Dr. Jian Wei Zhang, MD
Dr. Jian Wei Zhang is the founding physician and president of Main Street Medical (Metro True Care Medical, P.C.) — a practice he built from the ground up in 2007 to serve the Asian-American community and broader Chinatown neighborhood.
A board-certified internist, Dr. Zhang trained at Sun Yat-Sen University, Zhongshan School of Medicine — one of China's most respected medical institutions — before completing his residency at St. Barnabas Hospital in New York. His clinical acumen is matched by a deep commitment to the patients and community he has served for nearly two decades.
Dr. Zhang speaks fluent English, Mandarin, and Cantonese, making him an invaluable physician for patients who prefer to discuss their health in their native language. His approach is thorough, unhurried, and genuinely patient-centered — a rarity in busy Manhattan medicine.
In addition to leading the Manhattan clinic at 139 Centre Street, Dr. Zhang also sees patients at the Brooklyn and Queens Rendr locations, reflecting his extraordinary dedication to the communities Rendr serves.
