About
prosurant.com
A licensed independent insurance agency. Real agent, multiple markets, personal service.
Who we are
prosurant.com is a service of Cary Greg McMahon Insurance, an independent insurance agency operated by Cary McMahon. We are headquartered in Crockett, Texas and work with clients wherever they need coverage.
We focus on flood, homeowners, and business property coverage — lines where carrier selection, local market knowledge, and getting the details right make a real difference to what you pay and what you get when you file a claim.
Why independent matters
A captive agent works for one company. They can only offer you what that one company sells, at that company's price. An independent agent works for you.
Because we're not tied to any single carrier, we can shop your coverage across multiple markets and bring you options. That means better pricing, better terms, and coverage that actually fits your property — not a one-size policy pushed because it's the only product on the shelf.
We don't get paid to push a particular carrier. We get paid when you have coverage that makes sense for your situation.
What we cover
Flood Insurance
NFIP and private flood policies for residential and commercial properties. We understand flood zone designations, elevation certificates, and what drives your premium.
Home Insurance
Homeowners coverage including windstorm and coastal exposures. We know where TWIA applies and how to layer coverage correctly for your property.
Business Property Insurance
Commercial property and liability coverage for small businesses. We work through multiple commercial markets to find terms that fit your operation.
Where we work
Cary McMahon is licensed in 42 states. Our primary market is Texas — particularly the Gulf Coast and greater Houston area — but we regularly work with clients in other states who need flood, homeowners, or commercial coverage.
If you're not sure whether we can help in your state, call us. If we can write it, we will. If we can't, we'll say so.
