This was the first appointment with Dr. Auo as my new health care provider. I was very impressed with his knowledge and interest in my questions and concerns.
Providence Patient
Very happy with Dr. Ao
Providence Patient
Please have the provider to see the patiences on time. & Don't let patience ask the test results, then they go to check the details. Thanks.
Providence Patient
I always have good experiences.
Providence Patient
Dr. Aou is my PCP for years, he and his staff are always very professional and friendly. If anything I can suggest is that St Jude heritage group can make Dr. Aou more available. So far, it take me 2-3 months to make one appointment to see my PCP, Dr. Aou
Providence Patient
I was able to see this doctor due to him having had a cancellation I was thankful he was there and could alleviate any concern I had with the issue we discussed.
Providence Patient
This is the first time I saw Dr. Aou. My last doctor was Dr. Benoit, but he transferred to the executive staff. But my insurance told me that Dr. Aou was my new doctor, and it's the same address that Dr. Benoit had. No change! He recommended that I get the Shingles vaccine & also that I get a tetanus shot because It was over 10 years since I got my last one. I'm very happy with Dr. Aou, and I'll see him every year for my annual check up!
Providence Patient
Had a great experience with Dr Aou. So patient, took the time to listen to me.
Providence Patient
Dr. Aou is very details and professional physician. This is my first time to visit him. I was referring by a nurse from Dr. Dolkar's office. His staffs are very helpful and responsible.
Providence Patient
My care provider is very good explaining things nicely and listen to patient properly.i like him very much and will recommend my other friends and relatives.
Providence Patient
Great care
Providence Patient
Did not send any information over on which stretches to do and did not give much information
Providence Patient
Dr. Oa was very respectful, caring and took time to listen to my concerns
Providence Patient
I like the care I get from Dr Aou and his staff.
Providence Patient
Dr. Oau, after palping the two lumps in my neck, stated that he would prescribe an ultrasound to ensure that those lumps are non-serious growths. I appreciate his cautious approach.
Providence Patient
Dr Aou caring person he really listens to what is being said. I trust him completely, not only is he my doctor he is my friend.
Providence Patient

Providence Patient
Good
Providence Patient
This time it was easy to get to see doctor. In the past especially about 8 months ago it was impossible to get the attention I needed
Providence Patient
I didn't know the doctor at all. I do have an appointment with the doctor I'm going to ask to be my primary. And the appointment was to ask about a different medication. But I had gotten so sick that's all we could talk about. By the way I couldn't even breathe in enough to talk. I can't believe it I have four phone appointments on the United healthcare line or those virtual things. They kept saying I didn't need medicine I was like you don't know what you're talking about. I got to this doctor he spoke to me for a few minutes he listened to my chest he ordered it x-ray he gave me the correct medicine. He explained how to take it. He asked me if I understood and explained very well with that because I know that medication can be challenging. I'm getting well because of the doctor. And the doctor sent me a message to call the pulmonologist. He was a little bit distant and reserved but he was a very efficient for what the situation was. I hope he knows I was trying to send him something saying thank you. Oh and also to please hope I don't need the antibiotics because I finished it when I was on. I think I'm more well I'm not calling begging him yet so I think I'm more well and the medicine he prescribes working well thank you doctor
Providence Patient
Dr Aou was very responsive to needs and request.
Providence Patient
Dr Aou listened to my request and fulfilled it
Providence Patient
I appreciate that Dr. Aou expresses concern and interest in my wellbeing.
Providence Patient
Dr. Aou has been my primary doctor for over 15 years. He is professional and pays attention to patient's records. He is excellent doctor.
Providence Patient
We always review any blood work that we are following for improvement and review meds as needed.
Providence Patient
The Dr should ask more questions, show a little interest in my concerns, attempt to provide the possible reasoning for my concerns and explain why he ordered the minimal bloodwork he put in for. I asked for full labs as I've been very ill for months now. They were never reviewed and never followed up. Now I have to reach out and complain which is absolutely unprofessional and unfair. I have three kids, I work full time and this experience was pointless. Now I have to reach out to my Dr who is booked months in advance to remedy this situation that was not his fault. Now I have to wait even longer while feeling ill to try to get help. Disappointed.
Providence Patient
The services were excellent by everyone
Providence Patient
My experience in all my visits was excellent. I am very happy with all my physicians.
Providence Patient
The staff was very nice and helpful. As for the provider, I have never felt judged and uncomfortable as much as I did by that provider. My decision on how I wanted to proceed seemed against the provider's wishes and kept insinuating I change my mind.
Providence Patient
I like that Dr Aou has been our Dr for 25+ years and knows both my husband and I very well. He is caring and concerned.
Providence Patient
Immediately welcoming with a greeting and natural smile. Listened attentively, showed interest in and respected my feelings about my health care. Not aggressive or opinionated. For me this was great!
Providence Patient
Good
Providence Patient
Dr Aou is a very good doctor who provides good advice like he would do for his own family
Providence Patient
Very Good .
Providence Patient
Dr. Benoit has been my Primary Care Physician and his advancement necessitated the change. Dr. Aou was exactly what "the Dr. Ordered!" I left knowing that I have found a great Dr for my wife and me.
Providence Patient
I have had nothing but great visits with Dr. Chris. He's fantastic!
Providence Patient
Very nice + caring + very helpful + very easy to communicate
Providence Patient
Good
Providence Patient
Did not feel that he was listening to me or understand what my problem was would not go to him again
Providence Patient
Dr.Aou is caring, understanding, and knowledgeable. I consider him not just as my doctor but a very caring friend.
Providence Patient
Good experience,
Providence Patient
Dr. Aou is a very good "family doctor", The downside of that is that it sometimes takes a long time to get or reschedule an appointment.
Providence Patient
Everything is good. I have been seen by St. Jude Heritage Medical for a very long time. I will always be yours patient thank you for everything.
Providence Patient
I love Dr Aou. He's the best doctor I've ever had.
Providence Patient
Good
Providence Patient
It was extremely helpful to have the video visit. It would have been very difficult to go to urgent care.
Providence Patient
Dr. Aou and his staff are very professional, knowledgeable and helpful.
Providence Patient
Wonderful doctor nice and the patient
Providence Patient
I'm tired of this providers office. You can't get an appointment usually within two weeks. If you want to see him you need a video appointment and you can usually get that within two weeks but the aftercare I'm done. I don't want to see this provider. I am again, and I am looking for a new provider. The aftercare on this appointment has irritated me to no end. They've discovered I've got a new condition and I'm not getting any assistance with it what I was told as I've had this for a while and that's kind of it. I'm done with being told I've had the condition for a while, I'm just done
Providence Patient
I love St. Jude, very professional provider and staff. Very respectful people. I was seen right away.
Providence Patient
Good
Providence Patient
Given the obvious patient volume that primary doctors handle, I feel that I am receiving the care that I need.
Providence Patient
This Dr is a great addition to this practice
Providence Patient
Always professional.
Providence Patient
Very good
Providence Patient
I am with Dr. Aou several years already, he is the best family doctor I have met.
Providence Patient
Very good experience with dr Christopher ove
Providence Patient
I'm changing my primary to the aforementioned physician. That should say it all!
Providence Patient
I now plan to call Dr. Aou's office about test results and any necessary follow ups.
Providence Patient
The provider was very respectful of my questions and took time to explain them to me.
Providence Patient
Good
Providence Patient
Takes to along to get an appointment
Providence Patient
MA was very upbeat and friendly. Dr Aou as always was through!
Providence Patient
I love Dr Aou. He is very kind and patient. He listens to my concerns and takes my wishes into consideration.
Providence Patient
They always listen and you never feel like you don't matter!
Providence Patient
Dr. Aou has always been kind and understanding about my health issues. He does referrals out to a specialist when one needs to be consulted on a heath issue.
Providence Patient
First attempt to make an appointment would've been almost two months out to see a Dr. Thankfully, the scheduler said she would ask the dr's nurse to call me if there was an earlier appointment available. I received a phone call back the same day and was able to make an appointment much sooner. That was great customer service!
Providence Patient
He has been my provider for about 20 years and is the best.
Providence Patient
Every thing was satisfactory.
Providence Patient
At age 57, Dr. Aou is the best doctor I've ever had. I love St. Jude.
Providence Patient
I love this doctor but this time he made me wait too long in the room also I felt like he was rushing coudn't talk to him a lot about my concerns and health.
Providence Patient
I am very satisfied with all. Well done.
Providence Patient
Good thanks
Providence Patient
He was late
Providence Patient
I waited 30 minutes after the appointment time for a 5 minute consultation.
Providence Patient
The nurses and doctor Aho seam very customer oriented and answer all questions.
Providence Patient
Dr. Aou is an excellent, caring physician.
Providence Patient
Doctor is the BEST
Providence Patient
Grateful they made the time for us.
