I would give a high recommendation to this practice and Dr CoffeyJohn 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.

He gave me a choice to go ahead with surgery or not and see how things go. I chose to waylay surgery, and he agreed. That told me he actually does care about his patients, and is more concerened about me, than lining his practices pocket.I'm extremely grateful for having the Digestive Heath Instute in my line up of my personal physicians.

Everybody was polite and when I need to go back, that’s where I will go.Selame S. ★★★★★ I’m a referral coordinator for local practice here in Lansing. As someone that refers patients to Capitol Colorectal daily, I can honestly say that this practice delivers excellent patient care and even better customer service. In the case of urgent/ASAP referrals, the front office staff is extremely efficient and accommodating for our patients. I have to eulogize Aly N in particular...for those urgent referrals, she calls me as soon as our patients are scheduled (or she’ll send an appointment notice for routine referrals), so that our providers are well informed throughout the process. Regardless If they are non par with the patient’s insurance, Aly has not only notified me, but she has given me a list of CRS doctors (in Michigan) that participate with that patient’s insurance just to be sure that patient is ultimately taken care of. In addition to her meticulousness, Aly is positive and quite marvelous to work with!Kelly M. ★★★★★ Brooke Janke has been beyond phenomenal! I've never had any Healthcare worker take the time to listen to me the way she has. She is also incredibly intelligent, I trust her judgement completely!Marla M. ★★★★★ Appreciate the great treatment and professionalism of the staff!Linda B. ★★★★★ I have never had an uncomfortable experience with your company! Dr. Plaehn is OUTSTANDING as is his staff at all the locations where he performs colonoscopies and endoscopies. Please tell Dr. Plaehn I said, “Go Blue” LOL!Julie T. ★★★★★ Dr. Coffey and his staff, in my experience, are the best in the business of Colorectal Surgery. I would not hesitate to share what I've been through with anyone who required these specific surgical procedures.Irish F. ★★★★★ 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. My daughter and I particularly appreciated Nicole’s down to earth demeanor and kind heart. We appreciated Dr Coffey’s skill, honesty and approachability and thoroughness with our questions.Josh D. ★★★★★ Excellent!Dale D. ★★★★★ Johnathan was well prepared prior to my visit. He listened to me during my visit and we came up with a good plan for my next step.Amelia M. ★★★★★ Khadra Mohamed is an excellent PA. She is the first healthcare provider that I feel asks enough questions and truly wants to get to the bottom of the issue. I feel like if the doctor doesn't ask a lot of questions, symptoms can be missed because individuals don't even realize it isn't normal. She takes her time with her patients, asking them questions about every aspect of their health, making you feel listened to. She also continually looks for solutions with testing and medications. You will leave the office feeling more hopeful, than discouraged.Tracy M. ★★★★★ so far i like him a lot . takes things seriously and cares. he doesn’t mess around when he thinks something is wrong unlike the many many Dr’s i have seen in the past .. 10 stars!Tina N. ★★★★★ I love the doctor's in this office and sparrow hospital I will go to no other hospital,and Dorian Jones is an awesome doctorJaime S. ★★★★★ I’ve been to see Dr. Coffey a few times now, including for one surgery (on that note, I found banding to be literal torture— allegedly it isn’t a big deal to some but I’d NEVER go through that again—so ask what the odds are that the banding would be AWFUL & painful vs just going for the surgery (which also was super painful but that’s just the nature of it, and at least it was a pain I could get through) and one screening procedure. I found him to be straightforward (not that he’s overly blunt but just that he’s a straight shooter) and he’s nice, as were all of his staff.Joseph P. ★★★★★ The staff is welcoming & caring. The doctor provided a thorough description of the procedure and results.Cyndi P. ★★★★★ Great experience with staff and my doctor, Dr Ross! They know it's a nerve wracking day for their patients, and they are so kind and respectful.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.lori K. ★★★★★ He is the most caring physician and pays great attention to detail. He listens to the patient and makes sure they get the best care possible. He is one of a kind for surejs_loader
