Patient Reviews

June 09, 2021
It takes too long to get appointments
June 09, 2021
Wish it could have been sooner.
June 07, 2021
Wait to see him 1-1/2 hrs Needs to schedule patients differently. Wait too long
June 07, 2021
I was treated with sympathy, with professionalism and with respect a patient couldn't ask for more than that. I think the office and the doctor and the way they conduct them selves in a professional manner so my needs and your needs as well.
June 07, 2021
Everything went smoothly, quickly, and everyone was very pleasant to speak with.
May 28, 2021
Seems as appointments where over booked. Took quite a while to see doctor after initial testing
May 27, 2021
This office was more relaxed and professional, the clerk at the front was kind and professional, same as the doctor's assistant. I want to continue visiting this office when needed. Thanks
May 26, 2021
The doctor was so nice. I really feel like he cared about me and what I am concerned about. His bedside manner was great. I felt really good after seeing him. I just felt like he care as much about my health as I did. Great doctor! Will recommend to everyone I know.
May 25, 2021
The doctor did a very thorough exam and was courteous and knowledgeable
May 20, 2021
The scheduling phone office sent me to the wrong office If I hadn't been early I would have missed my apt.time. ?
May 20, 2021
Dr Greaves was very professional, careful in his explanations, and listened to my questions and answered them. It was a good experience.
May 18, 2021
I would just like PIH to provide an eye doctor closer to the Montebello area. Thank you.
May 12, 2021
Great experience !!
May 11, 2021
I felt that the booking lead time of greater than 8 weeks to see a specialist exceeded any medical standard. No patient should have to wait more than 3 weeks to see any specialist and PIH consistently exceeds the 8 week wait time with almost all its specialist providers. I suggest that if you intend to grow and expand that you do a better job of increasing the number of specialists you employ to meet the need of your patient load until you reach the 3 maximum booking lead time
May 11, 2021
All in all,Great!
May 06, 2021
Dr. Greaves' excellent exam was very thorough and alleviated all my concerns.
April 30, 2021
Please note that all of a sudden it's become near impossible to make an appointment I'm on hold for 20 minutes waiting to speak to somebody and that is not acceptable and that's with all the doctors that I use again the the clientele that you have either a very slow or you cut back on your staff because making an appointment is horrible thank you.
April 29, 2021
I appreciate your kind attention.
April 26, 2021
It was a great experience. Very very, very professional. Thank you very much.
April 26, 2021

My office visit was not through a normal appointment but through concern my posterior vitreous condition recently experienced could be causing a retinal tear. The office staff enabled me to see Dr. Greaves on an emergency basis for which I am very grateful. Thankfully my concern was due to an infection of the eyelid. My experiences with PIH Eye Care has been the very best.

March 22, 2021
Hello. I'm not very satisfied because he gives me appointments very withdrawn and I have my bad eyes, last year they canceled the appointment, I do not know what the reason is, but I would like to see another eye doctor. Okay thank you.
March 22, 2021
The doctor is very cordial and professional, but the receptionist did not help me, and she was not friendly when I asked her why they kept me waiting so long, they made me wait two hours, and they attended to people who arrived before me, it was very frustrating
March 17, 2021
For me he has always been very kind, and very very attentive, and I would recommend him to other people and my family.
March 17, 2021
My health is improving and they showed happiness about that. Very encouraging and real caring.
March 16, 2021
The experience was great. I had a meeting following the appointment, so was a little worried that I would not be able to get out in time, but everything was great and I made it easily. I would recommend this office and doctor to anyone.

Dr. Greaves was so kind and knowledgeable! Great experience.
January 29, 2021
Yes, I didn't have a very good experience. This is the first time I see this doctor and there was a very poor communication. I'm sure he's a fine doctor but his communication skills are very poor. I had to ask many many questions otherwise, I would have walked out with 0 information. The process was not explained to me. My diagnosis was not explained to me as had been explained to me by the previous doctor. I have been in this office for years. I would like and I would request to see another doctor concerning the same visit, if somebody if another doctor could please see me and go over the information.
January 14, 2021
It was all very pleasant
January 12, 2021

January 12, 2021
This is one doctor on top of his game he has won my confidence and respect
January 11, 2021
I went to see Dr. Greaves to get a second opinion on cataract surgery. My former ophthalmologist retired, the office has become a clinic, the Dr. did a hard sell on an expensive lens. I was uncomfortable with how it was handled. Dr. Greaves was patient, listened, and I am now waiting to schedule surgery. Thank you Dr. Greaves and PIH!
January 07, 2021
When I was looked at, I was the first one that the lobby waiting for my name to be called or proceed Optometrist and I was ahead on the second one 10 minutes. But my name was never called, people bypassed me. And I'd like waiting there for almost about an hour and my name is still not calling and I have to pick up my wife , I had to drive to downtown Atlanta to pick up my wife and that's why I left. When I get downtown I got a call,they're looking for me and it took it about almost 5 o'clock. So when I called back so obviously the office was closed. I was expecting a call back there.
January 07, 2021
Dr. Greaves and Staff are always polite, patient, and very respectful. They always listen to what my mother and I have to say. Enjoy being a patient here.

December 09, 2020
In my past visits with other opthamologists in this practice I was treated as a "data input" - the doctor rarely looked up from their computer or addressed me eye to eye.Dr. Greaves was engaging, answered my questions, told me what he was doing and why with every test and informed me of a possible nerve condition that the previous doctor noted but never mentioned to me.I will definitely recommend Dr. Greaves.
