I felt very comfortable as a patient of Dr. Greaves. He treated me well. Everything went out, went perfect. He explained everything and so far, we're dealing with the....with the problem, but I have no problems with him whatsoever. The ER staff are great.

Overall, I had a wonderful experience. I cannot at the moment think of the lady that did all my testing before Dr. Greaves came in, but she too was absolutely outstanding. Her customer service, her explaining things, she also was amazing. And I'll be darn, I'm sure it's in my health records of who did all of that before Dr. Greaves came in and I would love for her to be recognized as well. Thank you.

Why are most doctors not available when I need my appointment. Usually more then 3 months out or more to get an appointment. This is becoming my experience with all doctors at PIH. I have a PPO not an HMO.

Staff very friendly

The diffiulty scheduling a return appt. was due to their server being down at the time. This is not usually a problem, I'm sure it will be resolved shortly.

This provider is having to double book appointments. The next appointment that I have is only because I have been double booked. I don't know what can be done to resolve this problem. I had rescheduled this appointment because I gave up waiting for the last appointment after an hour. So no, as much as I respect/like this doctor, recommending him only makes matters worse if they're already double booking.

My father mistakenly hit a 10 and a 1, and he meant to hit the best number that, number four for both of those. There was two at the end, questions here, that he meant to hit four. Absolutely was very satisfied with the Dr. Greaves. Thank you.
November 05, 2021
Very clean, professional, timely, and personable. I'm happy I went. I had my eyes dilated and am an RN. I had trouble driving home so maybe let patients know to have someone drive them home or give them a heads up that the effects could be mild to difficult to see and when or how long the vision will be affected by light
November 04, 2021
We saw Dr. Greaves. He was very nice and polite. He explained the procedure to us. He told us that he would get back to us with a referral. He was very thorough. He took his time, he talk slow and very coherent. Very nice man. Very very nice. I would recommend for everybody.

Yeah, the doctor explained every question I asked him. He's very nice. All this staffs very good and very, and he listened to me, to my questions that I had to ask him. And was very patient, too. He wasn't rushing. So yes, I would definitely recommend him to my family and friends, and which I always say I enjoyed having my PIH, all my PIH doctors that I have been going to. Thank you.
October 28, 2021
Not able to get an appointment when I wanted. Waited 3 months for an appt. Need to add more staff.
October 28, 2021
Didn't have to wait very long, the office girls were very kind and when I was taken back to start the process of getting my eyes checked [name removed] was very kind and explained everything that she was going to do to my eyes. I felt very comfortable there.
October 27, 2021
Yeah, sorry. I really appreciate what the people, what the office did for me. And they they provide a very good, they are very friendly and I like that. They tell me what what is going on. There's a lot of things that I really appreciate. Okay, thank you.

Dr. Giovanni Greaves delivered to me some very bad news. My diagnosis was early on-set of [PHI removed]. I was stunned to hear this and was no longer able to comprehend what the doctor was telling me. I think that it's very important that when delivering such a serious diagnosis the doctor makes sure the patient is understanding the details of the diagnosis. He gave me an order for a special over the counter vitamin to take twice a day. I asked for a prescription for the drug and he argued with me that he doesn't write a prescription for an over the counter drug. I checked with my insurance and I am covered for this over the counter drug BUT I need to have a prescription in order for the claim to be processed. When I called the office the woman who I spoke with recited to me the same argument. When I explained why I needed it fell on deaf ears. [PHI removed]
October 21, 2021
To long of a wait for your appointment after you get there.
October 20, 2021
At first I don't know what to expect, since this is the first time to see him. After the check up I have full trust on him already
October 14, 2021
Considering all of the Covid restrictions, everyone in the office made the appointment as friendly and positive as possible. My technician, [names removed], and Dr. Greaves were both extremely attentive, professional and nice!!
October 11, 2021
Doctor and the staff gave a high level care
October 08, 2021
The best doctor ever. Thank you for taking care of my eyes. I appreciate it. Thank you.
October 08, 2021
The doctor really listened to me.
October 08, 2021
Love PIH doctors!!!
October 04, 2021
Definitely. Dr. Giovanni did a good job on me. He explained everything about my eyes. He said that I had to have my eyes checked on the back, so he did a thorough, good job on me. I liked this Dr very much, and I don't want to, I want to lose him. I would recommend this Dr to anybody. So, again, not a 10, I'd give him a hundred percent. He's one of a ... hell of a Dr. Alrighty. Thanks. See you later. Bye.

Hello. Just wanted to let you guys know it was a little bit to put this appoint with this office and the staff and their service. Our original appointment was for September 24th, and they failed to get the authorization. So we had to move the appointment to October 1st the following week and then they said that we need another [PHI removed] and they didn't bother getting that authorization and they couldn't accommodate any anytime soon because the provider wanted to see it within a week to two weeks but the staff wouldn't accommodate us for one whole month. So we had to call back talk to the office manager, you know, we had a lot of hassling with this office for the last past
October 01, 2021
Very comfortable, and I feel very safe with Dr.Greaves he walks me through the whole feature with me when you get this and I will talk to him anytime. That's all the doctors. There are wonderful. So I was just more contagious or so. Great. Thank you.

My father is [PHI removed]. The doctor explained things very clearly and patiently.
