John V. Gahagan, MD, FACS, FASCRS
Clinical Associate Professor, Surgery - General Surgery
BioJohn V. Gahagan MD is a Clinical Associate Professor in Colon & Rectal Surgery. He leads the Colon & Rectal Surgery residency program as Program Director and serves as Chief of Surgery and the Medical Director of Supply Chain at the Stanford Tri-Valley Hospital. He joined Stanford in 2019 to build the Stanford Colon & Rectal Surgery practice in the East Bay at Stanford Tri-Valley in Pleasanton and at Stanford Health Care – Emeryville. He has training in advanced minimally invasive surgical techniques including robotic and laparoscopic surgery. He has authored several textbook chapters and original articles in peer-reviewed journals. His clinical practice is focused on the surgical treatment of colon and rectal cancers, inflammatory bowel disease (ulcerative colitis and Crohn’s disease), and benign colon and anorectal diseases (diverticulitis, hemorrhoids, fistulas, fissures). He believes in patient-centered care and multi-disciplinary approach to the treatment of diseases of the colon, rectum and anus.
Dr. Gahagan is passionate about surgical education. He serves as an Associate Program Director of the Stanford General Surgery Residency Training Program. In that role, he oversees resident evaluation and feedback. He led the revamp of the program’s evaluation process and Clinical Competency Committee – work that has been presented at the Association of Program Directors in Surgery (APDS) and the Accreditation Council for Graduate Medical Education (ACGME). In 2021, he established the Stanford General Surgery Endoscopy rotation, giving general surgery residents an opportunity to gain endoscopy experience by collaborating with faculty gastroenterologists and fulfilling their graduation requirements. In 2026, he established the Colon & Rectal Surgery residency program at Stanford and serves as the Program Director. At the time of accreditation, this program was the only ACGME accredited Colon & Rectal Surgery residency program in Northern California. In addition, he is the General Surgery Rotation Director for the Stanford Tri-Valley Family Medicine Residency. On a national level, he is an associate question writer for the American Board of Colon & Rectal Surgery and serves on the USMLE Step 3 Test Development committee and the USMLE Management Committee.
He also serves in various administrative roles, including as Chief of Surgery at the Stanford Tri-Valley Hospital. In 2025, he was appointment Medical Director of Supply Chain for the Stanford Tri-Valley Hospital. He is a member of the Stanford Medicine Partners Quality and Credentialing Committee, the Stanford Tri-Valley Operating Room Committee and the Stanford Tri-Valley Medical Executive Committee. -

Francisco Galdos
Affiliate, Department Funds
Fellow in Pediatrics - CardiologyBioFrancisco earned his undergraduate degree in Human Developmental and Regenerative Biology from Harvard University, graduating magna cum laude. He subsequently completed his MD/PhD at Stanford University School of Medicine. During his doctoral training under the mentorship of Dr. Sean Wu, Francisco published one of the first comprehensive maps of human cardiac cell development using pluripotent stem cell-based models. His research contributed to the development of machine learning tools and genetic tracing systems that identified and characterized human left ventricular cardiomyocytes in vitro, enabling the modeling of left ventricular development in hypoplastic left heart syndrome. Francisco has authored multiple first-author publications and has been awarded funding from both internal sources and the NIH (F30, T32). He has received numerous accolades for his work, including the prestigious Harold Weintraub Award, and has presented his research at various national conferences. As part of the accelerated research pathway at Stanford, Francisco is focused on the genetic and epigenetic mechanisms underlying heart failure and heart development in congenital heart disease, with the ultimate goal of developing novel therapeutics for pediatric patients.
