Being able to assist anyone whether it's an attorney or pro-se with equal perseverance and in knowing we have done all that can possibly be done. I pride myself in providing a complete honest service to each client.

After many years being a process server and learning all that I could from that spectrum, I knew that I could provide a greater service to my own clients. I felt that the knowledge I possessed who benefit in completing services accordingly.

Tri County Investigations is an established and highly respected business in this industry for over 35 years. Our reputation is built on service, integrity and reliability.
