I was sent for a referral for possible surgery on a lipoma in my intestine… After meeting with Dr Coffey and discussing my case and options I was relieved to know surgery wasn’t really a necessity at this time …I had many questions about my issues which he very professionally addressed in terms that were understandable to me … office and staff were warm friendly and professional…. I would give a high recommendation to this practice and Dr Coffey
Ray A.
It is always a great experience, start to finish. The wait time is reasonable. Jonathon Thelen, the PA I see, is EXCELLENT. That guy gets it done and done well. He is always friendly and makes good small talk while dealing with the biz of my twice-yearly check-ins.

John C
I've have had three, if I remember correctly, Colonoscopies and an endoscopy in the last 20 years with Dr. Yusuf. I found him to be very nice and the procedures went without a problem. In addition he prescribed Omeprazole when it was first coming out, before it could be found over the counter. My esophagus was pitted and damaged from GERD. His prescription was life changing for me. At last it didn't feel like I was burping lava all day long.
Mona D.
All very efficient, and kind. Dr. Julien is thorough and takes time to make you relaxed and comfortable.
Lori K.
Staff prepped me for my procedure without rushing.They obviously had to keep to a schedule. Very comfortable environment.

Cherrye Marchelle M.
He has been my doctor since 1995 when he first started his business inmuch smaller office.I have 3 other family members that also go to him now that I referred them to Dr.Ross. Everyone one of us loves him.I refuse family members to see him for their troubles like I have. He is the best in the Lansing area.
Anita S.
Everyone there is so nice and the Dr. Is very thorough. I highly recommend them.
Krista Jo L.
Dr. Yusuf was very thorough and made me confident that he was checking my gastro system completely so I could relax about this area of my health.
Bonnie G.
Due to several detours on the way to my appointment, I was 5 minutes late, however, I was treated courteously and was ushered in to see the PA fairly quickly. The PA, whom I specifically made the appointment with, listened attentively to me, asked questions, and took copious notes. Before I left, I had a prescription and a date for two procedures. The person who scheduled the future appointment was very efficient and friendly, and explained everything in full. If you are searching for a gastroenterologist, Digestive Health Institute is the place to go. I've been there several times and it's always been a positive experience. Also, it's easy to get to--except for the several detours I encountered the day I went!
Jackie H.
Staff were courteous and attentive. Provided atmosphere to be totally calm and comfortable!!!
Paul G.

Lynn B.
Everyone (the physician and staff) was wonderful! They were professional, kind, and efficient.
Debbie S.
It was very lovely. Very efficient staff. I felt cared for and valued. My procedure was seamless, mostly because I was not aware of the procedure at all due to the excellent anesthetist. All in all a very good day, I felt like I was at a lovely Spa. Dr Julian is a very nice and talented Dr.
Candis R.
I was in rather desperate need for a new GI doctor, and I could not be more pleased with Dr. Jones, his PA, Jonathan, and the rest of the staff.
Jasmine S.
I always get the care I need to the fullest and the doctor makes sure I understand things correctly
S M.
Nice people. Quick procedures.
Mrs. O.
Obviously we wish we never would’ve had to have a visit here, but the staff made a terrible situation better through their expertise, kindness, empathy and honesty.
