Glenn Littenberg MD, Pasadena CA

I want to again comment on how wonderful and caring Dr. Littenberg is.
He is there for us every time we have any questions. He is the best Dr.ever!

My interactions with Dr. Littenberg and his entire staff was amazing. Everyone is friendly, respectful, professional and do it with a smile. I recommend his group to all my friends.

Dr. Littenberg makes and unpleasant procedure as pleasant as possible while providing loving care

I've been with Dr. Littenberg since 1987 and I will tell everyone how wonderful he is. He's kind, patient and very thorough. He makes you feel comfortable and is a good listener.

Doctor Littenberg always treated me with the greatest respect and always made me feel comfortable before and during any procedure, he explained what he was going to do and what the procedure incompased. I would recommend him to all my friends.

Dr. Littenberg is my doctor’s doctor and I had high expectation before I visited him. I have seen him for the last six years and he met my expectation. I highly recommend him.

Dr. Littenberg is a kind and caring doctor who listens very well and explains you condition and your options. And then he will do what it takes to get the outcome you want. He is a great doctor and I highly recommend him.

Dr. Littenberg was the only doc (after 3 mis diagnosis in the ER) to figure out that my gallbladder got clogged with “biliary sludge” that was treated with medication. Two years later I’m now off the medication and all is well with my gall bladder. I am eternally grateful to Dr. Littenberg and so is my ex-boyfriend who was also having gallbladder issues that were resolved without needing surgery. In a time where most doctors rush through an appointment and are quick to reach for the scalpel or refer you elsewhere, this man is creme de la creme!

The doctors here are very thorough and always do their best for their patients. Dr. Littenberg also spends a great deal of time with his patients and really listens. I highly recommend this facility.

Dr. Littenberg quickly diagnosed the cause of my health issue and helped me solve it with a change in diet. He took the time to explain things thoroughly and the other staff in his office were friendly and professional.

Absolutely the most thorough and best prepared doctor I have seen in the past 20 years, since I moved back to Los
Angeles from NYC.

A wonderful, caring doctor. After years of severe GERD side effects, Dr. Littenberg is very knowledgeable, and has helped me with my sinus issues and my vocal cords, making it easier for me to breathe and talk. He's very gentle, explains very clearly in a manner that is easy to understand. I recommend him to anyone seeking a ENT doctor

I've been seeing Dr Littenberg for the past 15 years and i couldn't be happier. He takes the time to listen and I feel like he values my input when we discuss treatment options. I've had Crohns for over 30 years and Dr Littenberg is hands down the best doctor I have come across. It's probably not a coincidence that my Crohns has been in control since I've been seeing him. My confidence in Dr Littenberg was confirmed a few years back when i was talking to a family friend who is a liver specialist. We happened to talk about GI issues and I was telling him about my crohns. He was adamant that there were only 1 or 2 high quality GI doctors in the area and wanted to put me in touch with someone he knew and trusted. When he asked who my doctor was I said Dr Littenberg. He smiled and said, that's who i was going to refer you to!

My experience was great everyone was friendly and I did not have to wait long. Dr. Littenburg is fantastic

Dr. Littenberg was very patient and kind, explained what he was suggesting then posted a comprehensive analysis of his recommendations on their patient portal

I tend to be wary about medical doctors. I prefer to go the more natural route but Dr. Littenberg was wonderful. First, he had no judgement about my choices and what I had tried before seeing him on the natural side of things. Then he took his time and listened to me. His treatment plan was appropriate and methodical and I am very happy with my results.

Doctor is very thorough and seems very concerned about my well being. He had a number of suggestions and had me schedule further tests to get to the root of my problem.
He is very competent and plain spoken. Office is pleasant and welcoming. Staff is very professional, friendly and helpful.
Doctor continues to offer suggestions to assist me with my Crohn's to follow up with my continued symptoms he is always prompt.
The staff is always patient with me when trying to assist me with online problems I encounter.

Dr. Littenberg has been taking care of me for over 25 years. If anyone has IBS or microscopic inflammatory colitis he is the one to go to. He also has supplements that will help you. He is just the best physician.

Dr.and staff were very courteous, accommodating and friendly. All in all a positive experience.

Dr. Littennberg is awesome! His follow up outstanding. I am delighted to have been referred to him,
