everyone in the office patient and kind,helpful with any and all questions and concerns.

November 11, 2019 11:00 PM

I do truly like this doctor. He is very nice and caring. But, you have to wait up to an hour before you see him. He really does not discuss or ask how I am doing or how much about the pain i am experiencing. Talks about other things. which is nice but, I leave never really getting my questions answered. I do like him and I think he really knows what he is doing. I just need more help & answers to my issues.

November 11, 2019 11:00 PM

To long of a wait time! Always over an hour!!!!

November 11, 2019 11:00 PM

very knowledgeable and easy to speak with

November 11, 2019 11:00 PM

very good experience

November 11, 2019 9:30 PM

I know he's normally running behind because he tries togive his patient's as much of his time he can but they cram in the patient's and he can only do so much.

November 11, 2019 9:30 PM

he always listens to what I have to say even when he's running behind, he never makes me feel like I'm being rushed out of the office.

November 10, 2019 11:00 PM

Dr. Onwuta is the consummate professional. He displays care, compassion, knowledge and understanding. He treats me with respect and always values my opinions. He is one of my favorite doctors and I always look forward to our appointments!

November 3, 2019 6:00 PM

Dr Onwuta and his entire staff have always been great! The receptionist at the Algonquin office is very kind and understanding. the nurses at that location are great as well. Dr Onwuta has always been a great listener and keeps in mind both what is good for me as the patient using my input, and what is best for me with his medical expertise. The only negative experience I have ever had at his office was when I had a couple visits with the nurse practitioner. She would not listen to me nearly as well as the dr and his staff, and seemed to have an agenda of her own, rather than treating the patient.

October 25, 2019 7:00 PM

It is always the best

October 21, 2019 7:00 PM

Dr Onwuta looks over my health history at each visit, and he is never in a hurry to finish the appointment.

October 18, 2019 7:00 PM

this was a good visit. problems were discussed and solutions suggested

October 17, 2019 7:00 PM

It was rushed, but I was told about that in advance & the reason it would be that.

October 13, 2019 7:00 PM

It is always a pleasant time when I have my appointments.

September 27, 2019 7:00 PM

As usual the doc takes a genuine interest in me and my health

September 22, 2019 7:00 PM

Dr. Onwuta is the best.

September 22, 2019 7:00 PM

always lifts my spirits and listens better than any other provider I've used in the past.

September 17, 2019 7:00 PM

Dr. Onwuta is fabulous. Remembers conversations from previous visit and REALLY listens. He looks at my whole picture, not just one segment.

September 13, 2019 7:00 PM

always nice

September 9, 2019 7:00 PM

Dr Onwuta is a wonderful doctor. His concern for my illnesses and treatment was discussed thoroughly -without me feeling as if he's rushing to the next patient. Dr Onwuta is a Pain Mgmt Specialist I had switched from Dr X who DID NOT hear my concerns nor read my list of illnesses. Dr Onwuta made me feel we would work together for a positive goal and outcome.

August 14, 2019 7:00 PM

dr. Onwuta is understanding and listens to what you say and ask. He has done procedures on me and I've seen the respect the assistants have for him no mater where it's done. that tells a lot. any questions my wife or I have he answeres. I've heard others in the waiting room say how they like him. He's been good for me and my family he really cares about his paitants!

August 13, 2019 7:00 PM

My experience has always been great with Dr. Onwuta.

August 12, 2019 7:00 PM

dr was very kind and i liked him he was surprised i had to wait 7 weeks to see him
