Why Choose Me

I started in the legal industry in 1990 working as a courier and process server in San Diego County. I worked for an Attorney Service for four years then started my first Attorney Service company in 1994. That company was Active Legal Service. I have also worked as an independent contractor for several other Private Investigation companies through the years. I have worked cases involving high profile individuals and celebrities. I continued to run Active Legal Service until I sold it in 2007 to pursue a career in Law Enforcement.

I returned to the Legal Service world in October 2010. I started my present company Medrano & Associates in October 2010 and in 2012 I became licensed in the State of California as a Private Investigator. I continue to hold a Process Server Registration in San Diego as well as my Private Investigator license. I have served over 35,000 papers in the past 33 years. I have been conducting Private Investigation work for the past 20 plus years with my expertise in surveillance. 

My biggest joy is helping children, so I really love to work child custody and child visitation surveillance cases. Many cases are different in terms of what hours I work, some cases start as early as 4:00 am and some continue through the night. 

I am a Native San Diegan. I am a father to four wonderful children so children are and their safety are extremely important to me.

Why should you care if an Investigator is local or not? First, if your Investigator is not local, he or she will most likely subcontract your case to a San Diego Investigator which can add costs and time delays. Secondly, an Investigator in San Diego will know the geographical area they are working in, the local laws, and the local agencies so I can get more done, quicker.

I use top of line hidden cameras, GPS devices, long range cameras and covert vehicles. I will not be caught surveilling people. I am also a seasoned Investigator that has testified in Court hearings numerous times and have never had my testimony stricken from a Court case. My promise to you is that by trusting me to handle your case, you will be satisfied. You are already in enough stress, let me take it from here.
