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.

Hello everyone at CNS in Garden Grove! You all are amazing, friendly, caring, and of course exceptionally professional people. “YOU” made the uniquely sensitive nature of the clinical trial experience fun and well, not so sensitive.
