I highly recommend Dr. Dennis Chuck MD for Opthamology! HE IS GOOD! Very patient and kind man and willing to answer questions. I've been working with another Opthamologist who was rude. Impatient, and not wanting to answer questions. Dr. Dennis really took his time to explain possible complications and problems that could happen with a shifting or dislocated IOL lens, I'm thankful he took the time to make me feel comfortable and walk me through whether I should take the risk on the procedure and his recommendations. I think Dr. Dennis Chuck MD is awesome and I'll be coming to him in the future, read more

I visited a new eye doctor for my vision. I have dry macular degeneration and had cataracts procedure done on both eyes in 2022. The office was clean, and the staff was friendly and attentive. I didn't have to wait long in the lobby or to be seen. Dr. Chuck was quick and went straight to the point. I'll be coming back in two weeks for a laser procedure. I did feel a bit rushed, but overall the service was good. Would I recommend this place? I'm not sure yet. Date of visit: August 2025 read more

See all

Great doctor and staff. Always friendly and professional. I would recommend Dr. Chuck.

Dr Chuck is a caring, wonderful person. I am always confident that he will take care of any issues I have with my eyes. I highly recommend Dr Chuck. Unfortunately most of the office staff are rude and disrespectful. Don't expect to get information from them unless they absolutely have to give it. If you expect a warm and friendly smile you will be very disappointed. 5 stars for Dr Chuck and no stars for most of the office staff. read more

There are really nice people too. You won't go wrong by going to him. I promise you that I'm one of the pickiest people there is when it comes to my health. read more

I had a hard time trusting the process due to my terrible vision. I had double cataract surgeries. Hard during the interim without my glasses to rely on but now that the procedures are over and I have my new glasses, I am 100% thrilled . My vision is clear again and I'm amazed how beautiful our world is. Thank you thank you Dr Chuck. You're my hero ! read more

Dr. Chuck is such a wonderful person. He has the interest of the patient at the top of his concerns. He is so knowledgeable and understanding about making sure the patients are comfortable and fully understand what is going on, how they are affected and what he is doing to help them out. Amazing person. read more

Highly recommend this office - I took my elderly grandmother here for her exam & to purchase glasses & I can't explain how relieved I was that the staff was so patient with her as she has a hearing issue. Our optician Melissa was so kind & really took her time which I appreciate. We've since recommended friends here as well read more

Amazing service had surgery in my right eye in September he has been my ophthalmologist for five years and I admire his professionalism and dedication and such organization I highly recommend him read more

Dr. Chuck did an amazing job with both cataract surgeries. Thank you to you and your staff for your excellent surgeries and wonderful staff that went above and beyond to make it a fabulous experience. Thank you - now I have 20/20 vision. read more

I cannot say enough about this practice. I met Dr. Chuck for the first time this year, and subsequently had cataract surgery in one eye. I am very satisfied with the surgery itself, it was relatively painless and the improvement in my vision remarkable. The office staff is very courteous, the assistants are knowledgeable. They treat patients with respect and concern. The staff at the clinic was equally professional and attentive. The preparation and post op instructions were more than adequate. I am looking forward to next cataract removal and continuing to receive eye care from this practice. read more

I really really like Dr Chuck he helped me with a bad stye in my eye. I will continue to see him as needed so he gets 5 stars along with his nurse and two front counter women. Beware of rude office worker I give no stars for office worker I do have a complaint about office woman who was yelling and cussing at the employees. I went to counter and told lady that it's unprofessional for this type of language in this office full of patients. She just wouldn't stop yelling and cussing. They took it to another room but left the door open and the yelling continued. When she came I asked to speak to her and she put her hand in my face as to say talk to the hand. She walked away as I was talking to her and she just sarcasticly said to me (a patient) whatever many times to my face. I have worked in many companies and know this is unacceptable behavior especially when customers or patients are around. She just did not care the nurse apologized to me which was very nice of her. But she wasn't the one who should've apologized. I am having trouble with the stars and how many to give. Dr Chuck this lady who works for you has no business working where there are customers or patients around. read more

Subpar experience, probably would not choose to walk in here if it weren't for insurance referral sending me here. Office and equipment not updated. Staff could definitely be trained more. With so many places you can purchase glasses nowadays, not sure why this optical would be appealing. Doctor is still a doctor and competent enough to handle certain conditions (cataract, stye), but perhaps not the best bedside manner due to office being so busy. No big draw to go here, seek out other options if possible, especially if you have an advanced condition. read more

Dr. Chuck is an amazing doctor! He helped us so much. I can see 2020 now and it's a miracle! I highly recommend him he's very nice and kind and also wise. read more

Terrific Doctor. Very Knowledgeable. Very friendly. Great sense of Humor. Spends the right amount of time with you, explains everything. The cataract surgery went very fast and the result were great. Now waiting for then next eye to be done. The office staff were great too. Friendly and helpful. If you need an Eye Doctor you need look no further. read more

Dr. Chuck did two cataract surgeries (left/right) on me. They were both successful. I now have 20/20 vision. No glasses needed whatsoever. Opted for the lens upgrade. The office is run like a Swiss clock. Everyone has a specific job and there is no time wasted. The clients are elderly (geriatric). Dr. Chuck is a cut-to-the-chase kind of doctor. No small talk. He gets his business done and you are out of there. If you like your hand held or have the need to feel special this doctor is not for you. His office is always crowded and often there is no parking. He spends very little time with you and knows what he's doing. You have to speak up if you have questions and he will take the time to answer them. He can be quite humorous at times. He performs his surgeries at Pomona Valley Medical Center. It's the best hospital I have ever been in. Would not go anywhere else for anything. It was a win/win for me. Only 4 **** stars because of the waiting room times. read more

I really don't know what the bad reviews are about. This doctor was thorough and I didn't have to wait that long to be seen. The office staff is efficient which I greatly appreciate. I had a good experience. I'm glad I was referred to this ophthalmologist. read more

This guy is a (POS) he did surgery on my eye and put a lens implant, after a couple of days I couldn't see it was very blurry, his office don't care they treat you like sheep just another invoice for them to charge insurance. I tried to setup a appointment to have a conversation with him and they told me I needed a referral from my doctor and I still had to pay him $10 co-pay before he would even have a conversation with me regarding the job he did on my eye, I had another office tell me it could be a loose lens so I told him and he gets offended, it's very easy for him not to give a crap since it's not his eye. I would not recommend this clown read more

One office visit was enough for me to say "No thanks." I found Dr. Chuck to be the most abrupt and arrogant doctor I've ever met. First visit and he said he needed a commitment right then and there for surgery two months out "so you don't waste my staff's time." Wow. read more

I went to see Dr. Chuck last October. I wasn't very happy when I left his office. I waited for over an hour to be seen, then I had my eyes dilated for the test, waited about 20 minutes longer. The doctor did a quick test. I actually came in because I was having uncomfortable feelings in my left eye, like something is scratching my eye and my eye aches afterward. I told him that this happens every few weeks but I can't find anything in my eye. I also needed new glasses so I was going to have a vision exam and get new glasses, because my vision has changed and my current glasses aren't right. Fortunately, my insurance covers most of the costs. After he took his initial test, he said there was nothing wrong with my eye (I still have this issue every two to three weeks, same eye, same feelings). Then he says "that's it", and I say, "I wanted my vision tested and new glasses". He said "I'm sorry I don't have time for that, I'm too busy, go see an optometrist". He really said that. So now I have to pay for the vision exam and new glasses. I was in his office for about 5 - 10 minutes. read more

Dr. Chuck has been our family ophthalmologist for over a decade, and we couldn't recommend him more highly. He is kind, a good listener, and thorough. His office is always buzzing with activity, but you rarely wait more than 10-15 minutes to see him. He has taken care of me, my Mom, my Dad, and my Uncle. And believe me...Dr. Chuck should have gotten a medal for treating my Uncle! read more

Dr.CHUCK is amazing. He gave me my life back . I can now drive at night and also have my depth perception back. I don't like seeing any negative reviews saying that people had to wait . This Dr. handles so many patients and has his running shoes on . He is very friendly and professional. read more

I was impressed by a colleagues glasses she purchased from this office. She loved the staff and the doctor. I had a very different experience. The front office was just ordinary and not pleasant at all. In fact they made two errors in setting up my annual exam which caused me to miss a year and a half checkup. When I finally saw the fine doctor I told him I had floaters. After the nurse dilated my eyes, he examined my eyes and said he wanted to see me in a month to get a new pair of glasses. My vision was blurred and still had floaters. My sister suggested I go to Costco and get my glasses and I did. The Optometrist there gave me an exam and took an additional picture of my eyes and identified my problem. I have a diseased retina, aged macula degeneration. I went back to the fine doctor and told about my examine. He was very irritated and not happy at all about my report. He looked at my eyes and said, "Yea, you do have floaters and yes you have macula. He wrote me a prescription for A-reds and said, "There's nothing you can do about it and you may or not go blind." He knew he was negligent in his care for me and the visit was no charge. Needless to say, I have found a great doctor that is really concerned and cares about his patients. read more

Having Dr. Chuck do my cataract surgery was the best decision I could have made, He came very highly recommended from my optometrist and I am delighted to say I could not have been in better hands.. The surgery was amazing, I couldn't believe that it was over so fast {Ive had a worse time having my teeth cleaned} I had the contact implants put in and I am delighted with the results, no more contacts or glasses, perfect vision , I can pick up a book and read the smallest print. Life is good thanks to Dr Chuck.. read more

Dr. Chuck performed two miracles on me. Firstly, the surgery for a cataract was amazing. My vision is now perfect! Words cannot express the gratitude that I feel for a doctor who has done this for me. Secondly, I had three falls last year resulting in a life changing injury for me. After Dr. Chuck performed my cataract surgery I now have my balance back and no longer have to walk with a cane. Before the surgery, I had no depth perception, that is why I kept falling. Also, thank you to Dr. Chuck's amazing office staff who always were so very helpful. Thank you to Pomona Valley hospital who also were amazing. What a wonderful facility they have. I believe, for me, this is a life changing surgery. read more

Dr. Chuck performed cataract surgery on both eyes. I found the process from beginning to end very professional and satisfying. He staff is pleasant and professional as well. I would not hesitate to strongly recommend Dr. Chuck to my family and friends. read more

Dr. Chuck has been our high doctor for many years he was my wife's doctor before he was mine and hers is always been pleasant always been professional professional greeted you with a big smile and does excellent work I just had a cataract taken out of my left eye has the right one done a few years ago anything he doesn't need to and is very great doctor read more

Dr. Chuck did my mother's cataract surgery some time ago. She ended up with cross eyed vision. Not good. He recommended a doctor to put prism in the lens of her glasses to correct it, but it never should have been bad to begin with. There were only two eye doctors in all of Southern California that could make those lenses. I am sorry I did not do better research and find a better doctor. I would never let him do anything with my eyes. read more

Great doctor! Got both eyes done, a month a part. Very happy with results. Very personable, staff is great also. No long waits. Answers all questions and concerns. Highly recommend! read more

I had eye surgery for both eyes and I could not be happier. The wait time in office very quick.. All staff very nice.. I would highly recommend Dr Chuck for any eye problems you might have. read more

The staff is good and Dr. Chuck is good....the problem is overbooking of appointments. I have waited over an hour and have never had a wait of under 30 minutes. I can understand emergencies, but not every day. read more

Dr Chuck is a excellent Ophthalmologist... He is so overbooked because many HMO's require the doctor to schedule appointments every 5 to 8 minutes... If you want to spend plenty of time with your doctor... Go to a doctor that does not take HMO"s read more

Dr. Chuck is an ok guy, he's nice enough. His office is orderly, clean... convenient parking. Open on Saturdays as long as you make your appointment far enough in advance. BUT... His receptionist is so bitchy. She's short and tight lipped with her answers. Doesn't matter if I call in the morning, or afternoon, it's gonna bother her. If I don't have to put up with her kind, I don't. Anyway, I had to switch to Pomona Valley Optometry. So far Dr. Khanh Le and staff seem to be better. read more

I think they overbook appointments. I only come here because the contact lense exam is free. Waiting an hour for an appointment is to long. My visit with the Dr. lasted only a few minutes. read more

Dr. Chuck did my cataract surgery and I had a great experience here, The staff was always friendly and professional, The surgery was quick and painless and although I still have one eye to go as I had cataracts in both, the eye that had the surgery is almost perfect again. All told extremely satisfied. read more

Horrible experience. Went in for irritated corner of my eye. Had appointment and waited an hour still. Then when I get in Dr. Chuck rushes me so he can "go to lunch". As a patient, give me my time and don't concern me with your hungry belly. He spent no more than 3 minutes with me before his lunch and told me something that horrified me. He said i likely have herpes in my eye and that surgery may be required to save my eye. I was in shock and he said it with no concern except for having to go to his lunch! I asked if he's sure about the diagnosis and he was irritated with my question and rushed me out of the office. I got a second opinion with Dr. Peter Chen in West Covina who was more caring, patient and didnt talk about lunch. He said it was a simple infection and would go away with a little ointment and that eye herpes are extremely rare and that i absolutely don't have that. What a nightmare. read more
