So professional and knowledgeable plus caring. The best.


Some time ago Dr. Greven repaired my detached retina This was my annual check-up. I am very confident in his abilities and grateful to him for saving my eyesight. I have recommended him many times.


I would recommend this care provider!


This doctor has saved my sight several times and knows what he is doing. I have been a Diabetic since 1952 and he keeps me going.


Dr. Grevin and medical assistants are superb.


Excellent services


Dr Greven is one of the most caring physicians I have ever seen. He listens and considers what I think. Of course, my eye sight is very important to me and he takes my care very seriously.




very good


Dr Greven reassures me as I deal with a serious eye issue. He is very clear stating the facts. I appreciate him as my Doctor very much.


It's all good. Read previous comments.


Dr. Grevin is and has been an excellent provider.


*Dr. Greven, professional, wonderful, excellent surgeon.


Totally happy with this provider!


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!!
