PETERSON INVESTIGATIONS REVIEWS

I used Peterson Investigations for last minute service of process of court documents on a party. Eric coordinated and insured the documents were served on-time and that I quickly received both a correctly completed proof of service and an invoice. If you need the job done in a short time window you want someone reliable and you get that with Peterson Investigations.

I am really happy with the outcome of my service request with the Peterson Investigation team. They took care of a personal issue in a matter of days that I was dealing with for months. I highly recommend the services of Peterson Investigations, true professionals.

Eric, provided fast courteous service. He was very responsive to text messages and phone calls. He located a person within a week who tried to escape without paying. I would highly recommend Eric and his staff.

Leisha is absolutely incredible at what she does! I’ve had the pleasure of working with her for several years, and she truly stands out as one of the best investigators and process servers in California. Her expertise and instincts in conducting investigations are unmatched. If others say someone can’t be found, Leisha is the one who proves them wrong! Leisha has a real talent for finding people that other process servers couldn’t track down. She’s a true master of her craft.

We are a firm that relies on integrity and professionalism, and Fenton Investigations is that. They provide the highest grade of workmanship and tenacity. We highly recommend their service to anyone seeking a reliable and honest professional. Thank you.
