John Costello

I’m John Costello, a notary and title insurance agent with Title Stream in Destrehan, Louisiana. I help clients navigate important signing and closing needs with a professional, detail-focused approach.

My experience includes real estate closings, title insurance matters, and general notary services. I understand how important accuracy, timing, and clear communication are when documents involve property, ownership, or other significant transactions.

I work to make each appointment straightforward and organized, whether I’m assisting with a real estate closing, supporting title-related documentation, or providing notary services for individuals and businesses. My goal is to offer dependable service while helping clients feel informed and prepared throughout the process.
