PinPoint Testing Credentials and Certifications
I would certainly continue to endorse Dr. Endres as an expert in this field. I have always been grateful for his assistance in our case as I know we could not have put everything together and prosecuted our case with success without his testimony. I was fortunate to find someone with his background, and qualifications, who was willing to step outside his daily mold and accept such a task.
We have not had any K2 issues since the defendant was successfully removed from our community.”
