Sierra Clinical Services

Since 2011, Sierra Clinical has been a full service ophthalmology CRO built by clinicians for innovators. With 500+ years of combined ophthalmic clinical research experience, our team does not just manage studies; we own them. Every project is guided by ophthalmic experts who practiced in the clinic, bringing real-world insight to every decision. We design and deliver end-to-end clinical trials. Whether you need high-level study oversight or deep data science expertise, Sierra has you covered. Our culture is defined by shared ownership, radical transparency, and expert precision. Our team ensures study sites and sponsors are not just inspection-ready but are also protected. This is why ophthalmic drug and device manufacturers trust Sierra to bring their vision to market.
