Our Experience
Experience Matters! Tami began her career in science as a Staff Research Associate in a population genetics laboratory at the Scripps Institute of Oceanography (SIO). After four and half years at SIO, Tami transitioned from fish to humans and began her tenure at the San Diego Police Department Crime Laboratory. Tami spent 21 years as a DNA Criminalist in the San Diego Police Department Crime Laboratory, 8 years as a Field Evidence Technician (FET) Coordinator and Trainer, and 14 years as a Crime Scene Reconstructionist. Ron spent 29 years with the San Diego Police Department, including 15 years as a detective in the Homicide Unit, 3 years on the FBI Joint Terrorism Task Force and 2 years in the Street Gang Unit.
As a team, we bring years of case investigation and courtroom testimony to the table. Though we have been a part of some amazing cases, our motto continues to be that you can never say you have seen it all. We are currently developing our skills in advanced fire investigation and genetic genealogy and look forward to adding these disciplines to our services.
