I haven't felt that my prescription was right for years. Ron did a fantastic job! I can finally see clearly again! Thank you so much!

Ron winkelmann took a look at my eyes and said he could see me quickly. I was in a rush to make it to another spot but was super overdue in getting new contacts (like 6 months overdue). He saw me in ten minutes and sent me off with my prescription. He said I was days/ weeks away from an eye infection. So glad he was able to see me promptly and on a whim like that. Straightforward and very respectable guy. Mahalo man! read more

Now, prices here can't be beat. So I'm not knocking that. But service? This is where our journey to the dark side begins. First, didn't realize that even the prepackaged glasses you buy in the warehouse have to be returned to the Optical department. So wasted my time standing in the wrong line only to be shuttled to the Optical department. When I get to the Optical department, there is one woman ahead of me, NOT being helped and a couple of workers shuffling around, looking extremely busy. I check the number dispenser and it is empty so I figured, it's early, no one else is around so they aren't calling numbers. Then this one guy, let's call him "Kyle", because that's what his name tag says, "Kyle" calls out a number! He calls out, "One!" So the woman raises her number. I'm like, what the heck? Where did she get this number from? Is there another secret number dispenser hidden in a VIP lounge that I am unaware of? So I tell "Kyle", "Um, there are no numbers in this doohicky thing here." And you know what "Kyle" says to me, in a not un-sneery voice? "You don't need a number. You're the only one here so you're next anyway." Uh excuse me? If I don't need a number, then why the heck are you calling them out? I may not belong to Mensa but that sure makes no sense to me. So when "Kyle" finishes with the woman, he comes over to me because, well, I'm next cuz there's no one else around and there are no numbers because I don't need one (see, I'm smart enough to know how to use sarcasm). He says, "You returning these?" I say, "Yes". I'm ready to burst and spill my extended lamentation of why these sunglasses must go back. It was going to be epic! But I'm not given an opportunity. Instead, he says, "You want a copy of the receipt?" Uh, "Yes" again. I've suddenly become monosyllabic. What has happened? The force is strong with this one. And he sent me away. 10 words and I was walking out the door. I felt like a stormtrooper talking to Obi Wan. "These aren't the sunglasses you are looking for...move along..." Here's the kicker for Costco. My plan was to buy a replacement pair of sunglasses right after I returned these. But with that attitude, I kept walking out the door. My next pair will come from somewhere else. Not that my paltry budget for sunglasses would even be noticed by Costco. And I know full well, I'll be back at Costco next week. But sometimes you gotta be a rebel and fight for the cause, right? May the force be with you...just not at Costco. read more

Dr. Winkelman was awesome. First of all, he just does basic exams, so unlike the other Costco Optical docs, he can see you without a 2+ month wait. You can get an appointment within a reasonable time frame. He was awesome with my 9 year old first time contacts wearer. He was on time. Very quick but accurate. He even hooked ME up with contacts that everyone else said had to be ordered. Will definitely come here again. Thank you Dr. Winkelmam read more

Ron is the man! He's fast, friendly, and professional. The deals on glasses and contacts can't be beat, and my prescription is always in stock. read more

Dr. Wink is totally down to earth and I find him extremely personable. Been going here for 5 years. He doesn't sugar coat things and he's direct. He's also funny and I never feel uncomfortable or rushed. He always listens to my concerns and addresses them throughly. Plus he hooks me up with tons of samples which tends to hold me over for 6 months or so!! Dr. Wink is cool and I never feel like he's being condescending or being a dick. He's like a friend you can shoot the shit with. read more

Ron winkleman is the best. Knows what he's doing, plus he has a great personality. Straight to the point.

Didn't realize I needed an appointment to get my eyes checked, but Wendy (the receptionist) was super helpful and squeezed me in! Dr. Winkelman was also super helpful and quick when doing my eye exam! His sense of humor may throw some people off, but I think he's just trying to make conversation. He gave me two trials for contacts so I could see which ones were better for my eyes too! read more

I hadn't plan to return to this office for my eye exam and contacts since the last time I went, the doctor didn't seem very personal and I remember there being something odd about the amount I ended up paying for the exam. However, I noticed that the doctor had a couple of great Yelp reviews so I gave the office a call. The good: - the receptionist had a same day appointment available (on a Saturday) and even had Sunday appointments available. The not-so-good: - the receptionist wasn't able to give me a clear expectation of how much I would be charged for the exam. She said she had no idea what my insurance (VSP) covered and couldn't check the system to find out or the claim would be denied. I'm so confused. I will find somewhere else to go. :/ read more

Zero stars!!Avoid this place!!!Will never go there again. Called in on 5/7/18 at 11:15am to make an appointment. Was told the only time was at 2pm. I asked could they see me now since i had a previous appointment. He asked if i was an existing customer. I told him i was and gave my name. He told me if i came in right away , he could see me after a15 min wait. I told him I'd be there in 15 minutes. Drove in from town and was told to wait on seat outside. Waited for over an hour and finally called and asked how much longer? Was told 5 minutes. Waited 30 minutes more and finally had to leave since i had a scheduled meeting at 1:30. Totally unprofessional, wasted my whole morning. Zero stars! read more

Dr.Winkelman was really nice and very professional. This was my first experience of eye exam in the States and it was pleasant. Thanks!

Ron is GREAT. Friendly and willing to go the extra distance to make his patients happy. I needed contacts last minute because I was going out of the country, but waited too long to reorder and they didn't have what I needed in stock. I thought I was out of luck until Ron called me personally a few minutes after getting off the phone with his office, and told me he would put together a bag of samples for me until I could come in and order a full supply when I got back from vacation. He helped me out big time when he didn't have to, and that is the excellent customer service that is so rare these days. Not only that, I asked him for his address to send him a gift card or something as a thank you, and he asked me to please not do that, that he was just happy to help. Amazing. I rarely take the time to leave written reviews on places, but for this I had to. Definitely make an appointment with him if you need glasses or contacts, you won't find anyone better. read more

Went here couple months back, my last contact ripped so it was an emergency and I needed a new eye exam. My doc was doctor Ron. I had vision under vsp but didn't know I wasn't covered til I got there, even though I verified over the phone that it was. Anyway, after calling my insurance and feeling rushed by the staff I went in for my exam, it was really quick (still felt rushed but I didn't want to be rude), got my contacts, took me a few months to adjust to them. Overall I probably wouldn't go here anymore ‍ read more

Winkelman is impatient and disrespectful. He's got an attitude problem and Costco needs to start recording his phone line to listen how he treats customers over the phone. Bad image for the company. read more

Doctor Ronald H, he is an amazing and kind doctor. Super friendly and down to earth. Likable and easy going personality. Seeing him for the second time. Fast and fun. Will be back read more

I am a new patient of Dr. Ron Winkelman and must say that it's nice to finally find an Optometrist that is no nonsense and has an awesome "chairside" manner to boot. Dr. Ron was very intuitive and professional and made my visit painless and so worth the price! I'm self pay. 2 thumbs way up. read more

I've been on my last pair of contacts and really needed some more for work right away. Dr. Winkleman scheduled me in the same day I called and it was really easy to see him. He was very kind and made sure the equipment was sanitized before we started. Was super helpful and I was out of there within 15 min. Thank You!! read more

I am so impressed with Dr. Ron Winkelman,OD. I had the best eye Dr experience I've had in 20years. I work in the medical field and hold doctors to a high standard, and he surpassed that standard! He was direct, explained everything clearly, and took the time He needed to get my prescription right! I did not feel rushed and I will definitely be returning to see him! Mahalos Dr. Winkelman for the excellent care! read more

Dr. Winkelman and his receptionist were really nice. I have Tricare as my insurance and they accept prime there. The receptionist was super nice and friendly. She wasn't boring and to herself. She engaged in conversation and was very informative and gentle during the initial eye tests. When I went into the back room with the Dr. he was very patient and caring. I can tell he pays close attention to detail and he is AWESOME! I have been to three different eye clinics on the island of Oahu but this is the best one. I live in Ewa beach but it's worth the drive to Iwilei. I will definitely be back. read more

If I could give 6 stars I would. Ron Winkelman took me in and even waited when they were closed! I work retail for 16 years and I know what great customer service is. Not only that but he wasn't even rushing the eye exam or was angry because his office was closed. He's a very friendly guy and I highly recommend him and he also does walk ins! read more

Come here if you can tolerate a doctor who's condescending, impatient, and unprofessional towards you. I was here with my father as a translator. This was a while back and I wrote an in store review on him as soon as I got out of his office. Save your money and go somewhere else. Tip to Ronald, have a sign up and let non English speaker knows you don't want to diagnose them. read more

A+ experience! The doctor took the time to educate me about contacts and provide me options moving forward. Most doctors do most spend time educating their clients and it was refreshing knowing that he wanted me to leave the office with all my options available. Highly recommend you see him if contacts or glasses are needed. read more

My coverage changed from Kaiser to HMAA. I tried to get an appointment and it would take 3 to 4 weeks. Until I found Dr. Winkelman. On a Friday afternoon at 3 his receptionist had gone for the day and he still fit me in as a walk-in. He is absolutely thorough and a wonderful, hard-working person. Any other doctor would have refused me (end of day, no help in the office, etc.). He told me to come back in twenty minutes and fit me in between appointments. He fixed my prescription and I am so thankful to him for his work ethic and intelligence. It's hard to find people like that today. read more

I didn't see the doctor but wanted to post a review based on my experience with the receptionist, Jojo. I was in a bind because I forgot to bring my contact lenses on our vacation and she quickly helped to sort it out for me. She was so friendly and helpful - Jojo made my day! read more

Haven't been to this place to get some contacts, but I stood waiting by the counter like an idiot. She could have at least told me to pull a number so she could serve me. I'm all about customer service and that just killed my mood and was a waste of time almost worst than waiting at T-Mobile if y'all are T-Mobile customers you know what I mean read more

Dr. Ron Winkelman is about the best optometrist I have seen in my 71 years. He has always given me the most courteous, friendly and thorough eye exams ever. He is very easy to talk to about my eyes, and he communicates well to a person like me who knows nothing about the eyes. His front office staff has also given me excellent service. They have always been great with setting same-day appointments, even on weekends. They always give me a written bill for insurance claims when asked. No hassle, no problems. BTW, I live in Hilo, and have been coming here for annual exams. I am that pleased with the service. read more

I have been going to Dr. Winkelman for years. He is by far the most honest and the best eye doctor I have ever met. He is extremely good at what he does. Making an appointment with him is easy because he is accommodating and flexible. Eye exams there are usually done quickly. It is great for someone like myself who has crazy schedules and don't really have the time for lengthy exams. I get what I need done in his office and get on with my day. Thank you Dr. Winkelman, for your great service! See you next week for my annual eye exam. Thank you for keeping my eyes healthy. read more

Went to Costco Iwiilei to order glasses that were long overdue. Actually we went to fill two prescriptions since they had such a great selection. It wasn't a surprise that there was already quite a line before we arrived although it was only 30 min after they opened. Fine enough because it gave us an opportunity to find the frames we wanted. After close to a half hour wait we were helped by Costco optical employee Nel. She was great to work with and made ordering a breeze. Unfortunately because of the amount of people wanting help, she had to endure an impatient customer who rudely complained about waiting. Nel took it in stride and treated the customer with kindness although there was really nothing she could do. I can only imagine the amount of anxious customers they have to deal with on a daily basis especially since this Costco is a flagship store. Having knowledgeable and customer service oriented people like Nel who have a calming demeanor is imperative for the store. Hats off to the Costco Iwiilei Optical Department. Not only do they offer great products at a great value, but their customer service is awesome. read more

I've had Nel work on my glasses several times - She's GOOD! A true pro who is kind & helpful (whether or not you're buying) and knows her stuff! Also Susan, another optical worker; patient, capable, and handles adjustments beautifully ... I couldn't be happier with the team Costco has assembled at Iwilei. The reading by the optometrist was outstanding; so-called "minor adjustments" that made a MAJOR FIX in my vision ... Very personable, "squeezed" me in without a wait, nor any rush - Costco picks the RIGHT staff (capable!), keeps them trained to be efficient, patient, & effective. Costco optical makes the difference! There are others who I haven't dealt with, but I have full confidence they're equally professional with we clients. Thank You, Costco Optical! read more

Went to see Doctor Ron yesterday and was very impressed with his professionalism! He is straight forward with no bull. Tu at the front desk was sweet. I would highly recommend him. Very good guy you don't find many doctors who actually spend the time to care. He did! Many Mahalo's. read more

Dr. Ron Winkelman was timely, courteous and friendly. This was not only the most efficient eye exam I've ever had, but the most fun as well. I hope he plans to stay for a long while because he's my new permanent eye doctor. read more

After 3+ years of trying to get a prescription that allowed me to see distance and reading in the same prescription (which was my norm) I had the good fortune to meet Dr. Ron Winkelman at Costco in downtown Honolulu. He was my 4th Optometrist in 3 years by the way. He spent the time needed with me, on three different occasions and acted as a liaison with the Costco staff to ensure that my prescription was correct and the settings for my lenses appropriate. I am so grateful. The previous Dr.s ( at Hawaii Kai Costco) when asked to reevaluate the prescription ( yes I went back repeatedly), all concluded they were "right" and I put the glasses I got in that prescription in a drawer and never wore them returning to a 4 yr. old pair of glasses. Having worn glasses since for over 50 years and progressives for 10 years I was at a loss as to why I couldn't get the correct fitting. I began to think perhaps I was just getting "old". Not the case. Thank you Dr. Winkelman, I am so deeply appreciative. Your professionalism, the time you were willing to give me, and your spot on prescription and help with the referral to the individuals making the lenses, all were exemplary. read more

Awesome! Is the one word experience with Dr. Winkleman. Friendly, great service, over and beyond what was expected. A friend warned me of the poor service she received not once but twice, don't bother to go there. With hesitation not only because of her comments but from negative reviews on Yelp, I took a chance anyway. I tore my contact lens and needed service and lenses like yesterday. Besides, everyone is entitled to have a bad day right. I am glad I took the chance. He saw me as soon as I walked in and gave me an extended eye exam and couple of extra lenses at no extra charge. I did mention my hesitation and he was concerned. The problem a year ago with a rude employee with unacceptable customer service was rectified. She was fired. The current receptionist was quick and friendly on the phone and in person. The service was 150% Top Shape! Mahalo nui loa for the outstanding service, Dr. Winkleman! read more
