I had a great experience with my visit with Dr Giovanni Greaves and all the staff that saw. Everyone was extremely courteous and helpful. Check in was quick and easy. It was great. I was given papers to complete as a new patient to that facility while Dr Greaves prepared for me. My information was submitted on the computer by the staff. I could ask any questions. All staff were knowledgeable and very helpful. Dr. Greaves examined my eyes very thoroughly and explained my situation and what was needed. He was wonderful. Pictures were taken of a problem area on my eye to compare on future visits: I was provided with the schedulers information that schedules surgery. I feel very confident that Dr Greaves or an associate will take care of my eyes and complete the necessary surgery. I definitely will recommend Dr Greaves and the staff to friends and family.

Dr. Greaves has been my Ophthalmologist for 2-1/2 years. He actively listens to your questions/concerns. He is personable, thorough and thoughtful. Dr. Greaves is the consummate professional. This was my first visit to the La Habra location. I was pleased with the professionalism of the staff at this location. While parking was an issue, I may schedule future appointments at this location.

August 27, 2021
My purpose for this appointment was to establish a baseline of my eye-health, so that they will last as long as I do. All technical issues were explained in language I could clearly understand. The doctor's focus was completely on my interest, without a bunch of side issues taking up time. I was treated courteously and efficiently. A very good session.
August 27, 2021
Everyone was respectful nice very Pleasantly good experience
August 26, 2021
They gave me no warning that they were going to dilate my eyes. When I walked out of there, I had to sit in my car for 45 minutes because I could not see. I stumbled into the sunlight and I just... I could not see, literally had to put my hands all over my face, my eyes, because it was difficult to see.
August 26, 2021
Everything was very good. But now I have to leave the service because you do not carry the medicine I need for my eye injections. So that is the biggest bummer of it all. Otherwise in that I wish you did. That's it. Other than that, it's perfect. Thank you.
August 26, 2021
Dr. Greaves was very gracious, answered all my questions, and gave me a good report on my eyes present condition. I look forward to seeing him in a year.

The technician who took me into the office and had me complete some tests was extremely nice!!!

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 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
They need me to make make it get with the insurance companies to get you know surgeries done. Not wait two or three weeks for the call back, had a problem with that either day. Thanks.

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
Dr. Greaves is the most gentle, kind doctor I've ever spoken to. Especially to be a male. His his mayor is just so comforting and I feel very secure in his care and I he's one of the best doctors I've ever been to a my entire life unfortunately I've been to a lot of doctors. Thank you.
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.
December 03, 2020
