Dr. Littenberg had clearly reviewed my condition prior to our meeting. He was courteous, pleasant, well-inofrmed, caring and thorough. He paid attention to what I had to say and provided convincing / complete answers to my questions. Following the two procedures / tests he recommended, he called in a timely fashion and explained the results carefully and patiently. Within a few minutes after the phone conversation, I received the written reports. A gratifying experience.

Dr. Littenberg is a fantastic listener and does not rush his patients. He is thoughtful, pragmatic and highly effective which are a few of the reasons he is in such high demand. I recommend Dr. Littenberg without reservation.

I had a hard time getting an appointment , I was scheduled a month later. Once I got in, the regustration was done smoothly and above all the Dr. Littenberg was extremely thorough.
Dear Maryam, We truly apologize that our time to schedule you in for an appointment was so long. We are happy to have seen you and hope to help you with your GI needs in any way we can!

Dr Littenberg is the best. I've been seeing him for my Crohns condition for the last 15 years or so. During that time he continually impresses my with his expertise, knowledge, and compassionate nature. He is easy to talk to and takes the time to listen and explain my options. I never feel hesitant to ask him a question and he always has great advice. I couldn't be happier.
Alhambra, CA |
I like that he's very detailed (all n notes go into his computer), asks lots of questions and listens! Great bedside manners. Comes highly recommended by my other doctors.
in Arcadia, CA |
'What can I say that I already haven't about Dr. Littenberg. My husband and I have been with Dr. Littenberg for 28 years and we have never known him to be anything but professional, compassionate, and caring. Oh I forgot to say extremely patient. He makes you feel like he's known you forever and I have to remember to call him Dr. Littenberg not Glenn although after all these years I don't think he would care.
Pasadena, CA |
Generous with his time and knowledge. Willing to listen and propose alternatives. This is a dictor who spends time thinking through problems and trying to find appropriate treatment. He is also well-connected in the gastro area with access to trial medications. In addition, he's a nice guy with a photography hobby ??

Dr. Littenberg can save your life. He stopped cancer several times in my Dad ( as well as helping reverse the effects of nerve damage from neurotoxin exposure in Viet Nam) and had insisted I get a colonospopy and did find a polyp in a part of the colon where most " normal" doctors seldom bother looking. He is a genius in every way. He can make the scope do things no other doctor can to He is what every doctor should be and what every human should try to be. Trust your life to him... believe me
