Houston Regional Campus


The Houston Campus was established in 2014, with the first cohort of students arriving in June 2015, ready to embark upon their clerkship experiences at the #1 ranked hospital in Texas, as recognized by U.S. News and World Report. Since that time, the campus has grown by leaps and bounds with the continued development of the clerkships, as well as an array of fourth-year elective opportunities at Houston Methodist Hospital and many other institutions that make up the Texas Medical Center.

MD/PhD Program

At Houston Methodist, we believe that innovative education and dedication to teaching the science of translational medicine is essential for training future academic medical leaders. As part of a joint MD/PhD degree program, our institutions provide translational research opportunities at the Houston Methodist Research Institute and the Institute of Biosciences and Technology.


In addition, 2019 will usher in the nation’s first medical school track blending medicine and engineering into a four-year masters of engineering and MD degree through the EnMed program. This cutting edge program will create a new type of doctor, the ‘physicianeer’ to address our nation’s demand for more innovative approaches to care delivery and development.

Houston Aggie Medical Society

Together with the faculty and students of Texas A&M, and the support of the Aggie former student led Houston Aggie Medical Society (HAMS), we continue to strengthen the partnership between our two institutions as we to train the next generation of physician leaders in medicine and research.

Institute of Biosciences and Technology

The major Texas A&M College of Medicine research presence in Houston is the Institute of Biosciences and Technology, located in the heart of the Texas Medical Center. Houston Methodist is part of a larger system with six community hospitals serving the greater Houston area and an additional facility currently under construction. Houston Methodist prides itself on physicians and staff who exemplify the ICARE values of integrity, compassion, accountability, respect and excellence. Patient safety, quality and service are our highest priorities.

We offer numerous opportunities for education and research. We have recently joined a group of leading health institutions in Texas to co-found TMC3, a 30-acre collaborative research campus expected to be complete in 2022.


Our clerkship directors and coordinators assure that all of our medical students get the necessary curriculum required, utilizing an ever-expanding number of medical services and facilities in our community.
