Cynthia D.

Dr Opreanu and staff are great! Professional and caring and helpful.

Dale N.

If one can “love” a colonoscopy then combining the new prep protocol for Golytely, Dr. Phlaen, and Lansing Surgical Cener is the way to do it. On time, well organized systems (check-in, check med history, vitals, introductions, and concise descriptions), and complete checkout with photos and road map to the entire procedure. Could not give a higher rating. Simply the best yet!

Joseph M.

Staff was kind and very professional.

Mark S.

Dr. Yusuf is a terrific physician, providing excellent specialty care. The office itself is a little cramped and dated, but the staff is efficient and I’ve never waited too long to be seen. Recommend this group and especially Dr. Yusuf.

Michael B.

Easy in and easy out. Very efficient from start to finish and staff is cool.

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.

Qiana Green S.

Everyone is super nice and informative. Dr. Opreanu is fantastic!

tom R.

Very nice place to have a procedure done all the staf were wonderful great experience

Andrea was a great listener. I’m confident that she took accurate notes and she seemed to care about my thoughts

Charlie S

I am so happy to have crossed paths with Dr. Julien at the DHI. His expertise is comprehensive and he is empathetic. He provided perspective and treatment that has greatly helped me move toward completion of my recovery from a procedure done at a different facility. I am going to spare you the details, the photos and the videos...
