captures the spirit of our efforts to serve our clients with a unique approach to discover the direction of a successful project.  We do this by building a relationship based on a commitment to mutual goals and values. We integrate design and construction services together creating an environment that maximizes the ability to explore options early on and understand each option’s impact on construction timelines, coordination issues, and cost. The owner can have as much or as little input in any phase of the project as appropriate, ensuring decisions remain on track with their priorities.


Lenken has the expertise and knowledge to help you with many services at any point in your project. Whether it is Design-Build, Construction Management or General Contracting, Lenken has the vision and ability to bring your project to its fullest potential.
