Insurance Agency Serving Long Island and New York City
Carlstan Insurance Agency is a family-owned independent insurance agency based in Melville, New York. From our office on the Nassau/Suffolk border, we serve businesses and residents across Suffolk County, Nassau County, and every borough of New York City — the same markets we've worked in since 1948.
We're licensed in New York, New Jersey, and Connecticut. Whether you own a restaurant in Queens, a home in Huntington, a condo in Manhattan, or an apartment building in Brooklyn, you're in our service area. And when you call, you reach Adam or Ryan Erickson directly — not a call center.

Where We Serve
Our office is in Melville, NY — on the Nassau/Suffolk border along Route 110. From here, we serve businesses and residents throughout the region. We handle everything by phone and email, so you never need to visit our office.
Our office in Melville sits at the western edge of Suffolk County, making it our strongest local market. We serve businesses and homeowners throughout the county — from Huntington and Smithtown in the west to Islip and Babylon along the South Shore.
Communities we serve in Suffolk County include Huntington, Smithtown, Commack, Hauppauge, Melville, Babylon, Bay Shore, Islip, Brentwood, Bohemia, Farmingdale, South Huntington, Huntington Station, and surrounding areas.
Nassau County is our second primary market. We serve homeowners, small business owners, and commercial clients throughout the county — including coastal communities on the South Shore where specialty carrier access matters.
Communities we serve in Nassau County include Hempstead, Garden City, Hicksville, Mineola, New Hyde Park, Great Neck, Oceanside, Valley Stream, Lynbrook, Elmont, Floral Park, Bellerose, and surrounding areas.
Queens
Queens has the highest concentration of small businesses of any NYC borough — restaurants, auto service shops, retailers, apartment buildings, and professional offices are dense throughout. We serve commercial and personal lines clients across the borough, from Flushing and Astoria to Jamaica and Jackson Heights.
Brooklyn
Brooklyn is home to some of the fastest-growing restaurant and retail corridors in New York City, and one of the largest renter populations in the metro area. We serve Brooklyn restaurants, apartment building owners, retailers, and renters with coverage built around the specific risks of operating in a dense NYC borough.
Manhattan
We serve Manhattan restaurants, professional offices, and apartment building owners with the same industry-specific commercial programs and direct-agent access as our Long Island clients. For personal lines, we work with Manhattan renters and condo owners who want a human agent relationship rather than an app.
The Bronx
We serve Bronx restaurant owners, apartment building owners, and small retailers — with particular focus on workers' compensation, BOP, landlord liability, and EPLI for businesses operating under New York City's employment laws.
Staten Island
Staten Island has the highest homeownership rate of any NYC borough. We serve Staten Island homeowners, small business owners, and residents whose work or property crosses into New Jersey — where our NJ license is a direct advantage.
The Carlstan Insurance Agency offers commercial insurance and personal insurance to clients across Long Island and New York City. We provide coverage for clients seeking Suffolk County insurance, Nassau County insurance, Queens insurance, Brooklyn insurance, Manhattan insurance, Bronx insurance, and Staten Island insurance. As an independent agency based in Melville, NY, we have been helping businesses and families find the right coverage since 1948. Ready to get started?

Why Long Island and NYC Businesses and Residents Choose Carlstan
75 years in the New York market. We've been placing insurance across Long Island and the five boroughs since 1948 — three generations of the same family, in the same markets, with the same carrier relationships.
Small agency. Real access. You'll work with Adam or Ryan directly. No rotating service team. No re-explaining your situation when you call. The agent who quotes your policy is the one who picks up the phone.
Fast and flexible. We move quickly because we're small. Most quotes are turned around within one business day. Coverage changes, certificates, and questions are handled the same day in most cases.
Independent. We're not tied to any single carrier. We shop Travelers, Progressive, Andover, Kemper, and others at every renewal — giving you access to the right coverage at the right price, not just whatever one company offers.
Always reachable. Email is monitored 24/7. Voicemail is checked regularly. When something comes up outside business hours, we don't disappear.
