Our Mission is to maximize restoration of wounded warriors using advanced techniques in reconstruction and research in composite tissue regeneration.


The RESTOR Program has a history of success in discovering and developing novel techniques and therapies that could change the paradigm of wounded warrior care.


Donate now to provide patient assistance, opportunities for scientific collaboration and to help make San Antonio a Center of Excellence in Wounded Warrior Care.


Holistic restoration of complex devastating battlefield injuries with rapidly advancing and proven technologies and therapies that renew, regenerate, repair, reconstruct, and recreate human form and function.


The Restorative Endeavor for Service members Through Optimization of Reconstruction (RESTOR™) Research Program at the 59th MDW ST was initially conceived in 2011 and formally established in 2013. RESTOR™is a pioneering attempt at changing this traditional role of DOD research to serve DOD investigators and beneficiaries. RESTOR™ identifies critical capability gaps and addresses mission-critical research needs by facilitating robust, convergent research and partnership between military subject matter experts/investigators and civilian clinician-scientists and academia.

Such convergence of military and civilian programs is leveraged by RESTOR’s commitment to the development and delivery of novel therapies and strategies for far-forward medical care to minimize morbidity, improve survival, enhance performance and maximize recovery after disabling or life-threatening combat trauma. options have been exhausted.

Since its inception, RESTOR™ has expanded into a paradigm – shifting program that enables seamless transition of innovation to clinical implementation of conventional and cutting-edge reconstructive, regenerative, restorative, rehabilitative techniques, therapies, technologies and tools to serve our wounded warriors.


Establish a formal mechanism through which the breadth of combat casualty care and wound healing possibilities can be exploited at the most advanced research level and optimize clinical outcomes after injury or disability for soldiers and civilians.

Identify and facilitate a network of successful partnerships and collaborations between clinician scientists, academia, institutions, industry and DOD entities to improve and exploit the most viable technologies, therapies and techniques while adhering to standardized operating principles, regulatory, reporting and policy guidelines.

Implement a rigorous process to expedite transition of innovative therapies from extramural academia and industry to the veteran and military medical community.

Generate a viable pipeline of military scientists, clinicians and young intellect in the fields of regenerative, restorative, reconstructive, human performance, integrative clinical medicine, and allied specialties by providing an ideal, multidisciplinary training environment that encourages and sustains a coordinated research training experience.
