Who We Are

A Diversity Organization With A Unique Perspective
About Total
REPRESENTING THE CHANGING FACE OF CLINICAL TRIALS
At TOTAL Diversity Clinical Trial Management, we think boldly about inclusion, and we believe forward thinking related to diversity strengthens us all; therefore, we strive to understand the realities of others in all aspects of our work.
As the first full-service Diversity Organization offering enterprise level as well as site specific support to the clinical trials industry, we have been at it for over a decade. With our experience as a Contract Research Organization and previously as innovators and Founders of one of the first centralized patient recruitment firms, a focus on diversity is in our make-up.
TOTAL has developed an operational, evidence-based delivery model to provide high quality, flexible, cost-effective patient engagement and diversity services to our Sponsor companies. As an example, our DTEACH© platform provides training to research sites on how to increase their capabilities allowing sites to meet diverse enrollment goals. The strength and success of our organization is directly related to the core team’s knowledge of the clinical trial process and how to identify, educate and engage the target population for participation in clinical trials.
In addition, our services include consulting, feasibility assessment for sites, training programs, patient recruitment and retention services and more. Our growing network of sites includes experienced diversity-oriented researchers as well as those who have access to underrepresented populations.
