A Safer Place to Build
We strive to provide our customers with the highest quality of legal protection.
Most firms meet their lawyer when something’s already gone wrong. Harbor & Main was built to change that moment. This firm exists to give growing businesses a safe harbor, a place where legal decisions are made early, calmly, and with intention. Before risk compounds. Before momentum stalls. Before legal debt starts eating into revenue.
We don’t just protect what you’ve built.
We help you build with confidence.
Our Philosophy
Legal shouldn’t feel like an emergency room visit.
As your Fractional General Counsel, I operate inside your business, not outside of it. I learn how you sell, how you hire, and how you scale. Then I help you make decisions with fewer surprises and more leverage. This is proactive risk management, not reactive cleanup. You don’t get memos you didn’t ask for. You get answers you can use so that you can focus on your revenue.
Harbor & Main is built for leaders who are actively building and growing their businesses.
We support businesses across the Chicagoland area and throughout Illinois from our Naperville office, which include:
- Professional services businesses
- Creative agencies and marketing firms
Venture-backed and growth-stage companies
These are organizations where contracts move quickly, intellectual property is central to value, and leadership benefits from legal guidance that is clear, timely, and aligned with business goals.
“We love what we do & create partnerships with our clients to ensure their business is positioned for long-term success.”
- Brandon Tillman
