Dr. Greven always takes the time to make sure I understand my condition and its prognosis.


I have recommeded Dr. Greven to many people. He is a life savor.


Very pleased with the care that I received from Dr. Greven. Confident that he is an excellent retina specialist. I feel blessed that I could get in to see him.


Dr Greven exhibited great skill and compassion


Quite a bit of time was spent with the resident doctor, but Dr. Greven probably spent sufficient time with me, as the resident doctor had compiled all the background info I had given him, plus he did an exam himself. Therefore, Dr. Greven had most of the info he needed before he talked with me.


Best doctor ever; I have recommended to others.


I have total confidence in Dr Greven, his staff and associates. In fact, between Dr Michelle Patel, Dr Shree Karup (no longer on staff) and Dr Greven I feel my condition has stopped deteriorating, has stabilized and improved due to treatment performed by this group of professionals. I feel my sight would have deteriorated to a great degree without their intervention and sincere care. I would, and do, recommend Dr Greven and his staff at every opportunity.


Dr. Craig Grevn is an outstanding ophthalmologist, specializing in retina issues. I would highly recommend him to anyone needing medial attention in this important area of expertise.


Dr. Greven is one of the BEST!!


Very good.


Dr. Greven is the best.


Dr. Greven is a gifted doctor who has always provided me with the best of care. It is a pleasure to see him and be treated by him. I have the utmost confidence in him. In short, he is the best!


I have had no problem with my care provider.


*Dr. Greven is the most caring doctor I have ever had. I trust him and his professional opinion completely.


I regard *Dr. Greven highly - - - Professional and knowledgeable -


We are SO fortunate to have Dr. Grevin as our provider. TOP NOTCH!!! We trust him completely!!!


Total confidence in *Dr. C. Greven.


Dr Greven is a remarkable Doctor. I can't say enough good things about his knowledge, his expertise and his compassion. I have lost one of my eyes going to a different practice and heard about Dr Greven and he saved my other day. As far as I am concerned his is the best of the best and I am forever grateful for this Angel.


I have been a patient of the Eye Clinic at Wake Forest Baptist since 1999, visiting 1-2 times a year. This is the first visit I've ever had in which I felt my attention from the doctor and the visit with him was rushed and I did not receive the kind of care that I associate with the clinic. I had come with a specific problem for which I was seeking answers, even if at a later time, and as I said, the experience just seemed overly rushed. If this had been my first experience there, I would not be back. I do know that the clinic had many patients waiting to be seen and the staff and Dr. Grevenfelt some urgency to have them seen as soon as possible.


dr Greven is probrably the best health provider I have ever had he lets you know what he is going to do what to expect. he shows that he is concern and listens to you


I have extreme confidence in Dr Greven, appreciate his thoroughness and the manner in which he addresses me as patient - as a person - very direct and very caring.


I have complete confidence in Dr. Greven.


I have a problem keeping my eye open when being examined but everyone was patient with me.


The time I waited before being examined by the physician was appropriate, because my eyes were dilated for the exam. Dr. Craig Greven is an excellent physician & surgeon. He has earned my confidence and complete trust. I give him the highest possible rating.


He's awesome! We love Dr. Grevin the Great!


Have many times.


He is excellent.


insensitive to my condition


Have never had a bad experience.


I saw three people plus had a couple of tests before I actually saw the provider. All were good to very good in the area we were discussing.


Dr. Greven is the best.


Could not have ask for better doctors than *Dr. D_____ & *Dr. Greven - both found the problem with my eyes - and fixed them I can't_____ about both.


Good Experience


Very knowledgeable provider with good patient care manner.


Dr. Greven brings all of his knowledge, thoroughness and care to each appointment.


Dr Greven is wonderful. Professional. Caring. and very personable.


I am so thankful I can have this Doctor.


I have been a patient of Dr. Greven's going on 15 years. I would not ask for a better, more caring physician.


Dr. Grevin is AMAZING....friendly, professional, competent!


Thankful to have Dr. Greven and Sherry Kelly in my care.


My care and treatment were all professionally done.


Dr. Greven is very patient and verbal (explaining things to me). He always shakes my hand when entering the Examining Room and lets me know that I did well during the telling me "Perfect" as he exits. Some may think a doctor may be talking to himself...but NOT Dr. Greven. He encourages his patients and happy that I have relaxed!!! (My treatment is an injection of medication into my eye.)


Great doctor!


excellent care provided




I hope as long as I risk losing my eyesight, I have Dr. Greven to prevent that loss.


Dr. Greven is an incredible doctor. He is knowledgeable and professional and I really appreciate him! His scribe Mary is great too!


I trust and like the care provider that see me when I come there.


Great doctor.


Dr. Greven is the greatest!


Dr. Greven is very smart and kind.


I have been coming to Baptist since I was 26 years old with different eye issues. Dr. Greven was called in as a consultant on a problem I had in my late 40ies. He has been my Dr. since Dr. Slusher retired. I have a great trust in Dr. Greven and I am thankful for him and his staff.
