National Clinician Endorsements for Advancing Equity in Limb Preservation

National Endorsement

This initiative has received formal endorsements
from a broad range of nationally recognized clinicians, academic leaders,
health system executives, and community physicians.

National Professional Leadership Endorsement

Ross E. Taubman, DPM, FACFAS — Past President, American Podiatric Medical Association (APMA)

“Recent policy signals from CMS reflect a broader global recognition that downstream wound treatment alone is insufficient. Sustainable improvement requires early risk identification, preventive care pathways, and patient education that empower individuals before irreversible complications occur.”

National academic clinical leaders

1. David G. Armstrong, DPM, MD, PhD — USC / ALPS

“The Han–Giurini Model represents an important step toward a more equitable, sustainable future for limb preservation. Their outcomes surpass national benchmarks and offer a scalable strategy for reducing diabetic amputations.”

2. Elliot Chaikof, MD, PhD — Professor of Surgery, Harvard Medical School

“I strongly endorse this initiative. As disparities worsen among underserved populations, the Han–Giurini Model offers a critical, equity-focused strategy for reversing rising amputation trends.”

3. Aristidis Veves, MD, DSc — Harvard Medical School / BIDMC / Joslin

“This initiative holds tremendous promise for improving care in vulnerable populations and for establishing prevention as a cornerstone of public health policy. Its impact extends to patients and healthcare systems alike.”

4. Robert Gabbay, MD, PhD — Associate Professor Harvard Medical School

“Engaging FQHC where this is disproportionate risk, is a highly effective approach and one that I support”

5. Barry Rosenblum, DPM – Assistant Professor of Surgery Harvard Medical School

“Dr Han’s data clearly demonstrates this is achievable. I firmly believe that these are two of the most qualified members of our profession to ensure it succeeds.

6. George Pisimisis, MD, FACS, FSVS — Associate Clinical Professor of Surgery Loma Linda University School of Medicine

“Addressing these disparities in Southern California communities like Santa Ana and throughout Orange County is both urgent and achievable. With focused prevention, we can dramatically reduce suffering and improve outcomes for those most at risk”

Health Economics & Policy Leadership

7.  Charles Wang, PhD — Professor, Harvard Business School Health economics of diabetes complications and value-based care

Academic & Training Leaders

8. Jonathan Labovitz, DPM — Dean, Western University of Health Science

“The Han–Giurini Model directly addresses one of Medi-Cal’s largest preventable cost burdens. Their evidence-based, culturally tailored approach can reduce ulcers, prevent amputations, and save millions for California.”

American Diabetes Association

9. Robert Gabbay MD, PhD —Associate Professor Harvard Medical School. Former Chief Scientific and Medical Officer, American Diabetes Association
10. Mary JeanChristian, RD, CDCES American Diabetes Association-ERP Quality Program Coordinator

“It is encouraging to see how a bit of patient education in addition to medical care can make such a difference in health outcomes for our patients with diabetes. I am happy to endorse and support the work of my colleague Dr. Paul Han”

11. Nuha El Sayed, MD, MM.Sc Senior Vice President, HealthCare Improvement Science and HealthCare American Diabetes Association

Health System & Community Care Leadership
