At Wohlsen, we believe building projects are delivered most efficiently when a cohesive plan exists from start to finish.

That is why we have integrated our design-build construction methods throughout the initial planning processes. We have found that this eliminates many of the issues that can bring projects to a grinding halt.

Learn more about our design-build process, how it leads to a more quality result, gives us the flexibility we need when challenges arise, and how it leaves less room for risk.

You can take our word for it – we’ve been doing this a long time.

Lisa Murray, Director of Learning and Development, held a team building session for our Sussex Family Courthouse project team in Georgetown, DE.

One of the Superintendents, Andrew Cox, (pictured here) is helping to lead the team and is using the skills and strategies he is learning in the ten-month program, Leadership in the Field.

Leadership in the Field is designed to empower Superintendents to positively influence our external partners and subcontractors for high levels of collaboration and communication, especially during times of conflict.

We are lucky to have Andrew on our team!
