The Legal Side of Running a Business Is Too Important to Leave to Chance

Most business owners don't know what they're missing until something goes wrong — a contract they signed without reading closely, a lease that locked them into terms they didn't understand, an employee situation that should have been handled in writing from day one. We work with Long Island business owners to get ahead of those moments, not just respond to them.


We practice exclusively in business law. No personal injury. No family law. No general practice sidework. Every client we work with is a business owner, and every matter we handle falls within the lifecycle of a business — formation, contracts, leases, employment, transactions, and trademarks.


When you hire Barton & Bruechert Law PC, you work directly with your attorney. Not a paralegal. Not an associate. Every call, every review, every negotiation.

Business Law for Long Island

One Firm. One Focus.

Barton & Bruechert Law PC is a business-law-only firm — and that focus is deliberate. Business owners don’t need a generalist handling their matter between divorce filings and slip-and-fall cases. They need an attorney who understands the full legal arc of a business and can advise across all of it.



Our clients are small and mid-sized business owners across Nassau County, Suffolk County, and New York City. Some come to us for a single contract review. Most stay because one attorney who knows their business is worth more than calling around every time something comes up.

Common Questions from Long Island Business Owners

  • What types of businesses do you work with?

    We work with small and mid-sized business owners across a wide range of industries — retail, professional services, manufacturing, real estate, and more. If you own or operate a business and need legal counsel, we can help.

  • Do I have to come to your office, or can we meet remotely?

    Both options are available. Our office is located at 140A Broadway in Amityville, NY, which is convenient for clients throughout Suffolk County and Nassau County. We also work with clients remotely, including those based in New York City.

  • What's the difference between working with a solo attorney and a larger firm?

    At a larger firm, the attorney you meet in the initial consultation is often not the attorney who handles your matter day to day. At Barton & Bruechert, the attorney you speak with on the first call is the one who sees your matter through to the final document. There are no handoffs, no junior associates, and no billing surprises from staff you didn’t hire.

  • Do you handle ongoing legal needs, or only one-time matters?

    Both. Some clients hire Barton & Bruechert for a single contract review or business formation. Others retain the firm as their ongoing business counsel, the first call they make whenever a legal question comes up. We’re structured to support either relationship.

  • How do I get started?

    Call (631) 691-2600 or use the contact form to schedule a consultation. The attorney you speak with will review your situation and tell you plainly what can be done and what it will take.

Do I Need a Business Attorney to Review a Commercial Lease in Suffolk County?

Yes — and the reason matters. Commercial leases in New York are not standardized the way residential leases are. A landlord's form lease is drafted entirely in the landlord's favor, and the terms can bind your business for five, ten, or fifteen years. An attorney review before you sign is the only reliable way to identify provisions that could cost you significantly more than the review itself.


Barton & Bruechert Law handles commercial lease review and negotiation for tenants and landlords throughout Suffolk County. If you've received a lease and you're not sure what you're agreeing to, that's exactly the moment to call.
