    • Testimonials

    • “I want you to know that one of the reasons we put up the fight we did was due to your dogged efforts. You never gave up. You never got discouraged. If a roadblock appeared, you found a way around it. You took a great load off my mind by not having to think of everything. We're a pretty good team together and I'm grateful for that. I can't tell you how much I appreciate your thoughtful analysis of issues dealing with the investigation and how it all ties together. You clearly are a great PI!! I look forward to many more years slugging it out in the trenches with you.”
