Years ago while getting some new eyeglasses, my optometrist mentioned that my eye pressure was a little on the high side and recommended I go see an ophthalmologist. I was referred to Dr. Marshburn and have been seeing him for about six years now and have been very happy with his care. One drop of an inexpensive prescription eye drop in each eye nightly and my eye pressures have been stable and in a good range all these years lowering my risk for developing glaucoma. I go in for check-ups every four or five months. Dr. Marshburn is very personable and we always end up chatting about various topics during my visit. He is never in a rush and always asks if I have any questions at the end of my check-ups. All of the staff including the front office and various techs are very friendly and caring. I don't have vision insurance and their cash prices are reasonable. You only get one set of eyes, keep them in top shape! read more

Dr. Marshburn is very thorough and knowledgeable. I highly recommend him for all your eye checkups.

Dr. John Marshburn is an excellent opthalmologist and eye surgeon. His manner with patients is calm and informative. However, the staff are defensive and they do not manage the patient flow well. Waiting room can be filled to capacity. Staff are unwilling or incapable of giving an estimate of the wait time. If they could tell you that it will be an hour (folks have waited that long before being called back), you could choose to reschedule or come back in 50 minutes. I have been a patient for decades, but am finally fed up. I do not have time for this. I have a business to run. read more

I am seriously upset at his complete MISDIAGNOSIS of GLAUCOMA! I am only 51, healthy, non-smoker, etc. He diagnosed me with beginning signs of Glaucoma. He gave me glaucoma drops that I would have to take for the rest of my life. I didn't really care for him bc he really didn't answer my main question as to why my eye is always so red and bloodshot. Even the drops he gave me made my redness in my eye even worse than it was. Anyways I went to a Glaucoma Specialists (Dr. Zahra Ghiasi) in Irvine today to get a second opinion and she said NO I do not have glaucoma. She was so sweet and explained everything to me. She did way more testing than Marshburn did (with his very old equipment) She had all top, high tech equipment and said any Dr that says that needs to have 100% evidence to a glaucoma diagnosis. That is a very serious eye condition and you better be sure. What I do have is very severe dry eyes and told me what drops to use. Even she was upset that he told me that. I will be seeing her from now on. If you're thinking of going to Marshburn, think again and find an Ophthalmologist that's good and has top/current equipment for all the tests. And get a second opinion to confirm any serious eye problem. I'm glad I did! read more

I don't understand the bad reviews. I have had nothing but a positive experience and I go every 6 months for about 4 years now. Dr. Marshburn is fabulous, the staff is great! read more

Not happy what so ever with this office and service Dr doesn't know what is the problem and told me you should come again after waiting 50 mins They billed twice and 2nd bill after 10 months They said if you don't want to pay we send you to collection even we collect the money from insurance When I paid the bill said this is final read more

I had my first appointment and will never go back. The office staff are nasty. I had to change rooms times and his office staff burst into the exam without knocking and interrupted us mid conversation when they were making me a follow up appointment while I was standing there two of the staff were arguing about how long I had to wait before I could come back. I was there nearly 2 hours and got absolutely nothing resolved. read more

Dr. Marshburn is wonderful. He is so thorough and professional. He takes the time to really understand what his patients are experiencing and sincerely cares. I've been going to him for years and switched to his care after my previous ophthalmologist ordered a number of tests that cost me a small fortune. Dr. Marshburn is incredibly knowledgable and is very efficient with what treatments and tests he orders. His staff is very friendly and is good about following up with me. I highly recommend him! read more

and Dr Marshburn is as good as it gets! He is patient, gives extra attention to patient, I don't want him to blush BUT he is the greatest.......I highly recommend Dr. Marshburn. My husband had both eyes done last year ,and I had 1 eye done in February....other eye isn't ready yet but I sure would never go to any other Ophthalmologist other then DR. MARSHBURN! He is the BEST! read more

Dr. Marshburn is excellent. I have been seeing him for a couple of years following up on an optic nerve issue. I feel confident with him. His staff is nice. He doesn't keep you waiting too long. That's hard when a doctor practices solo. He's real busy and I guess that says that his patients come back. read more

I am extremely impressed with Dr. Marshburn. I have been seeing him for the past seven years. I was diagnosed with Glaucoma in my early forties, this is when he came into my life. He has been amazing in managing my issues. I have NOT had any increase in loss of vision under his care, and that is because of his care, follow-up and treatment. read more

I have been seeing Dr. Marshburn of about 3 years. Well run office with excellent staff. Since he is a only specialist in the office, time with him is at a premium. He can be rather abrupt. He orders many tests, conducted by his staff, and can be rather dismissive of questions. read more

I usually don't post reviews but I feel I must let people know of the very unsatisfactory and bad experience I had. Last Oct the optometrist I went to referred me to Dr Marshburn for further test results for high pressure and possible glaucoma. I started in November and after 5 months of visits, trying 5 different kinds of eye drops of which none were helping but only causing more difficulty and bad reactions. Each visit he kept suggesting I needed to get surgery for glaucoma since the drops weren't working. He's big on pushing surgery. With that said I decided to get a second opinion. Well, I'm happy to say that after seeing another specialist come to find out , I wasn't getting any results from the eye drops because I was misdiagnosed by Dr Marshburn... I don't have high pressure and glaucoma. I don't need eye drops. I don't need surgery. My eyes are fine. So I paid 5 months of copayments and the difference that my insurance didn't cover for nothing. Not to mention $60 for eye drops that he prescribed. I would NOT recommend him. Also and very important, on my last visit, the office staff asked if my marital status had changed. I asked why they need to know and was told to ask the doctor. Feeling that question was inappropriate I did ask Dr Washburn and he said that was one of the questions he is required by insurance to ask in order to get paid. I didn't respond, but went home and called my insurance and informed them of the situation. I was told by them that they do not have such a required list, and recommended I find another doctor. I rate Dr Washburn and his office no stars...but the system would not allow and locked in the one star. read more
