Pros

Costello Construction is a hard working company. They self perform over 30% of their work which means there is a lot of action. The comradery and team work is un matched with other companies. You truly feel like a team working together towards a greater goal. The majority of their buildings are complex and very architecturally pleasing drawings. No job is the same as the one before. Also, the benefits and salary are very generous as well. There is a ton of room to grow and be successful in the company. There truly feels like there is no ceiling.

Cons

Sometimes longer hours are needed depending on the phase of the project.

Pros

From my very first interaction with Costello Construction two years prior to starting my position, I was left with an incredibly positive impression. I was struck by how deeply the company values community, not just in the projects it takes on, but also in how it treats people. As a family-owned and operated business, there’s a real sense of pride in what they do, and it shows in every detail, from community centers and senior housing developments to their thoughtfully run hotel, where I had a wonderful experience of being involved through my previous position before even joining the team. On my first day, I was welcomed with a team lunch and provided with a clear list of tasks, logins, and expectations, which made the transition smooth and stress-free. Located on the Columbia Lakefront, the office is bright and inspiring, with water views and lots of natural light. The company also provides great health insurance and provides all the tools and programs needed to succeed. If you’re looking to be a part of a mission-driven team where people are kind and committed to meaningful work, Costello Construction is a company where you can truly feel proud of what you’re helping build.

Cons

Truly a positive experience! Nothing negative to note at this time.
