Meet The Faculty

The faculty members of the Division of Gastroenterology and Hepatology at Mayo Clinic in Scottsdale and Phoenix, Arizona, are committed to teaching and facilitating the growth of medical knowledge as well as performing high-quality clinical care. While our faculty members have published and lectured extensively, they remain clinicians first and foremost, so you will have direct access to their clinical expertise on a daily basis throughout your training.

During gastroenterology training, fellows have access to the following resources and support services:

  • Computerized patient records system allowing immediate access to medical records from any workstation in the clinic or hospital setting, and through broadband Internet access from home
  • Electronic access to medical journals and UpToDate
  • Endoscopy simulator
  • Teaching tapes for endoscopic training
  • Gastroenterology, hepatology, and nutrition texts
  • Pathology teaching files
  • Secretarial services for patient care and academic activities
  • Broadband access to the Internet through a dedicated T1 line to allow rapid literature search, slide creation, database management, word-processing, and e-mail
  • Professional graphic services for slide, video, and poster presentations
  • Dedicated office space

From the program director

Greetings and welcome to our online home!

At Mayo Clinic in Scottsdale and Phoenix, Arizona, our Gastroenterology Fellowship Program has a dual mission: to provide world-class training and excellence in clinical care and endoscopy and to create the next generation of leaders and clinical investigators.

Many of our GI and liver faculty are world-renowned in their subspecialties and our fellows' knowledge and skills are honed as they learn directly from the experts at the bedside, through didactic sessions, in the endoscopy suites, and by conducting clinical research. Our faculty are well represented among the ranks of leadership at national GI and Hepatology societies, leading to myriad opportunities for mentorship and sponsorship for our fellows, a critical aspect in the journey to establish academic careers. 

The exceptional number of resources available at our institution greatly facilitates your education during these fundamental years of training. Our three-year fellowship accepts three fellows per year and is expanding to four fellows per year in 2023, reflecting our program's growth. In addition, we offer advanced 4th-year fellowships in therapeutic advanced endoscopy with additional fellows in luminal interventions, transplant hepatology, and esophageal disorders. There are many exciting educational offerings including our Annual Update in Gastroenterology and Hepatology with interactive live endoscopy, Annual Mayo Clinic Esophageal Diseases Course, and our annual three-site Mayo Clinic Gastroenterology and Hepatology Course. 

Mayo Clinic is recognized globally for its collaborative and multidisciplinary approach to patient care. This is one of my favorite attributes of our institution, where I trained myself and chose to return as faculty and educator. I strongly believe teamwork is the path to clinical and academic success, and this spirit of camaraderie is how we best support each other on a daily basis and over the arch of our careers. In the words of Dr. William Mayo, "No one is big enough to be independent of others." If you are interested in an academic program, recognized nationally for its excellence in patient care, education, and research, and one that highly values teamwork, we encourage you to apply!

Visiting professors

Many prominent professors visit Mayo Clinic each year. They present their work during morning and late afternoon lectures. Residents and fellows are encouraged to take advantage of these opportunities to interact with experts from other academic centers and are relieved from clinical assignments to do so.
