Very pleasant and professional. Detailed and accurate.
FYI Dr. Li's office has about 10 doctors. You are very likely to see someone else rather than Dr. Li himself.
Very professional , the office is small and a lot of people but I did not wait long.
Busy yet efficient office. Staff are fast, friendly and professional.
Dr. Li was highly professional but at the same time very friendly and accesible. I would definitely recommend him.
Dr. Li has a very busy practice, but his office staff is efficient and pleasant. I knew I would have to wait, so I was prepared with a book and it didn't bother me. He is pleasant. He squeezed my husband in for a colonoscopy in 2 days which was great. I will turn to him again in a few years when I am due for another check up.
Office staff very helpful and professional. Running mostly on schedule. I didn't wait a lot of time in the waiting room before being seen. Dr Li was very professional, took the time to explain his prognosis, outlined a diagnostic plan, and answered my questions. He has a great demeanor, and good communication. Would highly recommend.
Dr. Li paid attention while I was explaining, he planned very well for my next visit. The office people are very nice and efficient, they are friendly, too. So, I will wait till my next visit to find out more about the doctor.
*Very* busy, crowded office, but my wait was very reasonable, considering the number in the waiting room, and everyone was at the height of professionalism. I highly recommend them!
Had a very nice experience with the doctor. Very understanding and easy to talk.
Excellent doctor. Very knowledgeable, compassionate, and easy to speak with.
Dr. Jianjun Li was nice enough, but it kind of seemed like he wasn't really listening very closely to my problems, and it kind of seemed like everyone in his office was being signed up for colonoscopies. I did end up switching to another doctor who takes better care of me. Also, the office is cash only, which is pretty annoying.
Wouldn't allow me to hear my results of a test over the phone so I had to find time to come in to hear a yes or no response.
He was nice and listened but he was very busy and I felt very rushed.
I had to find a specialist at the last minute. Was thrilled he has Saturday hours. Waiting room full but kept moving. He apologized and so did his friendly staff for running overtime. He had to do a procedure that took longer than normal. I felt comfortable with him and he was thorough. He will be doing two procedures on me.
Was very helpful and friendly and professional..
He was the ONLY GI I saw in 4 years willing to order a CT scan. And the scan showed something. He pinpointed ONE problem and discussed the method of treatment. His office staff made it easy to get a copy of my report. Very busy office. On the Other hand..he missed a major infection going on by NOT ordering a culture analysis . I had to see a second GI to be tested and I tested positive.
Dr. Li was fantastic. Dr. Li just met me for the first time and it was for a last-minute prescription I needed while out of town, and yet he was obviously feeling empathy and wishing he could do more to help - and he was encouraging too! A positive guy. The waiting room could be improved and the front desk staff weren't super friendly, but they were efficient.
I had a good visit with Dr. Li. He had a really great bedside manner and he was really nice. I was brought in shortly after I signed in. He was very quick in diagnosing what I had. I was very amazed! I will be coming back here for sure!
Nice, thorough... Explained everything in the consultation
he was very nice and respectful I would definitely go see him again
Very helpful and reassuring, answered my questions and gave thorough explanations. Great doctor, would definitely return and advise him to others!
It was good
He didn't waste time, he could tell you what is the next procedure right away. I am glad to have him taking care of my mom.
It was pleasant and they answered all my concerns.
It was a great visit. Everyone in the clinic is nice and friendly. Dr. Li is very informative.
Dr. Li is a very experienced gastro with very good bedside manner. Wait time can be a little long sometimes tho.
The visit was not too bad. This was my first time there and both the staff and the doctor treated me politely. I will be returning for a second visit soon. So far so good, no complaints.
very thorough! he really listened to me and regarded my opinions....very rare in a doctor!
he fixed my problem
I saw Dr. Tin at the clinic and he was one of the best physician I have ever seen. I was very impressed at how he explained every little thing as to why I might be facing a certain problem, the physiology behind it and what treatment options are available. I would highly recommend Dr. Tin to anyone who is looking to get complete attention from their doctors, so they can make a better decision about their health!!
Great staff, thanks.
Great bedside manners
