We have been extremely pleased with Dr. Walling’s site’s performance as a “rescue” site for our phase I schizophrenia study. We will use you again for any new early phase opportunities we have.

This company is very professional and courteous. My goal in life is to help out as best as I can, to defeat and destroy these illnesses. By being a strong candidate I know I am only doing a small part, but with CNS behind me I know that maybe some day these mental Illnesses will be a thing of the past for our present generations and into the future!

I want to congratulate you [Dr. Nirav Patel] on successfully enrolling several patients to date. Your monitor has been giving rave reviews about your site, which is consistent with my past experiences. We’re very pleased with the efforts you and your study personnel have put forth. Without question, you’ve topped the list of quality data.
