Why stop by our table

A conversation at our table is a chance for us to actually get to know you, not just your resume. Tell us what you're studying, what kind of work excites you, where you picture yourself in five years. We're listening, and we remember. That connection is what turns into a real interview and, for a lot of students, a real career.

Last summer, twenty-eight interns joined O-A-K across our Michigan and Florida offices, working out of Grand Rapids, Kalamazoo, Traverse City, Naples, and Fort Myers. They didn't sit on the sidelines. Each was welcomed onto an active project and put to work from day one, alongside on-the-job training, weekly lunch and learns with company leaders, and a built-in community of fellow interns from across the states we serve.

The pathway is real

An internship at O-A-K isn't a summer detour, it's often the start of a career. Over the past decade, at least fourteen former interns have grown into full-time roles with the company. Brian Filipek interned in 2015 and is now a Project Manager. "The company's reputation initially attracted me to the internship, but it was the people and culture that convinced me to stay," Filipek said.

"O-A-K's internship program is designed to give students meaningful, real-world experience that simply can't be replicated in a classroom," said Jim Hopper, Florida Division President. Our interns become real members of project teams, working through problems and building relationships with clients and trade partners along the way.

What sets O-A-K apart

People-First Culture: At O-A-K, people are the driving force behind everything we build. We choose to do what's right, bring a can-do attitude to every job, and show up for each other, not just the project. Here, you're valued as a person, not reduced to a title or a task list.

Full Responsibility: When you join O-A-K, you become part of a company that's 100% employee-owned, so your success is directly tied to ours. You'll have the mentorship, training, and resources to do your best work, plus a real stake in the results. It's been our formula for growing careers, and the company, for more than 130 years.

Safety is Personal: At O-A-K, safety isn't a policy, it's a promise we make to every person on the jobsite and every community we build for. Our procedures are grounded in real field experience, not just paperwork, because protecting people always comes before schedules or deadlines.

If you're ready to build something that lasts, come find us on the road. We'd love to meet you. Have questions before then? Reach Camila directly at camilag@oakmi.com.

Celebrating our Intern Class of 2026

This summer, 28 interns joined O-A-K across our Michigan and Florida offices in Grand Rapids, Kalamazoo, Traverse City, Naples, and Fort Myers. Each intern was was assigned to active projects and put to work.

‍

The pathway is real

Over the past decade, at least 14 former interns have moved into full-time roles with O-A-K.

Brian Filipek interned in 2015 and is now a Project Manager. "The company's reputation initially attracted me to the internship, but it was the people and culture that convinced me to stay," Filipek said. Marco Garcia interned in 2020 and returned in 2024 as a Project Superintendent. Carlos Rapalo interned in 2024 and became an Assistant Project Manager in 2025. Sammuel Presmy worked the Cape Coral Technical College expansion as an intern and joined full-time in May 2026 as an Assistant Project Manager.

Employee-owned since 1891, O-A-K gives interns room to grow and people willing to invest in that growth. Many stay on part-time while finishing their degrees, then join full-time after graduation.

‍

Fridays Together: Learning Every Department

Every Friday, interns from all offices came together in-person and virtually to learn the functions that run O-A-K: Preconstruction, Marketing, Safety, Project Management, Accounting, and Superintendent work. Construction does not happen only in the field. These sessions showed our interns the full machine behind a project: Preconstruction planning the work, project managers driving it forward, superintendents leading the field, safety protecting everyone on the jobsite, accounting keeping it honest, and marketing telling the story.

Ian Miller, a Florida Gulf Coast University student, is proof our interns value their time at O-A-K. Ian first interned with us in 2025 on the FGCU Cohen Student Union renovation, following the project from active construction through closeout. He returned this summer for a new project and a wider view of the business.

"O-A-K's internship program is designed to give students meaningful, real-world experience that simply can't be replicated in a classroom," said Jim Hopper, Florida Division President. "Our interns become valuable members of project teams, participate in problem-solving, interact with clients and trade partners, and gain a deeper understanding of what it takes to successfully deliver complex construction projects."
