I first met Susan in 2016 when I needed someone to help me gather information for my child custody…read morecase. I was attempting to get custody of my granddaughter. Susan was very personable and put me at ease right away. I explained what I needed and Susan set right to work gathering the information. She talked with my lawyer to find out what he needed and set about gathering the information. I even needed a Process Server and she was able to provide one for me. In the end, I was awarded custody of my granddaughter. Fast forward to 2019. My son passed away unexpectedly and I called Susan. She guided me and helped me through all the paperwork that was needed to arrange for son's final resting place. Every time I mentioned I needed something, Susan said she could take care of it. She was the Private Investigator for my child custody case. She was the Chaplain that performed the Memorial Service for my son and she was the Notary Public for papers I needed notarized. Susan is very professional and knowledgeable. Through all of this, she kept checking on me to make sure I had followed up on the tasks I needed to take care. I would highly recommend Gulf Coast Investigative Services and Susan if you need a private investigator, notary or Chaplain. She really is The Praying PI.

These professional people were very diligent and have always found more than enough background information to assist with our cases. They were also very helpful to other family members and friends of mine. This review is based on my doing years of business with this company. I'm not quite sure why Yelp is using the old address for this business but they are now located in Sugarland, Tx. On Dulles Ave. near the Dulles High School.
