His has written several books on this subject but is extremely knowledgable in all areas of forensic science.
He is an excellent trainer and a vast source of information. Donn is a valuable resource to the entire forensic community.

Donnell has successfully created a system for development of new or upcoming forensic laboratories, that allows his firm to monitor and assess the level of success for each developed component. I have worked with many training and development firms in the past and PBSI is among the best.

I worked with Donnell Christian for several years, attempting to develop the forensic laboratory capabilities of the government of Turkmenistan. He effectively managed & coordinated the travel, training and meetings to effectively accomplish our mission. In spite of difficulties he was able to move forward to execute plan of action. I met with him at the annual meetings of the American Academy of Forensic Science since he left the Departmrnt of Justice and would welcome an opportunity to work with him again.
