Outstanding Private Investigator!!! Got everything I needed and kept me informed at all times. Denise had to locate people for interviews. District Attorney was unable to locate the witnesses and Denise was able to located the witnesses. I was kept informed by either a phone call or via e-mail. Denise is very personable and gets the Job done. I look forward to a continuing business relationship with her. Everything turned out great. Denise's investigative information allowed me to get a better deal for my client. THANK YOU, Denise
