Advancing Medicine Through Clinical Research
For over 25 years, Spring Clinical Research has been a trusted partner to patients, physicians, and leading pharmaceutical companies — conducting clinical trials that shape the future of healthcare.
Our Mission
At Spring Clinical Research, our mission is to improve patient lives by connecting Houston-area communities with access to cutting-edge clinical trials. We believe every patient deserves the opportunity to benefit from the latest advances in medicine — often before they are widely available.
We partner with world-leading pharmaceutical and biotech sponsors to conduct rigorous, ethical, and patient-centered research across a wide range of therapeutic areas including cardiology, gastroenterology, rheumatology, endocrinology, pulmonology, and more.
Our Story
Spring Clinical Research was founded in Houston, Texas with a simple but powerful vision: to make clinical research accessible to the diverse communities of the Greater Houston area. What began as a single research site has grown into one of the region's most respected clinical research organizations, with 12 locations spanning Houston, Sugar Land, Katy, Tomball, and beyond.
Over the past 25 years, we have enrolled thousands of participants in studies that have contributed to FDA-approved treatments now used by patients worldwide. Our commitment to scientific integrity, participant safety, and community trust has made us a preferred site for top-tier sponsors including Pfizer, Eli Lilly, AstraZeneca, Novartis, and many more.
