Practice History
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 (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 (PEC) together with the physicians of Alliance Digestive Disease Consultants Medical Group. In 2009 and 2010 we are proud that together we screened nearly 8,000 patients each year for colon cancer at our Center! We are nationally accredited and have been certified as a Center of Excellence by the American Society for GI Endoscopy. In 2012 our group is becoming a division of Southern California Gastroenterology Associates, with 33 gastroenterologists in 12 offices across the San Gabriel and San Fernando Valleys. Among many other things, this will enable us to develop a comprehensive electronic medical record and coordinate your care better with many other medical groups. 

Mission Statement

Our group strives to provide optimal care for your digestive health problems in an environment in which you can be comfortable and feel confident you are getting the best advice and the most effective treatments.

We are committed to:

  • Listening to you: adequate time to assess your problem.
  • Safe, effective and comfortable GI procedures in the highest quality endoscopy centers
  • Keeping our staff focused on your needs, comfort and on timely access to care
  • Working with carefully chosen physician colleagues, hospitals, radiology and labs
  • Keeping your care as affordable as possible
  • Continuously improving quality in what we know, how we serve you, and in the outcomes of what we do

Welcome to our practice! The doctors and staff of Gastroenterology Associates want to understand the health issues you face and we strive to have our patients be well informed decision makers about their health needs and choices. That's why we've developed a website with lots of valuable information about us, about our medical specialty of gastroenterology, about GI endoscopy, digestive problems and treatments. New information will appear steadily, so visit often!

Our website has the information you need about

  • our physicians and staff
  • office hours, appointment procedures, maps, directions to our office in Pasadena
  • procedures & services we provide
  • the Pasadena Endoscopy Center (PEC)
  • financial policies, insurances we work with
  • and a lot of other useful resources about digestive disorders.

We are committed to making our office practice and our Pasadena Endoscopy Center convenient and accessible. We want you to feel confident that by choosing us, you're working with professionals who are qualified, experienced and caring.

Please take a few moments to look through this site to get a better feel for who we are and what we do. We invite you to email or call our Pasadena office at any time to request an appointment or ask any questions. We invite comments and suggestions to make our practice (and our website) better! Thank you!

New in July 2012, our PATIENT PORTAL will allow you personalized secure access to our practice, to facilitate getting appointments, for your billing and payment questions, and (increasingly) to access your own medical records confidentially.
