Our preconstruction services lay the foundation for safe and successful outcomes.

We specialize in assisting our clients in developing green solutions that minimize the impact on your budget.

"They'd work all day and then have to button-up so 80,000+ people could come and enjoy the game. Talk about people really committed to their work, to doing the job well and around our schedule."

“If you are interested in construction, go for it. There is an opportunity in this line of work and it is exciting! I see women on jobsites today more than ever!”

“I have been in construction for over 30 years - the last 14 years at JP Cullen - have proven to me that when you work for a company that understands the importance of employees and family, who treat you like one of their own, it makes it very easy to get up and go to work every morning. ”

“I genuinely believe that this project wouldn't have been as successful as it was without JP Cullen. The team's overall expertise, knowledge, and experience is huge. They went above and beyond on communication.”

Abby Abramovich
Project Team Leader

“Entering the trades as a woman can be scary and very challenging. Don't give up on the idea just because it doesn't seem like the normal thing to do. Everything that you gain along the way; friends, strength, confidence it's well worth it and all of your hardwork does pay off in the end. So don't be afraid to join the trades because you think you can't do it. Because you can!”

Amber Peterson

"I wanted to drop a note to let you know how much I appreciate your team and all the great work they’ve done for us at Baker Tilly! I will continue to trumpet to anyone that listens how truly phenomenal the JP Cullen team is to work with and how stellar the product you deliver is!"
