What Sponsors & CROs Say About CTT

From a Sponsor

“You and your site have been one of the best I have EVER worked with.”

From a Sponsor

“We were both very impressed with the broad range of research services CTT can provide sponsors.”

From a CRO

“You certainly stand out from thousands of other sites for so many reasons including simply having an engaged PI who knows his patients and I can pick up the phone and have an actual dialogue with, to having dedicated coordinators who strive to do a great job, to your internal processes such as diligent prescreening to minimize SFs, as well as proven attention to detail, and ceaseless commitment to quality and success.  You guys are always honest, fair, quality-driven, and truly vested partners, which is appreciated more than words can adequately portray. You can only imagine how easy a site like yours makes my job.”
