Our Story

How three friends turned a search for a contractor they could trust into a GC-Tech company built to do construction differently.

We build more than homes — see why we give back

The Journey to QB

Like many, Jonathan found himself unfulfilled in the rat race to retirement on the corporate hamster wheel. He knew there had to be “more” to life than his 7-to-5 W-2 job — and he found that “more” by building a business with two of his best friends.

During his travels around the country working for one of the top general contractors, Jonathan met Tom on an $850M highway, bridge, and tunnel project in Louisville, KY. They immediately formed a best-friend, brother-like bond through their analytical thinking and shared insecurities.

The Quality Builders team

While in Louisville, Jonathan bought his first property — simply because he was stingy and didn’t want to pay rent to someone else anymore. He purchased it through an online auction and used the “live-in-flip” and “house-hacking” strategies. That first property sparked a passion for real estate and pushed him to re-align his career.

To get re-aligned, Jonathan left his high-paying W-2 job to take a third of his salary at a property-technology (prop-tech) startup. It was there he met Bolanle and built an instant best-friend, sister-like connection through their intense work ethic and shared faith.

Having started his own real estate journey, Jonathan recognized the hardest part of investing was finding a quality general contractor he could trust. Leveraging Tom and Bolanle’s backgrounds in general contracting and technology, the vision of Quality Builders — a GC-Tech company — was born.

OUR MISSION

QB is in 100% alignment with our mission of building passion-filled lives for our team members, clients, and subcontractors — one project and one community at a time.

Why We Give Back

Giving back isn’t a marketing line for us — it’s where we come from.

For us, giving back started close to home. After a trip to Kenya changed the way he saw the world, Jonathan’s father founded Into Kenya, a 501(c)(3) nonprofit serving communities there. Watching that work up close shaped how we wanted to build our own company.

It’s personal in another way, too — co-founder Bolanle is from Nigeria. So serving communities across Africa isn’t a cause we picked. It’s part of who the QB family already is.

In Our Community

Our team volunteers in homeless shelters, serves at local food pantries, and helps rehab struggling Chicago neighborhoods.

Clean Water Abroad

We support efforts to build wells and bring clean drinking water to communities in Kenya, Nigeria, and the Philippines.

Time to Serve

Every QB team member receives two weeks of paid time off to serve overseas and be part of the work firsthand.
