North Texas Clinical Trials Site Team: 

Site Manager & Senior Clinical Research Coordinator  Jessica Anderson, CCRP  Just over eight years ago Jessica Anderson fell into her Clinical Research career by accident - as most of us in this industry do. Getting her start in a less than glamorous "office" the size of a broom closet sorting spit swabs and filing regulatory documents. Since those days she has contributed to over one hundred pharmaceutical trials ranging from phase I-IV and is credentialed by SOCRA. Jessica currently acts as the site manager for North Texas Clinical Trials, she truly enjoys wearing multiple hats a day and thrives in the ever changing, fast paced environment. Jessica is a firm believer in failing forward, the idea that education never stops, lives by a philosophy that every act and action effect the world, and urges everyone to never live the same day twice. Think like a proton, stay positive.
