Tianna has thoroughly developed a strategy for creating a successful business relationship with us. She has been totally professional, and super amazing to work with. Her experience, and tenacity supercedes what expected of a PI. Unfortunately, we have encountered private investigators last year who were a great disappointment. However, if you give T&F Investigations of cal, I guarantee they will be your go to investigators for years to come. No disappointments here!
