good experience


Very pleased with the care given.


Dr. Graven is the best!


Dr. Grevin is the best, ever!


both professional and compassionate as he outlined options


When I told Dr. Greven that I wasn't sure when I might be available for my next appointment in 10 weeks because of the birth of a grandson in Seattle, he was very understanding. He said to go ahead and schedule the appointment for 10 weeks, and if I found out that I would be out of town then, to call and reschedule or email him. He also made note of this in my records which I thought was very considerate.


Dr. Craig Greven is one of the best doctors that I have ever had. The other doctor which had treated my eyes at your institution was Dr. Murphy Madison Slusher. He and Dr. Greven are the best doctors that a patient whih a retinal eye problem could ask for.


Very pleased with provider.


Dr. Craig Greven is the best...


Dr. Craig Graven is an excellent doctor. He has been taking care of a rare genetic retina disorder I have had for 8 years. He has always shown the utmost concern and care for me during this illness. I highly recommend him to anyone with eye issues.


this doctor is the best!


complete satisfaction


Dr. Greven is a great care provider


I trust this doctor completely and would definitely recommend him to anyone who wanted my opinion.


Dr. Graven is the best!


This provider continues to be very important to my health.


I tell anyone with retinal issues to see Dr. Greven first. I am so grateful that I serendipitously fell into his capable hands. He helped restore my sight!


Dr Greven is a wonderful physician - in both his expert, professional care and his caring attitude.


I could not ask for a better skilled or more attentive doctor. His colleagues who examined my eye all agreed that his surgical work produced beautiful results. That said quite a lot to me.


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!

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.
