What They Are Saying
Highly recommend this office .
Leslie Croo
But, what impressed me was the staff in the office. The TEAM (receptionist, the nurse who checked me and made me ready for the procedure, Anesthesiologist and nurse in the procedure room, the recovery room nurse, the PA who called me later in the day to check-up on me) showed me such care and compassion. It made me feel as if I was the most important patient that they would encounter.
It is obvious that these professionals love what they are doing. They love helping others. That made all the difference to me.
Thank you.
The office staff is extremely nice, helpful and very caring.
My husband and I are both patients. We highly recommend Center for Digestive Health
Upon arrival at the clinic, my paperwork was processed very quickly, and I was guided into the exam room for preparation.
The staff members were friendly and professional. I am very grateful to all of them and especially to Dr. Donat for his expertise.
In addition, the results of my colonoscopy were provided within 24 hours.
I truly appreciate your attention to detail and compassionate approach, and I would not hesitate to recommend your practice to others seeking high-quality care.
Thank you again for everything you do.
Each staff member were very professional in their duties.
I would refer all my family and friends to come here . Great place I believe I’ve been coming here for the last 15 years were needed
All around, their staff was kind, friendly, just great. Thank you Dr. Nandi and crew!
Explain everything well take time with you. All staff Front desk and medical assistant are helpful and great. Highly recommend this office.
The front office staff and scheduling staff are always pleasant.
I'll still return to see my doctor because I don't hold him responsible for the incompetency of his staff.
Furthermore, why couldn't I just start paying my balance on the new ridiculous bill you were going to charge, which I don't think is fully accurate? Instead I paid off the $432 to collections because I HAD to, they say, before they can schedule me. The outstanding bill, btw, was from Pinnacle anesthesia because apparently anesthesia is not covered for an endoscopic procedure. Weird. I guess I could schedule my endoscopy and we can talk about me staying awake for it? Does that get me a discount?!?
Then, THEN, I call the collections company and I paid my full balance they gave me, but THEN the office says the billing company got the number wrong and I still owe $107 after paying over $400. Again, I HAVE to pay the debt they already sold to collections before they will help. Their mistake is preventing me from getting help. And the collections agency doesn't know what I owe. I'm being held captive by the incompetency of this billing team. I called Monday and still waiting on a call back. It's Friday.
This has happened to me before here, and I paid the bill off at once then too. I actually offer copays, check my balance ANYTIME I've been in the office. Just because you guys are awful at your job and don't bill properly or timely doesn't mean I should have to suffer.
Holding me captive over a balance in collections that I paid on 8/06, per my credit receipt.
When I asked about my balance in person at my colonoscopy, remember it was $0. I have not been seen since. Yet my bills are from prior to that!
Seriously too, they could've told me my balance before my tele health visit with my doctor. Or the 4 times I scheduled a telehealth this year and got canceled on multiple times by you guys. At ANY point you could have let me know my balance. I also could have opened my mail- I get it- but you could also just be competent at your JOB. I don't get paid for opening my mail. You are getting paid to do your job right.
Dr. Nandi- ⭐️⭐️⭐️⭐️⭐️
Office staff- 🌪
*Update: Rescheduled at their other office although it was after I already figured out my own problem and got it under control myself. Had the endoscopy at Macomb anyway, and it went really smooth. Dr. Nandi is so understanding, and listened when I explained I think I was having a reaction to a medication I was taking. He is honestly great enough to deal with a couple bad apple staff members. Most of the team is great.
Honestly, I don't even entirely blame the billing staff- I blame their system. The people were nice enough, they just don't know how to get everything figured out due to too many hands in the pot. Just be cautious.
Jessica listened to my concerns and was very helpful . She explained things to me that I could understand .
Excellent aftercare as well, called to make sure I’m doing ok later in the afternoon.
I again highly recommend Dr Wille. He cares, he's patient & thorough. I cannot express enough how wonderful Reneshia (nurse in scheduling) was. This event was extremely difficult for me & she calmed & reassured me all would be well. Thank you for having her in your practice!
Thank you to everyone!
I can imagine that the medical profession is very demanding and I've been in offices where the Dr's have been short and barely stay in the room 2 minutes and I'm left with more questions than I walked in with but not with Dr Webber, I was the last appointment of the day and I'm sure he was ready for his day to be over but he stayed in there and answered every question that I had and was so kind and caring.
I highly recommend Dr Weber and his staff which were also completely amazing.
Thank you for showing that you actually care about your patients.
My husband and I are both patients. We highly recommend Center for Digestive Health
