Callender Center for Clinical Research

The Callender Center for Clinical Research is a specialized clinical research site and contract research organization (CRO) based in Glenn Dale, Maryland. Founded in 2004 by Dr. Valerie D. Callender, a prominent dermatologist and professor at Howard University, the center is a recognized leader in dermatological research, particularly for conditions affecting patients with skin of color. The facility conducts Phase 2 through Phase 4 clinical trials across a wide range of indications, including alopecia areata, vitiligo, acne, and aesthetic treatments like dermal fillers and neuromodulators. By partnering with major pharmaceutical companies such as Pfizer, Revance, and Eli Lilly, the center plays a critical role in bringing innovative therapies to market while ensuring diverse representation in clinical data. Its expertise in hair loss and pigmentation disorders has made it a premier destination for both industry-sponsored trials and academic research.
