Flourish – San Antonio

About Us

Flourish Research is where clinical trials thrive.

Our History

Starting as Clinical Trials of Texas (CTT), Flourish San Antonio has served the community for more than 20 years and is one of the largest and most capable research sites in the United States. Founded in 2001 by Kay Scroggins, RN, Flourish San Antonio championed all EUA and FDA COVID vaccines in a multitude of studies during the COVID-19 pandemic and has today over 100 employees. Our Chief Medical Director, Douglas Denham, DO, CPI, along with 10+ other San Antonio-based board-certified physicians conduct studies in their respective medical specialties. Flourish San Antonio is currently led by Leisel Koerber, BBA, CCRC, Executive Vice President, who has been at CTT for more than a decade.

We serve our study participants and strive to make their clinical research experience wonderful; many of our participants have completed multiple studies as a result. Having served the San Antonio community for more than two decades, we are very proud of our relationships within the community and our work to help develop life-saving therapeutic solutions in areas that directly affect our community such as COVID-19 vaccines, Diabetes, Fatty Liver, RSV vaccines and many more.

Championing Inclusivity In Your Research Journey

At Flourish Research, we strive toward excellence. In clinical trials and healthcare, excellence means everyone deserves the best care, regardless of their race, color, gender identity, religion, ethnicity, physical abilities, age, sexual orientation, or veteran status. We embrace employees, customers, and patients from all underrepresented groups to help make this vision a reality.

Flourish Research is driven by a diverse and inclusive community of passionate people who are committed to improving the quality of life of communities around the world. Flourish is committed to a safe work environment where all employees, customers, and patients are included, and treated with dignity and respect.

Flourish strives to build an organization that attracts and leverages diversity in our staff, which reflects the diversity of our local communities. We promote education, acceptance, and inclusion because there is beauty in diversity. The more diversity we have in our team, the more unique perspectives, and ideas we share, and the better prepared we are to serve our communities. WE SEE YOU. WE ARE YOU. WE EMBRACE YOU. WE CELEBRATE YOU!
