Dr Glenn Littenberg opened a solo GI practice in Pasadena in 1978 and within a year invited Dr Steven Petit to join him. We expanded to a group of 4 when joined in 1999 by Dr Casey Fu (and who also has a PhD degree in Nutrition from UCLA) and in 2004 by Dr Waleed Shindy (who also has a Masters of Public Health degree from UCLA). In 2002 we launched the doctor-owned and -managed Pasadena Endoscopy Center together with the physicians of Alliance Digestive Disease Consultants Medical Group (www.addcmg.com). In 2009 we are proud that together we screened nearly 8,000 patients for colon cancer at our Center!

Gastroenterologists are specialists in digestive diseases; we've gotten our knowledge and experience through college, 4 years of medical school, 3 or more years of Internal Medicine residency, 2 years of GI fellowship and then in practice.
