UNIONDALE, NY / ACCESS Newswire / June 10, 2025 / Marquis Who's Who honors Mitchell Parrish, co-founder and chief executive officer of H Clinical Inc., for his distinguished contributions to life sciences and global clinical trials. Mr. Parrish's career reflects a rare combination of legal expertise, regulatory innovation, and patient-centered thinking that has reshaped how trials are conducted, particularly across Latin America.

Championing Localized Innovation in Global Research
Under his leadership, H Clinical has emerged as a pioneering provider of home-based and community-integrated clinical trial services in Latin America. In addition to home trial capabilities, H Clinical provides patient recruitment, clinical research staffing, and procurement and storage of supplies and equipment, delivering comprehensive support to trial sponsors and research sites alike. What began as a vision to bridge the gap between global trial sponsors and local patient populations has become an operational reality in more than 700 communities across 22 countries. H Clinical's model is designed to improve trial access, reduce site burden, and strengthen data quality through local relationships, cultural fluency, and real-time support.
"H Clinical is built on the idea that global research only succeeds when it works locally," said Mr. Parrish. "Our teams live and work in the communities they serve, and that makes all the difference in patient engagement and outcomes."
From Legal Leadership to LATAM Innovator
Before founding H Clinical in 2021, Mr. Parrish held senior executive roles in law and clinical operations, including executive vice president and general counsel at Quorum Review IRB (now Advarra). He oversaw review boards responsible for more than 12,000 trials annually, helped spearhead the development of the industry's first cloud-based eConsent platform, and directed the merger of Quorum with Advarra to create a leading force in the commercial IRB space. His leadership experience and exposure to Latin American regulatory agencies gave him key insights into the region's strengths and barriers, shaping his vision to redefine research access.
A Thought Leader and Global Collaborator
In addition to his leadership at H Clinical, Mr. Parrish has advised public and private sector organizations globally and has been a guest speaker and published thought leader on decentralized trials, ethics, and regulatory innovation. He previously served as a steering committee member at the Multi-Regional Clinical Trials Center of Brigham and Women's Hospital and Harvard (MRCT), and was a board member for Life Science Washington, contributing to policy advancement and regional industry development.
Record-Breaking Trial Reach Across Latin America
Recently, H Clinical supported the largest home trial operation in Latin American history, spanning thousands of patients in underrepresented communities across Argentina, Brazil, Colombia, Mexico and Peru. Its decentralized clinical trial services have played a critical role in supporting drug and vaccine development, while empowering local populations with health education and increased treatment options.
Looking Ahead: Expanding Access, Advancing Innovation
Looking ahead, Mr. Parrish and H Clinical are focused on expanding clinical trial inclusion, improving regional infrastructure, and elevating Latin America's role in global research innovation.
