They’re Experts
In Their Field.
And Experts In
The Field.

We’ve built the number one project management and development company in the industry. And we’ve achieved this by building a team of Project Managers who are former architects, designers, contractors and trade consultants who know this business inside out. Our team brings decades of experience to each project, and offers more depth, professional knowledge and combined expertise than anyone else out there.

At PDSI’s Quarterly Meetings, we are reminded not to rest on past accomplishments. All of our team members embrace challenge in order to find innovative ways to create value, increase efficiency, and provide the highest level of service to our clients and partners. We seek new ways to use intelligence, flexibility, experience, and ability to overcome obstacles in pursuit of our clients’ success.
