Why Choose Us?

We are a leading clinical research center specializing in the design and conduct of clinical trials for new medications and treatments in various therapeutic areas including mental heath, neurology, and general health conditions.

CNS has four outpatient clinics located throughout California and a 25,000 square foot phase I clinical pharmacology unit centrally located in the greater Los Angeles area. Our staff members are experienced working with both healthy participants as well as select patient populations. Our CPU hosts a state-licensed, JACHO accredited, Psychiatric Health Facility (PHF). This hospital facility is uniquely capable of serving the needs for acute psychiatric clinical research as well as private hospitalization.

Our highly experienced staff is dedicated to providing quality service to our patients, partners and study sponsors. CNS was built on a customer service based foundation and we pride ourselves on our outstanding reputation as an industry leader.

CNS offers a supportive research infrastructure for investigators and primary care physicians. The doctors at CNS each have an average of 15 years experience in clinical research and have a wide range of specialties including neurology, psychiatry, geriatrics and internal medicine. Through this infrastructure, we are able to bring resources and tools to places where the patients are, to facilitate smooth study conduct and ensure GCP compliance. We help study sponsors prepare and submit regulatory documentation, monitor progress, collect data and most importantly, maintain the integrity of the study and protect patient safety.

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.
