Dr. Jonathan Sack, MD

He gave the most thorough and professional care. Dr. Sack explained the purpose of surgical paths with compassion and empathy. I was blessed to have him as a provider of my surgical and post care in year 2012. Although he will be missed within the UCLA world, he left a positive improvement to the lives of so many both professionally in his office and personally for the quality of life to his patients. It was a privilege and blessing for me that he crossed my path when he was needed.

he is wonderful , he is my Dr for about 15 years , last month i called for appointment i find out he is retired. he saved my life and many others i didn’t have chance to thanks him. thank you and i never forget you . you will be always in my prayers.

Dr. Sack, you are the best at what you do and we are so grateful to your expertise and knowledge of Crohn's Disease. Thank you for all you have done for our son.

Actually I tried to get an apapointment with Dr Sack for my father since 4 months ago and still they did not give me any appontment and still waiting, but his taff which her name Temike is so rude and does not care about the patient and they lost my father medical reports 2 times and always they denied, so I am so disaapointed and give up.

This doctor is unprofessional, rude, and full of himself. Avoid. Other colorectal surgeons at UCLA much better.

Dr. Sack really listens and takes his time. Always feel like he really cares. He makes me feel like there is nowhere more important in the world for him to be when he's seeing me. He answers every question, no matter how many I have. I've never felt like a number. Easily the best doctor I have ever, ever seen. He performed 2 successful surgeries on me. I am still on the the road to recovery, but I have full confidence that I will soon be feeling better than I have in years. Going to Dr. Sack is the 3rd best thing I have ever done in my life (after marrying my husband and having my children)! After my 2nd surgery I really wanted to hug him, but that probably would have been weird. I really cant thank him enough though, he has been a gift from Heaven!

The best colon surgeon in America, bar none. Saved my life and that of several others I know. Caring, compassionate, always on call and always has time for his patients. Follows up in person and truly cares. Plus he is enormously skilled as a surgeon and can do things even when others say it is impossible. If you need colon or rectal surgery there is no-one better than Dr Sack.

Honestly the most competent easy to talk to nicest Dr. I've EVER met. My oncologist told me that Dr Sack was one of 2 surgeons in the country that would even attempt my surgery let alone do it successfully. His bed side manner is remarkable. He came to my room every day and sat down and talked. I never felt rushed. We talked about my case but also about life, kids, wives etc. 20-30 minutes Everyday. I had a post op follow up with the plastic surgeon and Dr. Sack actually worked his schedule around that appointment so that he could say hello and not have me drive back to ucla another time. He saved my life. He's a great man and Dr.

There are doctors, and then there are those old-fashioned, caring doctors, competent, but modest and unaffected by their egos... Dr. Sack is definitely one of them. My son needed a very specialized type of surgery, that only a handful of colorectal surgeons are either able or willing to engage in. Dr. Sack was both, and a godsend as such. He also took painstaking care of my son in the weeks following his surgery, and as a result, it was a success. His patience, positive attitude, and overall bedside manners are exemplary. Can't thank him enough, and can't give him enough kudos for the manner in which he fulfilled his Hippocratic Oath towards us. I can only hope other doctors can take his example.

A life-saving wonderful doctor who cannot be recommended highly enough.
