Dr. Greven is, I believe, the department chair and has a superlative reputation with everyone I know who has been a patient of WFUBMC Ophthalmology. My eyes are in no better hands, and he is a great source of comfort to me because of that. But while reputation, position, and qualifications, are benefits to the quality of care, they can create a down-side, an intimidating aura to the common patient who is already anxious as to losing their quality of life through vision-loss, perhaps forever. During our interaction, he seems very focused and preoccupied to the point that he rarely makes eye-contact (pardon the pun). When I ask questions (I am fairly well-spoken, an accomplished public speaker, an educator, and with two graduate degrees) , he seems to cut me off at times when I pause and he then jumps to the answer, certainly not in a mean-spirited or discourteous manner, but rather as if he has to hurry and get on to the next patient. I realize that he is in a business and has patients all day, but I just feel rather "small" and inconsequential and that he needs to get our exam done quickly and get on with the next patient. Like I'm part of an assembly line. As a result, I just don't get the feeling that I've had the opportunity to get all of my questions asked or my concerns voiced to the point of comfort and confidence. Or if I did get an answer, but am still not clear, I don't feel comfortable asking for clarification or a follow-up. Certainly, to his credit, he asks if I have other questions, and I completely believe that his heart is in the right place, but I don't get the feeling of....patience. A tip would be to cross his legs, clasp his hands in his lap, smile, and ask the patient if they have any plans for the weekend or Thanksgiving, followed by a smile--just something to break the ice and establish a comfortable rapport on a human level. Take just one minute to exchange pleasantries and small talk, to make the connection. I just feel anxious and do not feel relaxed. I feel like the exam is an interaction between the doctor and my eyes; as the patient, the remainder of the body, I am a third wheel! :-) If my lack of my comfort during the exam/treatment "process," as outlined in these comments, is the "cost"--for lack of a better term--of my benefitting from Dr. Greven's vast knowledge and skill in order to preserve what vision I have remaining, then so be it. I will continue without hesitation to seek his superior care--I want no other.




he has saved my sight and is an excellent doctor!! Do not want to lose him!!


Couldn't be more pleased with my doctor. #9. The best!


Very good.


It probably seems odd to you in that I have indicated the very best for Dr. Graven and his staff. I assure you I gave truthful replies to your questions. I feel each and everyone in the office including the doctor, the assistant who documents his notes while dictating as he examines me and the results of tests his technician accomplished. Each do a remarkable job and I am impressed with their expertise in taking care of my problem.


Excellent physician, Dr. Greven takes the time to explain all procedures!


I left a bad situation and chose *Dr. Greven by his reputation. My son-in-law is a PA with a group of doctors. He asked them who they would recommend, each named *Dr. Greven.


always good no complaints


I am amazed that Dr. Greven is able to give such undivided attention, when I know how busy he is with his many patients and administrative duties. He saw me through one of the worst ordeals of my life (detached retina and macula), wouldn't let me give up, and restored my sight. I think he's one of the best Retinologists and human beings in the world.


I could not have asked for better care.
