Born and raised in the south suburbs of Chicago, Dr. Razzak completed his undergraduate education at the University of Illinois at Urbana-Champaign and medical school at the University of Illinois at Chicago.  He performed his Internal Medicine Residency at the Mayo Clinic in Rochester, MN and his Gastroenterology Fellowship at the University of Pittsburgh Medical Center in Pittsburgh, PA.  In addition, he completed an advanced endoscopy fellowship at the Virginia Mason Medical Center in Seattle, WA.

Other Interests: 

When he isn't working, Dr. Razzak enjoys spending time with his family and trying to keep pace with his two highly energetic kids who are constantly seeking adventure.  When time permits, he enjoys cooking, reading, learning to fish the PNW waters, and catching up on Chicago sports.
